 ## Background
 
-libp2p is the product of a long and arduous quest to understand the evolution of the Internet networking stack. In order to build P2P applications, dev have long had to made custom ad-hoc solutions to fit their needs, sometimes making some hard assumptions about their runtimes and the state of the network at the time of their development. Today, looking back more than 20 years, we see a clear pattern in the types of mechanisms built around the Internet Protocol, IP, which can be found throughout many layers of the OSI layer system, libp2p distils these mechanisms into flat categories and defines clear interfaces that once exposed, enable other protocols and applications to use and swap them, enabling upgradability and adaptability for the runtime, without breaking the API.

 ### Extending libp2p skeleton
 
-libp2p becomes very simple and basically acts as a glue for every module that compose this library. Since it can be highly customized, it requires some setup. What we recommend is to have a libp2p build for the system you are developing taking into account in your needs (e.g. for a browser working version of libp2p that acts as the network layer of IPFS, we have a built and minified version that browsers can require)

+
+const libp2p = require('libp2p')

+
+Each one of these values is [an exponential moving-average instance](https://github.com/pgte/moving-average#readme).
+
+#### Stats update interval
+
+Stats are not updated in real-time. Instead, measurements are buffered and stats are updated at an interval. The maximum interval can be defined through the `Switch` constructor option `stats.computeThrottleTimeout`, defined in miliseconds.

+The libp2p implementation in JavaScript is a work in progress. As such, there are a few things you can do right now to help out:
 
- - Go through the modules and **check out existing issues**. This would be especially useful for modules in active development. Some knowledge of IPFS/libp2p may be required, as well as the infrasture behind it - for instance, you may need to read up on p2p and more complex operations like muxing to be able to help technically.

Some knowledge of IPFS/libp2p may be required, as well as the infrastructure behind it - for instance, you may need to read up on p2p and more complex operations like muxing to be able to help technically.
  - **Perform code reviews**. Most of this has been developed by @diasdavid, which means that more eyes will help a) speed the project along b) ensure quality and c) reduce possible future bugs.
  - **Add tests**. There can never be enough tests.

+# Peer Discovery Mechanisms
+
+A Peer Discovery module enables libp2p to find peers to connect to. Think of these mechanisms as ways to join the rest of the network, as railing points.
+
+With these system, a libp2p node can both have a set of nodes to always connect on boot (bootstraper nodes), discover nodes through locality (e.g connected in the same LAN) or through serendipity (random walks on a DHT).
+
+These mechanisms save configuration and enable a node to operate without any explicit dials, it will just work.
+
+## 1. Bootstrap list of Peers when booting a node
+
+For this demo, we will connect to IPFS default bootstrapper nodes and so, we will need to support the same set of features those nodes have, that are: TCP, mplex and SECIO. You can see the complete example at [1.js](./1.js).
+
+First, we create our libp2p bundle.
+
+```JavaScript
+class MyBundle extends libp2p {
+  constructor (peerInfo) {
+    const modules = {
+      transport: [new TCP()],
+      connection: {
+        muxer: [Mplex],
+        crypto: [SECIO]
+      },
+      discovery: [new Railing(bootstrapers)]
+    }
+    super(modules, peerInfo)
+  }
+}
+```
+
+In this bundle, we use a `bootstrappers` array listing peers to connect _on boot_. Here is the list used by js-ipfs and go-ipfs.
+
+```JavaScript
+const bootstrapers = [
+  '/ip4/104.131.131.82/tcp/4001/ipfs/QmaCpDMGvV2BGHeYERUEnRQAwe3N8SzbUtfsmvsqQLuvuJ',
+  '/ip4/104.236.176.52/tcp/4001/ipfs/QmSoLnSGccFuZQJzRadHn95W2CrSFmZuTdDWP8HXaHca9z',
+  '/ip4/104.236.179.241/tcp/4001/ipfs/QmSoLPppuBtQSGwKDZT2M73ULpjvfd3aZ6ha4oFGL1KrGM',
+  '/ip4/162.243.248.213/tcp/4001/ipfs/QmSoLueR4xBeUbY9WZ9xGUUxunbKWcrNFTDAadQJmocnWm',
+  '/ip4/128.199.219.111/tcp/4001/ipfs/QmSoLSafTMBsPKadTEgaXctDQVcqN88CNLHXMkTNwMKPnu',
+  '/ip4/104.236.76.40/tcp/4001/ipfs/QmSoLV4Bbm51jM9C4gDYZQ9Cy3U6aXMJDAbzgu2fzaDs64',
+  '/ip4/178.62.158.247/tcp/4001/ipfs/QmSoLer265NRgSp2LA3dPaeykiS1J6DifTC88f5uVQKNAd',
+  '/ip4/178.62.61.185/tcp/4001/ipfs/QmSoLMeWqB7YGVLJN3pNLQpmmEk35v6wYtsMGLzSr5QBU3',
+  '/ip4/104.236.151.122/tcp/4001/ipfs/QmSoLju6m7xTh3DuokvT3886QRYqxAzb1kShaanJgW36yx'
+]
+```
+
+Now, once we create and start the node, we can listen for events such as `peer:discovery` and `peer:connect`, these events tell us when we found a peer, independently of the discovery mechanism used and when we actually dialed to that peer.
+
+```
+let node
+
+waterfall([
+  (cb) => PeerInfo.create(cb),
+  (peerInfo, cb) => {
+    peerInfo.multiaddrs.add('/ip4/0.0.0.0/tcp/0')
+    node = new MyBundle(peerInfo)
+    node.start(cb)
+  }
+], (err) => {
+  if (err) { throw err }
+
+  // Emitted when a peer has been found
+  node.on('peer:discovery', (peer) => {
+    console.log('Discovered:', peer.id.toB58String())
+    // Note how we need to dial, even if just to warm up the Connection (by not
+    // picking any protocol) in order to get a full Connection. The Peer Discovery
+    // doesn't make any decisions for you.
+    node.dial(peer, () => {})
+  })
+
+  // Once the dial is complete, this event is emitted.
+  node.on('peer:connect', (peer) => {
+    console.log('Connection established to:', peer.id.toB58String())
+  })
+})
+```
+
+From running [1.js](./1.js), you should see the following:
+
+```bash
+> node 1.js
+Discovered: QmaCpDMGvV2BGHeYERUEnRQAwe3N8SzbUtfsmvsqQLuvuJ
+Discovered: QmSoLnSGccFuZQJzRadHn95W2CrSFmZuTdDWP8HXaHca9z

+Connection established to: QmSoLSafTMBsPKadTEgaXctDQVcqN88CNLHXMkTNwMKPnu
+```
+
+## 2. MulticastDNS to find other peers in the network
+
+For this example, we need `libp2p-mdns`, go ahead and `npm install` it. You can find the complete solution at [2.js](./2.js).
+
+Update your libp2p bundle to include MulticastDNS.
+
+```JavaScript
+class MyBundle extends libp2p {
+  constructor (peerInfo) {
+    const modules = {
+      transport: [new TCP()],
+      connection: {
+        muxer: [Mplex],
+        crypto: [SECIO]
+      },
+      // We set the interval here to 1 second so that is faster to observe. The
+      // default is 10 seconds.
+      discovery: [new MulticastDNS(peerInfo, { interval: 1000 })]
+    }
+    super(modules, peerInfo)
+  }
+}
+```
+
+To observe it working, spawn two nodes.
+
+```JavaScript
+parallel([
+  (cb) => createNode(cb),
+  (cb) => createNode(cb)
+], (err, nodes) => {
+  if (err) { throw err }
+
+  const node1 = nodes[0]
+  const node2 = nodes[1]
+
+  node1.on('peer:discovery', (peer) => console.log('Discovered:', peer.id.toB58String()))
+  node2.on('peer:discovery', (peer) => console.log('Discovered:', peer.id.toB58String()))
+})
+```
+
+If you run this example, you will see a continuous stream of each peer discovering each other.
+
+```bash
+> node 2.js
+Discovered: QmSSbQpuKrxkoXHm1v4Pi35hPN5hUHMZoBoawEs2Nhvi8m
+Discovered: QmRcXXhtG8vTqwVBRonKWtV4ovDoC1Fe56WYtcrw694eiJ
+Discovered: QmSSbQpuKrxkoXHm1v4Pi35hPN5hUHMZoBoawEs2Nhvi8m
+Discovered: QmRcXXhtG8vTqwVBRonKWtV4ovDoC1Fe56WYtcrw694eiJ
+Discovered: QmSSbQpuKrxkoXHm1v4Pi35hPN5hUHMZoBoawEs2Nhvi8m
+Discovered: QmRcXXhtG8vTqwVBRonKWtV4ovDoC1Fe56WYtcrw694eiJ
+```
+
+## 3. Where to find other Peer Discovery Mechanisms
+
+There are plenty more Peer Discovery Mechanisms out there, you can:
+
+- Find one in [libp2p-webrtc-star](https://github.com/libp2p/js-libp2p-webrtc-star). Yes, a transport with discovery capabilities! This happens because WebRTC requires a rendezvous point for peers to exchange [SDP](https://tools.ietf.org/html/rfc4317) offer, which means we have one or more points that can introduce peers to each other. Think of it as MulticastDNS for the Web, as in MulticastDNS only works in LAN.
+- Any DHT will offer you a discovery capability. You can simple _random-walk_ the routing tables to find other peers to connect to.
+- You can create your own Discovery service, a registry, a list, a radio beacon, you name it!

+# Encrypted Communications
+
+libp2p can leverage the encrypted communications from the transports it uses (i.e WebRTC). To ensure that every connection is encrypted, independently of how it was set up, libp2p also supports a set of modules that encrypt every communication established.
+
+We call this usage a _connection upgrade_ where given a connection between peer A to peer B, a protocol handshake can be performed that gives that connection new properties.
+
+A byproduct of having these encrypted communications modules is that we can authenticate the peers we are dialing to. You might have noticed that every time we dial to a peer in libp2p space, we always use its PeerId at the end (e.g /ip4/127.0.0.1/tcp/89765/ipfs/QmWCbVw1XZ8hiYBwwshPce2yaTDYTqTaP7GCHGpry3ykWb), this PeerId is generated by hashing the Public Key of the peer. With this, we can create a crypto challenge when dialing to another peer and prove that peer is the owner of a PrivateKey that matches the Public Key we know.
+
+# 1. Set up encrypted communications with SECIO
+
+We will build this example on top of example for [Protocol and Stream Multiplexing](../protocol-and-stream-multiplexing). You will need the module `libp2p-secio` to complete it, go ahead and `npm install libp2p-secio`.
+
+SECIO is the crypto channel developed for IPFS, it is a TLS 1.3 like crypto channel that established an encrypted communication channel between two peers.
+
+To add it to your libp2p bundle, all you have to do is:
+
+```JavaScript
+const SECIO = require('libp2p-secio')
+
+class MyBundle extends libp2p {
+  constructor (peerInfo) {
+    const modules = {
+      transport: [new TCP()],
+      connection: {
+        muxer: [SPDY],
+        // Attach secio as the crypto channel to use
+        crypto: [SECIO]
+      }
+    }
+    super(modules, peerInfo)
+  }
+}
+```
+
+And that's it, from now on, all your libp2p communications are encrypted. Try running the example [1.js](./1.js) to see it working.
+
+If you want to want to learn more about how SECIO works, you can read the [great write up done by Dominic Tarr](https://github.com/auditdrivencrypto/secure-channel/blob/master/prior-art.md#ipfss-secure-channel).
+
+Importante note: SECIO hasn't been audited and so, we do not recommend to trust its security. We intent to move to TLS 1.3 once the specification is finalized and an implementation exists that we can use.

+# Peer and Content Routing
+
+DHTs (Distributed Hash Tables) are one of the most common building blocks used when creating P2P networks. However, the name doesn't make justice to all the benefits it brings and putting the whole set of features in one box has proven to be limiting when we want to integrate multiple pieces together. With this in mind, we've come up with a new definition for what a DHT offers: Peer Routing and Content Routing.
+
+Peer Routing is the category of modules that offer a way to find other peers in the network by intentionally issuing queries, iterative or recursive, until a Peer is found or the closest Peers, given the Peer Routing algorithm strategy are found.
+
+Content Routing is the category of modules that offer a way to find where content lives in the network, it works in two steps: 1) Peers provide (announce) to the network that they are holders of specific content (multihashes) and 2) Peers issue queries to find where that content lives. A Content Routing mechanism could be as complex as a Kademlia DHT or a simple registry somewhere in the network.
+
+# 1. Using Peer Routing to find other peers
+
+This example builds on top of the [Protocol and Stream Muxing](../protocol-and-stream-muxing). We need to install `libp2p-kad-dht`, go ahead and `npm install libp2p-kad-dht`. If you want to see the final version, open [1.js](./1.js).
+
+First, let's update our bundle to support Peer Routing and Content Routing.
+
+```JavaScript
+class MyBundle extends libp2p {
+  constructor (peerInfo) {
+    const modules = {
+      transport: [new TCP()],
+      connection: {
+        muxer: [Mplex],
+        crypto: [SECIO]
+      },
+      // we add the DHT module that will enable Peer and Content Routing
+      DHT: KadDHT
+    }
+    super(modules, peerInfo)
+  }
+}
+```
+
+Once that is done, we can use the createNode function we developed in the previous example to create 3 nodes. Connect node 1 to node 2 and node 2 to node 3. We will use node 2 as a way to find the whereabouts of node 3
+
+```JavaScript
+const node1 = nodes[0]
+const node2 = nodes[1]
+const node3 = nodes[2]
+
+parallel([
+  (cb) => node1.dial(node2.peerInfo, cb),
+  (cb) => node2.dial(node3.peerInfo, cb),
+  // Set up of the cons might take time
+  (cb) => setTimeout(cb, 100)
+], (err) => {
+  if (err) { throw err }
+
+  // 
+  node1.peerRouting.findPeer(node3.peerInfo.id, (err, peer) => {
+    if (err) { throw err }
+
+    console.log('Found it, multiaddrs are:')
+    peer.multiaddrs.forEach((ma) => console.log(ma.toString()))
+  })
+})
+```
+
+You should see the output being something like:
+
+```Bash
+> node 1.js
+Found it, multiaddrs are:
+/ip4/127.0.0.1/tcp/63617/ipfs/QmWrFXvZr9S4iDqycyoyc2zDdrT1jg9wpdenUTdd1LTar6
+/ip4/192.168.86.41/tcp/63617/ipfs/QmWrFXvZr9S4iDqycyoyc2zDdrT1jg9wpdenUTdd1LTar6
+```
+
+You have successfully used Peer Routing to find a peer that you were not directly connected. Now all you have to do is to dial to the multiaddrs you discovered.
+
+# 2. Using Content Routing to find providers of content
+
+With Content Routing, you can create records that are stored in multiple points in the network, these records can be resolved by you or other peers and they act as memos or rendezvous points. A great usage of this feature is to support discovery of content, where one node holds a file and instead of using a centralized tracker to inform other nodes that it holds that file, it simply puts a record in the network that can be resolved by other peers. Peer Routing and Content Routing are commonly known as Distributed Hash Tables, DHT.
+
+You can find this example completed in [2.js](./2.js), however as you will see it is very simple to update the previous example.
+
+Instead of calling `peerRouting.findPeer`, we will use `contentRouting.provide` and `contentRouting.findProviders`.
+
+```JavaScript
+node1.contentRouting.provide(cid, (err) => {
+  if (err) { throw err }
+
+  console.log('Node %s is providing %s', node1.peerInfo.id.toB58String(), cid.toBaseEncodedString())
+
+  node3.contentRouting.findProviders(cid, 5000, (err, providers) => {
+    if (err) { throw err }
+
+    console.log('Found provider:', providers[0].id.toB58String())
+  })
+})
+```
+
+The output of your program should look like:
+
+```bash
+> node 2.js
+Node QmSsmVPoTy3WpzwiNPnsKmonBaZjK2HitFs2nWUvwK31Pz is providing QmTp9VkYvnHyrqKQuFPiuZkiX9gPcqj6x5LJ1rmWuSySnL
+Found provider: QmSsmVPoTy3WpzwiNPnsKmonBaZjK2HitFs2nWUvwK31Pz
+```
+
+That's it, now you know how to find peers that have pieces of information that interest you!
+
+# 3. Future Work
+
+Currently, the only mechanisms for Peer and Content Routing come from the DHT, however we do have the intention to support:
+
+- Multiple Peer Routing Mechanisms, including ones that do recursive searches (i.e [webrtc-explorer](http://daviddias.me/blog/webrtc-explorer-2-0-0-alpha-release/) like packet switching or [CJDNS](https://github.com/cjdelisle/cjdns) path finder)
+- Content Routing via PubSub
+- Content Routing via centralized index (i.e a tracker)

+# Protocol and Stream Multiplexing (aka muxing)
+
+One of the specialties of libp2p is solving the bane of protocol discovery and handshake between machines. Before libp2p, you would have to assign a listener to a port and then through some process of formal specification you would assign ports to special protocols so that other hosts would know before hand which port to dial (e.g ssh (22), http (80), https (443), ftp (21), etc). With libp2p you don't need to do that anymore, not only you don't have to assign ports before hand, you don't even need to think about ports at all since all the protocol handshaking happens in the wire!
+
+The feature of agreeing on a protocol over an established connection is what we call _protocol multiplexing_ and it is possible through [multistream-select](https://github.com/multiformats/multistream), another protocol that lets you agree per connection (or stream) which protocol is going to be talked over that connection (select), it also enables you to request the other end to tell you which protocols it supports (ls). You can learn more about multistream-select at its [specification repo](https://github.com/multiformats/multistream).
+
+# 1. Handle multiple protocols
+
+Let's see _protocol multiplexing_ in action! You will need the following modules for this example: `libp2p`, `libp2p-tcp`, `peer-info`, `async` and `pull-stream`. This example reuses the base left by the [Transports](../transports) example. You can see the complete solution at [1.js](./1.js).
+
+After creating the nodes, we need to tell libp2p which protocols to handle. 
+
+```JavaScript
+// ...
+const node1 = nodes[0]
+const node2 = nodes[1]
+
+// Here we are telling libp2p that is someone dials this node to talk with the `/your-protocol`
+// multicodec, the protocol identifier, please call this callback and give it the connection
+// so that incomming data can be handled
+node2.handle('/your-protocol', (protocol, conn) => {
+  pull(
+    conn,
+    pull.map((v) => v.toString()),
+    pull.log()
+  )
+})
+```
+
+After the protocol is _handled_, now we can dial to it.
+
+```JavaScript
+node1.dialProtocol(node2.peerInfo, '/your-protocol', (err, conn) => {
+  if (err) { throw err }
+  pull(pull.values(['my own protocol, wow!']), conn)
+})
+```
+
+You might have seen this in the [Transports](../transports) examples. However, what it was not explained is that you can do more than exact string matching, for example, you can use semver.
+
+```JavaScript
+node2.handle('/another-protocol/1.0.1', (protocol, conn) => {
+  pull(
+    conn,
+    pull.map((v) => v.toString()),
+    pull.log()
+  )
+})
+// ...
+node1.dialProtocol(node2.peerInfo, '/another-protocol/1.0.0', (err, conn) => {
+  if (err) { throw err }
+  pull(pull.values(['semver me please']), conn)
+})
+```
+
+This feature is super power for network protocols. It works in the same way as versioning your RPC/REST API, but for anything that goes in the wire. We had to use this feature to upgrade protocols within the IPFS Stack (i.e Bitswap) and we successfully managed to do so without any network splits.
+
+There is still one last feature, you can create your custom match functions. 
+
+```JavaScript
+node2.handle('/custom-match-func', (protocol, conn) => {
+  pull(
+    conn,
+    pull.map((v) => v.toString()),
+    pull.log()
+  )
+}, (myProtocol, requestedProtocol, callback) => {
+  // This is all custom. I'm checking the base path matches, think of this
+  // as a HTTP routing table.
+  if (myProtocol.indexOf(requestedProtocol)) {
+    callback(null, true)
+  } else {
+    callback(null, false)
+  }
+})
+// ...
+node1.dialProtocol(node2.peerInfo, '/custom-match-func/some-query', (err, conn) => {
+  if (err) { throw err }
+  pull(pull.values(['do I fall into your criteria?']), conn)
+})
+```
+
+Try all of this out by executing [1.js](./1.js).
+
+# 2. Reuse existing connection
+
+The example above would require a node to create a whole new connection for every time it dials in one of the protocols, this is a waste of resources and also it might be simply not possible (e.g lack of file descriptors, not enough ports being open, etc). What we really want is to dial a connection once and then multiplex several virtual connections (stream) over a single connection, this is where _stream multiplexing_ comes into play.
+
+Stream multiplexing is a old concept, in fact it happens in many of the layers of the [OSI System](https://en.wikipedia.org/wiki/OSI_model), in libp2p we make this feature to our avail by letting the user pick which module for stream multiplexing to use.
+
+Currently, we have two available [libp2p-spdy](https://github.com/libp2p/js-libp2p-spdy) and [libp2p-mplex](https://github.com/libp2p/js-libp2p-mplex) and pluging them in is as easy as adding another transport. Let's revisit our libp2p bundle.
+
+```JavaScript
+const SPDY = require('libp2p-spdy')
+//...
+class MyBundle extends libp2p {
+  constructor (peerInfo) {
+    const modules = {
+      transport: [new TCP()],
+      // Here we are adding the SPDY muxer to our libp2p bundle.
+      // Thanks to protocol muxing, a libp2p bundle can support multiple Stream Muxers at the same
+      // time and pick the right one when dialing to a node
+      connection: {
+        muxer: [SPDY]
+      }
+    }
+    super(modules, peerInfo)
+  }
+}
+```
+
+With this, we can dial as many times as we want to a peer and always reuse the same established underlying connection.
+
+```JavaScript
+node2.handle('/a', (protocol, conn) => {
+  pull(
+    conn,
+    pull.map((v) => v.toString()),
+    pull.log()
+  )
+})
+
+node2.handle('/b', (protocol, conn) => {
+  pull(
+    conn,
+    pull.map((v) => v.toString()),
+    pull.log()
+  )
+})
+
+series([
+  (cb) => node1.dialProtocol(node2.peerInfo, '/a', (err, conn) => {
+    if (err) { throw err }
+    pull(pull.values(['protocol (a)']), conn)
+    cb()
+  }),
+  (cb) => node1.dialProtocol(node2.peerInfo, '/b', (err, conn) => {
+    if (err) { throw err }
+    pull(pull.values(['protocol (b)']), conn)
+    cb()
+  }),
+  (cb) => node1.dialProtocol(node2.peerInfo, '/b', (err, conn) => {
+    if (err) { throw err }
+    pull(pull.values(['another conn on protocol (b)']), conn)
+    cb()
+  })
+])
+```
+
+By running [2.js](./2.js) you should see the following result:
+
+```
+> node 2.js
+protocol (a)
+protocol (b)
+another protocol (b)
+```
+
+# 3. Bidirectional connections
+
+There is one last trick on _protocol and stream multiplexing_ that libp2p uses to make everyone's life easier and that is _bidirectional connection_.
+
+With the aid of both mechanisms, we can reuse an incomming connection to dial streams out too, this is specially useful when you are behind tricky NAT, firewalls or if you are running in a browser, where you can't have listening addrs, but you can dial out. By dialing out, you enable other peers to talk with you in Protocols that they want, simply by opening a new multiplexed stream.
+
+You can see this working on example [3.js](./3.js). The result should look like the following:
+
+```Bash
+> node 3.js
+from 1 to 2
+Addresses by which both peers are connected
+node 1 to node 2: /ip4/127.0.0.1/tcp/50629/ipfs/QmZwMKTo6wG4Te9A6M2eJnWDpR8uhsGed4YRegnV5DcKiv
+node 2 to node 1: /ip4/127.0.0.1/tcp/50630/ipfs/QmRgormJQeDyXhDKma11eUtksoh8vWmeBoxghVt4meauW9
+from 2 to 1
+```

+# Publish Subscribe
+
+Publish Subscribe is also included on the stack. Currently, we have on PubSub implementation which we ship by default [libp2p-floodsub](https://github.com/libp2p/js-libp2p-floodsub), with many more being researched at [research-pubsub](https://github.com/libp2p/research-pubsub).
+
+We've seen many interesting use cases appear with this, here are some highlights:
+
+- [Collaborative Text Editing](https://www.youtube.com/watch?v=-kdx8rJd8rQ)
+- [IPFS PubSub (using libp2p-floodsub) for IoT](https://www.youtube.com/watch?v=qLpM5pBDGiE).
+- [Real Time distributed Applications](https://www.youtube.com/watch?v=vQrbxyDPSXg)
+
+## 1. Setting up a simple PubSub network on top of libp2p
+
+For this example, we will use MulticastDNS for automatic Peer Discovery. This example is based the previous examples found in [Discovery Mechanisms](../discovery-mechanisms). You can find the complete version at [1.js](./1.js).
+
+Using PubSub is super simple, all you have to do is start a libp2p node, PubSub will be enabled by default.
+
+```JavaScript
+series([
+  (cb) => node1.once('peer:discovery', (peer) => node1.dial(peer, cb)),
+  (cb) => setTimeout(cb, 500)
+], (err) => {
+  if (err) { throw err }
+
+  // Subscribe to the topic 'news'
+  node1.pubsub.subscribe('news',
+    (msg) => console.log(msg.from, msg.data.toString()),
+    () => {
+      setInterval(() => {
+        // Publish the message on topic 'news'
+        node2.pubsub.publish(
+          'news',
+          Buffer.from('Bird bird bird, bird is the word!'),
+          () => {}
+        )
+      }, 1000)
+    }
+  )
+})
+```
+
+The output of the program should look like:
+
+```
+> node 1.js
+QmWpvkKm6qHLhoxpWrTswY6UMNWDyn8hN265Qp9ZYvgS82 Bird bird bird, bird is the word!
+QmWpvkKm6qHLhoxpWrTswY6UMNWDyn8hN265Qp9ZYvgS82 Bird bird bird, bird is the word!
+QmWpvkKm6qHLhoxpWrTswY6UMNWDyn8hN265Qp9ZYvgS82 Bird bird bird, bird is the word!

+QmWpvkKm6qHLhoxpWrTswY6UMNWDyn8hN265Qp9ZYvgS82 Bird bird bird, bird is the word!
+```
+
+## 2. Future work
+
+libp2p/IPFS PubSub is enabling a whole set of Distributed Real Time applications using CRDT (Conflict-Free Replicated Data Types). It is still going through heavy research (and hacking) and we invite you to join the conversation at [research-CRDT](https://github.com/ipfs/research-CRDT). Here is a list of some of the exciting examples:
+
+- [PubSub Room](https://github.com/ipfs-labs/ipfs-pubsub-room)
+- [Live DB - A always in Sync DB using CRDT](https://github.com/ipfs-labs/ipfs-live-db)

+# [Transports](http://libp2p.io/implementations/#transports)
+
+libp2p doesn't make assumptions for you, instead, it enables you as the developer of the application to pick the modules you need to run your application, which can vary depending on the runtime you are executing. A libp2p node can use one or more Transports to dial and listen for Connections. These transports are modules that offer a clean interface for dialing and listening, defined by the [interface-transport](https://github.com/libp2p/interface-transport) specification. Some examples of possible transports are: TCP, UTP, WebRTC, QUIC, HTTP, Pigeon and so on.
+
+A more complete definition of what is a transport can be found on the [interface-transport](https://github.com/libp2p/interface-transport) specification. A way to recognize a candidate transport is through the badge:
+
+[![](https://raw.githubusercontent.com/diasdavid/interface-transport/master/img/badge.png)](https://raw.githubusercontent.com/diasdavid/interface-transport/master/img/badge.png)
+
+## 1. Creating a libp2p Bundle with TCP
+
+When using libp2p, you always want to create your own libp2p Bundle, that is, pick your set of modules and create your network stack with the properties you need. In this example, we will create a bundle with TCP. You can find the complete solution on the file [1.js](./1.js).
+
+You will need 4 deps total, so go ahead and install all of them with: 
+
+```
+> npm install libp2p libp2p-tcp peer-info async
+```
+
+Then, on your favorite text editor create a file with the `.js` extension. I've called mine `1.js`.
+
+First thing is to create our own bundle! Insert:
+
+```JavaScript
+'use strict'
+
+const libp2p = require('libp2p')
+const TCP = require('libp2p-tcp')
+const PeerInfo = require('peer-info')
+const waterfall = require('async/waterfall')
+
+// This MyBundle class is your libp2p bundle packed with TCP
+class MyBundle extends libp2p {
+  constructor (peerInfo) {
+    // modules is a JS object that will describe the components
+    // we want for our libp2p bundle
+    const modules = {
+      transport: [new TCP()]
+    }
+    super(modules, peerInfo)
+  }
+}
+```
+
+Now that we have our own MyBundle class that extends libp2p, let's create a node with it. We will use `async/waterfall` just for code structure, but you don't need to. Append to the same file:
+
+```JavaScript
+let node
+
+waterfall([
+  // First we create a PeerInfo object, which will pack the
+  // info about our peer. Creating a PeerInfo is an async
+  // operation because we use the WebCrypto API
+  // (yeei Universal JS)
+  (cb) => PeerInfo.create(cb),
+  (peerInfo, cb) => {
+    // To signall the addresses we want to be available, we use
+    // the multiaddr format, a self describable address
+    peerInfo.multiaddrs.add('/ip4/0.0.0.0/tcp/0')
+    // Now we can create a node with that PeerInfo object
+    node = new MyBundle(peerInfo)
+    // Last, we start the node!
+    node.start(cb)
+  }
+], (err) => {
+  if (err) { throw err }
+
+  // At this point the node has started
+  console.log('node has started (true/false):', node.isStarted())
+  // And we can print the now listening addresses.
+  // If you are familiar with TCP, you might have noticed
+  // that we specified the node to listen in 0.0.0.0 and port
+  // 0, which means "listen in any network interface and pick
+  // a port for me
+  console.log('listening on:')
+  node.peerInfo.multiaddrs.forEach((ma) => console.log(ma.toString()))
+})
+```
+
+Running this should result in somehting like:
+
+```bash
+> node 1.js
+node has started (true/false): true
+listening on:
+/ip4/127.0.0.1/tcp/61329/ipfs/QmW2cKTakTYqbQkUzBTEGXgWYFj1YEPeUndE1YWs6CBzDQ
+/ip4/192.168.2.156/tcp/61329/ipfs/QmW2cKTakTYqbQkUzBTEGXgWYFj1YEPeUndE1YWs6CBzDQ
+```
+
+That `QmW2cKTakTYqbQkUzBTEGXgWYFj1YEPeUndE1YWs6CBzDQ` is the PeerId that was created during the PeerInfo generation.
+
+## 2. Dialing from one node to another node
+
+Now that we have our bundle, let's create two nodes and make them dial to each other! You can find the complete solution at [2.js](./2.js).
+
+For this step, we will need one more dependency.
+
+```bash
+> npm install pull-stream
+```
+
+We are going to reuse the MyBundle class from step 1, but this time to make things simpler, we will create two functions, one to create nodes and another to print the addrs to avoid duplicating code.
+
+```JavaScript
+function createNode (callback) {
+  let node
+
+  waterfall([
+    (cb) => PeerInfo.create(cb),
+    (peerInfo, cb) => {
+      peerInfo.multiaddrs.add('/ip4/0.0.0.0/tcp/0')
+      node = new MyBundle(peerInfo)
+      node.start(cb)
+    }
+  ], (err) => callback(err, node))
+}
+
+function printAddrs (node, number) {
+  console.log('node %s is listening on:', number)
+  node.peerInfo.multiaddrs.forEach((ma) => console.log(ma.toString()))
+}
+```
+
+Now we are going to use `async/parallel` to create two nodes, print their addresses and dial from one node to the other.
+
+```
+parallel([
+  (cb) => createNode(cb),
+  (cb) => createNode(cb)
+], (err, nodes) => {
+  if (err) { throw err }
+
+  const node1 = nodes[0]
+  const node2 = nodes[1]
+
+  printAddrs(node1, '1')
+  printAddrs(node2, '2')
+
+  node2.handle('/print', (protocol, conn) => {
+    pull(
+      conn,
+      pull.map((v) => v.toString()),
+      pull.log()
+    )
+  })
+
+  node1.dialProtocol(node2.peerInfo, '/print', (err, conn) => {
+    if (err) { throw err }
+
+    pull(pull.values(['Hello', ' ', 'p2p', ' ', 'world', '!']), conn)
+  })
+})
+```
+
+The result should be look like:
+
+```bash

+Hello p2p world!
+```
+
+## 3. Using multiple transports
+
+Next, we want to be available in multiple transports to increase our chances of having common transports in the network. A simple scenario, a node running in the browser only has access to HTTP, WebSockets and WebRTC since the browser doesn't let you open any other kind of transport, for this node to dial to some other node, that other node needs to share a common transport.
+
+What we are going to do in this step is to create 3 nodes, one with TCP, another with TCP+WebSockets and another one with just WebSockets. The full solution can be found on [3.js](./3.js).
+
+In this example, we will need to also install `libp2p-websockets`, go ahead and install:
+
+```sh
+> npm install libp2p-websockets
+```
+
+We want to create 3 nodes, one with TCP, one with TCP+WebSockets and one with just WebSockets. We need to update our `MyBundle` class to contemplate WebSockets as well:
+
+```JavaScript
+const WebSockets = require('libp2p-websockets')
+// ...
+
+class MyBundle extends libp2p {
+  constructor (peerInfo) {
+    const modules = {
+      transport: [new TCP(), new WebSockets()]
+    }
+    super(modules, peerInfo)
+  }
+}
+```
+
+Now that we have our bundle ready, let's upgrade our createNode function to enable us to pick the addrs in which a node will start a listener.
+
+```JavaScript
+function createNode (addrs, callback) {
+  if (!Array.isArray(addrs)) {
+    addrs = [addrs]
+  }
+
+  let node
+
+  waterfall([
+    (cb) => PeerInfo.create(cb),
+    (peerInfo, cb) => {
+      addrs.forEach((addr) => peerInfo.multiaddrs.add(addr))
+      node = new MyBundle(peerInfo)
+      node.start(cb)
+    }
+  ], (err) => callback(err, node))
+}
+```
+
+As a rule, a libp2p node will only be capable of using a transport if: a) it has the module for it and b) it was given a multiaddr to listen on. The only exception to this rule is WebSockets in the browser, where a node can dial out, but unfortunately cannot open a socket.
+
+Let's update our flow to create nodes and see how they behave when dialing to each other:
+
+```JavaScript
+parallel([
+  (cb) => createNode('/ip4/0.0.0.0/tcp/0', cb),
+  // Here we add an extra multiaddr that has a /ws at the end, this means that we want
+  // to create a TCP socket, but mount it as WebSockets instead.
+  (cb) => createNode(['/ip4/0.0.0.0/tcp/0', '/ip4/127.0.0.1/tcp/10000/ws'], cb),
+  (cb) => createNode('/ip4/127.0.0.1/tcp/20000/ws', cb)
+], (err, nodes) => {
+  if (err) { throw err }
+
+  const node1 = nodes[0]
+  const node2 = nodes[1]
+  const node3 = nodes[2]
+
+  printAddrs(node1, '1')
+  printAddrs(node2, '2')
+  printAddrs(node3, '3')
+
+  node1.handle('/print', print)
+  node2.handle('/print', print)
+  node3.handle('/print', print)
+
+  // node 1 (TCP) dials to node 2 (TCP+WebSockets)
+  node1.dialProtocol(node2.peerInfo, '/print', (err, conn) => {
+    if (err) { throw err }
+
+    pull(pull.values(['node 1 dialed to node 2 successfully']), conn)
+  })
+
+  // node 2 (TCP+WebSockets) dials to node 2 (WebSockets)
+  node2.dialProtocol(node3.peerInfo, '/print', (err, conn) => {
+    if (err) { throw err }
+
+    pull(pull.values(['node 2 dialed to node 3 successfully']), conn)
+  })
+
+  // node 3 (WebSockets) attempts to dial to node 1 (TCP)
+  node3.dialProtocol(node1.peerInfo, '/print', (err, conn) => {
+    if (err) {
+      console.log('node 3 failed to dial to node 1 with:', err.message)
+    }
+  })
+})
+```
+
+`print` is a function created using the code from 2.js, but factored into its own function to save lines, here it is:
+
+```JavaScript
+function print (protocol, conn) {
+  pull(
+    conn,
+    pull.map((v) => v.toString()),
+    pull.log()
+  )
+}
+```
+
+If everything was set correctly, you now should see the following after you run the script:
+
+```Bash
+> node 3.js
+node 1 is listening on:
+/ip4/127.0.0.1/tcp/62620/ipfs/QmWpWmcVJkF6EpmAaVDauku8g1uFGuxPsGP35XZp9GYEqs
+/ip4/192.168.2.156/tcp/62620/ipfs/QmWpWmcVJkF6EpmAaVDauku8g1uFGuxPsGP35XZp9GYEqs
+node 2 is listening on:
+/ip4/127.0.0.1/tcp/10000/ws/ipfs/QmWAQtWdzWXibgfyc7WRHhhv6MdqVKzXvyfSTnN2aAvixX
+/ip4/127.0.0.1/tcp/62619/ipfs/QmWAQtWdzWXibgfyc7WRHhhv6MdqVKzXvyfSTnN2aAvixX
+/ip4/192.168.2.156/tcp/62619/ipfs/QmWAQtWdzWXibgfyc7WRHhhv6MdqVKzXvyfSTnN2aAvixX
+node 3 is listening on:
+/ip4/127.0.0.1/tcp/20000/ws/ipfs/QmVq1PWh3VSDYdFqYMtqp4YQyXcrH27N7968tGdM1VQPj1
+node 3 failed to dial to node 1 with: No available transport to dial to
+node 1 dialed to node 2 successfully
+node 2 dialed to node 3 successfully
+```
+
+As expected, we created 3 nodes, node 1 with TCP, node 2 with TCP+WebSockets and node 3 with just WebSockets. node 1 -> node 2 and node 2 -> node 3 managed to dial correctly because they shared a common transport, however, node 3 -> node 1 failed because they didn't share any.
+
+## 4. How to create a new libp2p transport
+
+Today there are already 3 transports available, one in the works and plenty to come, you can find these at [interface-transport implementations](https://github.com/libp2p/interface-transport#modules-that-implement-the-interface) list.
+
+Adding more transports is done through the same way as you added TCP and WebSockets. Some transports might offer extra functionalities, but as far as libp2p is concerned, if it follows the interface defined at the [spec](https://github.com/libp2p/interface-transport#api) it will be able to use it.
+
+If you decide to implement a transport yourself, please consider adding to the list so that others can use it as well.
+
+Hope this tutorial was useful. We are always looking to improve it, so contributions are welcome!
