-## Scope
-
-We expect all members of the IPFS community to abide by this Code of Conduct
-at all times in all IPFS community venues, online and in person, and in one-on-one
-communications pertaining to IPFS affairs.
-
-This policy covers the usage of IPFS public infrastructure, including the
-IPFS.io HTTP gateways, as well as other IPFS websites, IPFS related events,
-and any other services offered by or on behalf of the IPFS community. It also
-applies to behavior in the context of the IPFS Open Source project
-communities, including but not limited to public GitHub repositories, IRC
-channels, social media, mailing lists, and public events.
-
-This Code of Conduct is in addition to, and does not in any way nullify or
-invalidate, any other terms or conditions related to use of IPFS services.
-
-The definitions of various subjective terms such as "discriminatory",
-"hateful", or "confusing" will be decided at the sole discretion of the IPFS
-abuse team.
-
-## Friendly Harassment-Free Space
-
-We are committed to providing a friendly, safe and welcoming environment for
-all, regardless of gender identity, sexual orientation, disability, ethnicity,
-religion, age, physical appearance, body size, race, or similar personal
-characteristics.
-
-We ask that you please respect that people have differences of opinion
-regarding technical choices, and that every design or implementation choice
-carries a trade-off and numerous costs. There is seldom a single right answer.
-A difference of technology preferences is not a license to be rude.
-
-Any spamming, trolling, flaming, baiting, or other attention-stealing
-behavior is not welcome, and will not be tolerated.
-
-Harassing other users is never tolerated, whether via public or private media.
-
-Avoid using offensive or harassing nicknames, or other identifiers that might
-detract from a friendly, safe, and welcoming environment for all.
-
-Harassment includes, but is not limited to: harmful or prejudicial verbal or
-written comments related to gender identity, sexual orientation, disability,
-ethnicity, religion, age, physical appearance, body size, race, or similar
-personal characteristics; inappropriate use of nudity, sexual images, and/or
-sexually explicit language in public spaces; threats of physical or non-
-physical harm; deliberate intimidation, stalking or following; harassing
-photography or recording; sustained disruption of talks or other events;
-inappropriate physical contact; and unwelcome sexual attention.
-
-Media shared through public infrastructure run by the IPFS team must not
-contain illegal or infringing content. You should only publish content via
-IPFS public infrastructure if you have the right to do so. This includes
-complying with all software license agreements or other intellectual property
-restrictions. You will be solely responsible for any violation of laws or
-others’ intellectual property rights.
-
-## Reporting Violations of this Code of Conduct
-
-If you believe someone is harassing you or has otherwise violated this Code of
-Conduct, please contact us at abuse@ipfs.io to send us an abuse report. If
-this is the initial report of a problem, please include as much detail as
-possible. It is easiest for us to address issues when we have more context.
-
-## Copyright Violations
-
-We respect the intellectual property of others and ask that you do too. If you
-believe any content or other materials available through public IPFS
-infrastructure violates a copyright held by you and you would like to submit a
-notice pursuant to the Digital Millennium Copyright Act or other similar
-international law, you can submit a notice to our agent for service of notice
-to: abuse@ipfs.io
-
-(We will add a physical mailing address here when we acquire one).
-
-Please make sure your notice meets the Digital Millennium Copyright Act
-requirements.
-
-## Consequences
-
-All content published to public IPFS infrastructure is hosted at the sole
-discretion of the IPFS team.
-
-Unacceptable behavior from any community member will not be tolerated.
-
-Anyone asked to stop unacceptable behavior is expected to comply immediately.
-
-If a community member engages in unacceptable behavior, the ipfs team
-may take any action they deem appropriate, up to and including a temporary ban
-or permanent expulsion from the community without warning (and without refund
-in the case of a paid event or service).
-
-## Addressing Grievances
-
-If you feel you have been falsely or unfairly accused of violating this Code
-of Conduct, you should notify the IPFS team. We will do our best to ensure
-that your grievance is handled appropriately.
-
-In general, we will choose the course of action that we judge as being most in
-the interest of fostering a safe and friendly community.
-
-On IRC, let one of the ops know if you think that someone has transgressed
-against the Code of Conduct. If you would like to be an op and promise to
-help maintain and abide by the code, please let us know.
-
-## Contact Info
-
-Please contact abuse@ipfs.io if you need to report a problem or address a
-grievance related to an abuse report.
-
-You are also encouraged to contact us if you are curious about something that
-might be "on the line" between appropriate and inappropriate content. We are
-happy to provide guidance to help you be a successful part of our community.

 ## 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
+### Creating your own libp2p bundle
 
-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).
+The libp2p module acts as a glue for every libp2p module that you can use top create your own libp2p bundle. Creating your own libp2p bundle gives you a lot of freedom when it comes to customize it with features and default setup. We recommend creating your own libp2p bundle for the app you are developing that takes in account your needs (e.g. for a browser working version of libp2p that acts as the network layer of IPFS, we have a built one that leverages the Browser transports).

+### Switch Stats API
+
+##### `libp2p.stats.emit('update')`
+
+Every time any stat value changes, this object emits an `update` event.
+
+#### Global stats
+
+##### `libp2p.stats.global.snapshot`
+
+Should return a stats snapshot, which is an object containing the following keys and respective values:
+
+- dataSent: amount of bytes sent, [Big](https://github.com/MikeMcl/big.js#readme) number

+
+##### `libp2p.stats.global.movingAverages`
+
+Returns an object containing the following keys:
+
+- dataSent
+- dataReceived
+
+Each one of them contains an object that has a key for each interval (`60000`, `300000` and `900000` miliseconds).
+
+Each one of these values is [an exponential moving-average instance](https://github.com/pgte/moving-average#readme).
+
+#### Per-transport stats
+
+##### `libp2p.stats.transports()`
+
+Returns an array containing the tags (string) for each observed transport.
+
+##### `libp2p.stats.forTransport(transportTag).snapshot`
+
+Should return a stats snapshot, which is an object containing the following keys and respective values:

+
+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.
+
+### Private Networks
+
+#### Enforcement
+
+Libp2p provides support for connection protection, such as for private networks. You can enforce network protection by setting the environment variable `LIBP2P_FORCE_PNET=1`. When this variable is on, if no protector is set via `options.connProtector`, Libp2p will throw an error upon creation.
+
+#### Protectors
+
+Some available network protectors:
+* [libp2p-pnet](https://github.com/libp2p/js-libp2p-pnet)

 ## Contribute
 
 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.

  - **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.

+# Delegated Routing with Libp2p and IPFS
+
+This example shows how to use delegated peer and content routing. The [Peer and Content Routing Example](../peer-and-content-routing) focuses
+on the DHT implementation. This example takes that a step further and introduces delegated routing. Delegated routing is
+especially useful when your libp2p node will have limited resources, making running a DHT impractical. It's
+also highly useful if your node is generating content, but can't reliably be on the network. You can use delegate nodes
+to provide content on your behalf.
+
+The starting [Libp2p Bundle](./src/libp2p-bundle.js) in this example starts by disabling the DHT and adding the Delegated Peer and Content Routers.
+Once you've completed the example, you should try enabled the DHT and see what kind of results you get! You can also enable the
+various Peer Discovery modules and see the impact it has on your Peer count.
+
+## Prerequisite
+**NOTE**: This example is currently dependent on a clone of the [delegated routing support branch of go-ipfs](https://github.com/ipfs/go-ipfs/pull/4595).
+
+## Running this example
+
+1. Install IPFS locally if you dont already have it. [Install Guide](https://docs.ipfs.io/introduction/install/)
+2. Run the IPFS daemon: `ipfs daemon`
+3. The daemon will output a line about its API address, like `API server listening on /ip4/127.0.0.1/tcp/8080`
+4. In another window output the addresses of the node: `ipfs id`. Make note of the websocket address, it will contain `/ws/` in the address.
+5. In `./src/libp2p-bundle.js` check if the host and port of your node are correct, according to the previous step. If they are different, replace them.
+6. In `./src/App.js` replace `BootstrapNode` with your nodes Websocket address from step 4.
+7. Start this example:
+
+```sh
+npm install
+npm start
+```
+
+This should open your browser to http://localhost:3000. If it does not, go ahead and do that now.
+
+8. Your browser should show you connected to at least 1 peer.
+
+### Finding Content via the Delegate
+1. Add a file to your IPFS node. From this example root you can do `ipfs add ./README.md` to add the example readme.
+2. Copy the hash from line 5, it will look something like *Qmf33vz4HJFkqgH7XPP1uA6atYKTX1BWQEQthzpKcAdeyZ*.
+3. In the browser, paste the hash into the *Hash* field and hit `Find`. The readme contents should display.
+
+This will do a few things:
+* The delegate nodes api will be queried to find providers of the content
+* The content will be fetched from the providers
+* Since we now have the content, we tell the delegate node to fetch the content from us and become a provider
+
+### Finding Peers via the Delegate
+1. Get a list of your delegate nodes peer by querying the IPFS daemon: `ipfs swarm peers`
+2. Copy one of the CIDs from the list of peer addresses, this will be the last portion of the address and will look something like `QmdoG8DpzYUZMVP5dGmgmigZwR1RE8Cf6SxMPg1SBXJAQ8`.
+3. In your browser, paste the CID into the *Peer* field and hit `Find`.
+4. You should see information about the peer including its addresses.

 # Echo example with libp2p
+
+This example performs a simple echo from the listener to the dialer.
+
+## Setup
+1. Install the modules, `npm install`.
+2. Open 2 terminal windows in the `./src` directory.
+
+## Running
+1. Run the listener in window 1, `node listener.js`
+2. Run the dialer in window 2, `node dialer.js`
+3. You should see console logs showing the dial, and the received echo of _hey_
+4. If you look at the listener window, you will see it receiving the dial

+# 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 (_options) {
+    const defaults = {
+      modules: {
+        transport: [ TCP ],
+        streamMuxer: [ Mplex ],
+        connEncryption: [ SECIO ],
+        // we add the DHT module that will enable Peer and Content Routing
+        dht: KadDHT
+      },
+      config: {
+        dht: {
+          kBucketSize: 20
+        },
+        EXPERIMENTAL: {
+          // dht must be enabled
+          dht: true
+        }
+      }
+    }
+
+    super(defaultsDeep(_options, defaults))
+  }
+}
+```
+
+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)

-![](http://1.bp.blogspot.com/-tNvSnCW0KlQ/U-KOKGVoJkI/AAAAAAAAA3Q/aiSLMeSJFtw/s1600/WIP-sign.jpg)
+# 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)
+- [IIIF Annotations over IPFS, CRDT and libp2p](https://www.youtube.com/watch?v=hmAniA6g9D0&feature=youtu.be&t=10m40s)
