 Besides the `modules` and `config`, libp2p allows other internal options and configurations:

+- `datastore`: an instance of [ipfs/interface-datastore](https://github.com/ipfs/js-ipfs-interfaces/tree/master/packages/interface-datastore) modules.

+#### Configuring the NAT Manager
+
+Network Address Translation (NAT) is a function performed by your router to enable multiple devices on your local network to share a single IPv4 address. It's done transparently for outgoing connections, ensuring the correct response traffic is routed to your computer, but if you wish to accept incoming connections some configuration is necessary.
+
+The NAT manager can be configured as follows:
+
+```js
+const node = await Libp2p.create({
+  config: {
+    nat: {
+      description: 'my-node', // set as the port mapping description on the router, defaults the current libp2p version and your peer id
+      enabled: true, // defaults to true
+      gateway: '192.168.1.1', // leave unset to auto-discover
+      externalIp: '80.1.1.1', // leave unset to auto-discover
+      ttl: 7200, // TTL for port mappings (min 20 minutes)
+      keepAlive: true, // Refresh port mapping after TTL expires
+      pmp: {
+        enabled: false, // defaults to false
+      }
+    }
+  }
+})
+```
+
+##### Browser support
+
+Browsers cannot open TCP ports or send the UDP datagrams necessary to configure external port mapping - to accept incoming connections in the browser please use a WebRTC transport.
+
+##### UPnP and NAT-PMP
+
+By default under nodejs libp2p will attempt to use [UPnP](https://en.wikipedia.org/wiki/Universal_Plug_and_Play) to configure your router to allow incoming connections to any TCP transports that have been configured.
+
+[NAT-PMP](http://miniupnp.free.fr/nat-pmp.html) is a feature of some modern routers which performs a similar job to UPnP. NAT-PMP is disabled by default, if enabled libp2p will try to use NAT-PMP and will fall back to UPnP if it fails.
+
+#### Configuring protocol name
+
+Changing the protocol name prefix can isolate default public network (IPFS) for custom purposes. 
+
+```js
+const node = await Libp2p.create({
+  config: {
+    protocolPrefix: 'ipfs' // default
+  }
+})
+/*
+protocols: [
+  "/ipfs/id/1.0.0", // identify service protocol (if we have multiplexers)
+  "/ipfs/id/push/1.0.0", // identify service push protocol (if we have multiplexers)
+  "/ipfs/ping/1.0.0", // built-in ping protocol
+]
+*/
+```
+
+
 ## Configuration examples
 
 As libp2p is designed to be a modular networking library, its usage will vary based on individual project needs. We've included links to some existing project configurations for your reference, in case you wish to replicate their configuration:

+
+## Types
+
+Most of the type definitions in the libp2p configuration were `any` or were not included before this release. This might cause breaking changes on upstream projects relying on the previous provided types, as well as to libp2p modules implemented by the libp2p community.
+
+## API
+
+### Core API
+
+`libp2p.dialProtocol` does not accept empty or null protocols returning a connection anymore and `dial` must be used instead.
+
+```js
+const connection = await libp2p.dialProtocol(peerId)
+```
+
+**After**
+
+```js
+const connection = await libp2p.dial(peerId)
+```
+
+### Connection Manager Options
+
+We updated the connection manager options naming in `libp2p@0.29` but kept it backward compatible until now.
+
+**Before**
+
+```js
+const node = await Libp2p.create({
+  connectionManager: {
+    minPeers: 0
+  }
+})
+```
+
+**After**
+
+```js
+const node = await Libp2p.create({
+  connectionManager: {
+    minConnections: 0
+  }
+})
+```
+
+You can see full details on how to configure the connection manager [here](https://github.com/libp2p/js-libp2p/blob/master/doc/CONFIGURATION.md#configuring-connection-manager).
+
+### Dialer and Keychain components
+
+Internal property names to create a libp2p `Dialer` and `Keychain` were updated to reflect the properties naming in the libp2p configuration. These are internal modules of libp2p core and should not impact most of the users, but as it is possible to use them separately here follow the changes:
+
+***Before**
+
+```js
+const dialer = new Dialer({
+  transportManager,
+  peerStore,
+  concurrency,
+  perPeerLimit,
+  timeout,
+  resolvers,
+  addressSorter
+})
+
+const keychain = new Keychain(datastore, {
+  passPhrase
+})
+```
+
+**After**
+
+```js
+this.dialer = new Dialer({
+  transportManager,
+  peerStore,
+  maxParallelDials,
+  maxDialsPerPeer,
+  dialTimeout,
+  resolvers,
+  addressSorter
+})
+
+const keychain = new Keychain(datastore, {
+  pass
+})
+```
+

+
+One of the main changes in this new release is the update to `multiaddr@9.0.0`. This should also be updated in upstream projects to avoid several multiaddr versions in the bundle and to avoid potential problems when libp2p interacts with provided outdated multiaddr instances.

+
+Libp2p uses a datastore implementation for Peerstore persistence and for the DHT state. While libp2p defaults to a datastore implementation, it can receive any implementation of a datastore compliant with the [interface-datastore](https://github.com/ipfs/js-ipfs-interfaces/tree/master/packages/interface-datastore) via its configuration.
+
+In this release, we updated to `interface-datastore@6.0.0`. As a result, libp2p users relying on a configured datastore should update it to a compliant implementation for updating libp2p.

 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).
+With this 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. Once new peers are discovered, their known data is stored in the peer's PeerStore.

-## 3. Where to find other Peer Discovery Mechanisms
+## 3. Pubsub based Peer Discovery
+
+For this example, we need [`libp2p-pubsub-peer-discovery`](https://github.com/libp2p/js-libp2p-pubsub-peer-discovery/), go ahead and `npm install` it. You also need to spin up a set of [`libp2p-relay-servers`](https://github.com/libp2p/js-libp2p-relay-server). These servers act as relay servers and a peer discovery source.
+
+In the context of this example, we will create and run the `libp2p-relay-server` in the same code snippet. You can find the complete solution at [3.js](./3.js).
+
+You can create your libp2p nodes as follows:
+
+```js
+const Libp2p = require('libp2p')
+const TCP = require('libp2p-tcp')
+const Mplex = require('libp2p-mplex')
+const { NOISE } = require('@chainsafe/libp2p-noise')
+const Gossipsub = require('libp2p-gossipsub')
+const Bootstrap = require('libp2p-bootstrap')
+const PubsubPeerDiscovery = require('libp2p-pubsub-peer-discovery')
+
+const createNode = async (bootstrapers) => {
+  const node = await Libp2p.create({
+    addresses: {
+      listen: ['/ip4/0.0.0.0/tcp/0']
+    },
+    modules: {
+      transport: [TCP],
+      streamMuxer: [Mplex],
+      connEncryption: [NOISE],
+      pubsub: Gossipsub,
+      peerDiscovery: [Bootstrap, PubsubPeerDiscovery]
+    },
+    config: {
+      peerDiscovery: {
+        [PubsubPeerDiscovery.tag]: {
+          interval: 1000,
+          enabled: true
+        },
+        [Bootstrap.tag]: {
+          enabled: true,
+          list: bootstrapers
+        }
+      }
+    }
+  })
+
+  return node
+}
+```
+
+We will use the `libp2p-relay-server` as bootstrap nodes for the libp2p nodes, so that they establish a connection with the relay after starting. As a result, after they establish a connection with the relay, the pubsub discovery will kick in and the relay will advertise them.
+
+```js
+const relay = await createRelayServer({
+  listenAddresses: ['/ip4/0.0.0.0/tcp/0']
+})
+console.log(`libp2p relay starting with id: ${relay.peerId.toB58String()}`)
+await relay.start()
+const relayMultiaddrs = relay.multiaddrs.map((m) => `${m.toString()}/p2p/${relay.peerId.toB58String()}`)
+
+const [node1, node2] = await Promise.all([
+  createNode(relayMultiaddrs),
+  createNode(relayMultiaddrs)
+])
+
+node1.on('peer:discovery', (peerId) => {
+  console.log(`Peer ${node1.peerId.toB58String()} discovered: ${peerId.toB58String()}`)
+})
+node2.on('peer:discovery', (peerId) => {
+  console.log(`Peer ${node2.peerId.toB58String()} discovered: ${peerId.toB58String()}`)
+})
+
+;[node1, node2].forEach((node, index) => console.log(`Node ${index} starting with id: ${node.peerId.toB58String()}`))
+await Promise.all([
+  node1.start(),
+  node2.start()
+])
+```
+
+If you run this example, you will see the other peers being discovered.
+
+```bash
+> node 3.js
+libp2p relay starting with id: QmW6FqVV6RsyoGC5zaeFGW9gSWA3LcBRVZrjkKMruh38Bo
+Node 0 starting with id: QmezqDTmEjZ5BfMgVqjSpLY19mVVLTQ9bE9mRpZwtGxL8N
+Node 1 starting with id: QmYWeom2odTkm79DzB68NHULqVHDaNDqHhoyqLdcV1fqdv
+Peer QmezqDTmEjZ5BfMgVqjSpLY19mVVLTQ9bE9mRpZwtGxL8N discovered: QmW6FqVV6RsyoGC5zaeFGW9gSWA3LcBRVZrjkKMruh38Bo
+Peer QmYWeom2odTkm79DzB68NHULqVHDaNDqHhoyqLdcV1fqdv discovered: QmW6FqVV6RsyoGC5zaeFGW9gSWA3LcBRVZrjkKMruh38Bo
+Peer QmYWeom2odTkm79DzB68NHULqVHDaNDqHhoyqLdcV1fqdv discovered: QmezqDTmEjZ5BfMgVqjSpLY19mVVLTQ9bE9mRpZwtGxL8N
+Peer QmezqDTmEjZ5BfMgVqjSpLY19mVVLTQ9bE9mRpZwtGxL8N discovered: QmYWeom2odTkm79DzB68NHULqVHDaNDqHhoyqLdcV1fqdv
+```
+
+Taking into account the output, after the relay and both libp2p nodes start, both libp2p nodes will discover the bootstrap node (relay) and connect with it. After establishing a connection with the relay, they will discover each other.
+
+This is really useful when running libp2p in constrained environments like a browser. You can run a set of `libp2p-relay-server` nodes that will be responsible for both relaying websocket connections between browser nodes and for discovering other browser peers.
+
+## 4. 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. For example [libp2p-kad-dht](https://github.com/libp2p/js-libp2p-kad-dht) can be used for peer discovery. An example how to configure it to enable random walks can be found [here](https://github.com/libp2p/js-libp2p/blob/v0.28.4/doc/CONFIGURATION.md#customizing-dht).

+## 0. Set up the example
+
+Before moving into the examples, you should run `npm install` on the top level `js-libp2p` folder, in order to install all the dependencies needed for this example. In addition, you will need to install the example related dependencies by doing `cd examples && npm install`. Once the install finishes, you should move into the example folder with `cd pubsub`.

 ## 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).

+### Webrtc-direct example
+
+An example that uses [js-libp2p-webrtc-direct](https://github.com/libp2p/js-libp2p-webrtc-direct) for connecting
+nodejs libp2p and browser libp2p clients. To run the example:
+
+## 0. Run a nodejs libp2p listener
+
+When in the root folder of this example, type `node listener.js` in terminal. You should see an address that listens for
+incoming connections. Below is just an example of such address. In your case the suffix hash (`peerId`) will be different.
+
+```bash
+$ node listener.js 
+Listening on:
+/ip4/127.0.0.1/tcp/9090/http/p2p-webrtc-direct/p2p/QmUKQCzEUhhhobcNSrXU5uzxTqbvF1BjMCGNGZzZU14Kgd
+```
+
+## 1. Prepare a browser libp2p dialer
+Confirm that the above address is the same as the field `list` in `public/dialer.js`:
+```js
+    peerDiscovery: {
+      [Bootstrap.tag]: {
+        enabled: true,
+        // paste the address into `list`
+        list: ['/ip4/127.0.0.1/tcp/9090/http/p2p-webrtc-direct/p2p/QmUKQCzEUhhhobcNSrXU5uzxTqbvF1BjMCGNGZzZU14Kgd']
+      }
+    }
+```
+
+## 2. Run a browser libp2p dialer
+When in the root folder of this example, type `npm run dev` in terminal. You should see an address where you can browse
+the running client. Open this address in your browser. In console
+logs you should see logs about successful connection with the node client. In the output of node client you should see
+a log message about successful connection as well.
