-### 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).

 # Chat example with libp2p
+
+This example creates a simple chat app in your terminal.
+
+## 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. Type a message in either window and hit _enter_
+4. Tell yourself secrets to your hearts content!

+# 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
