 ### 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).

-- `peerBook`: instance of [PeerBook][] that contains the [PeerInfo][] of known peers. Optional.
-- `options`: Object containing custom options for the bundle.
-
-#### `libp2p.start(callback)`
-
-> Start the libp2p Node.
-
-`callback` is a function with the following `function (err) {}` signature, where `err` is an Error in case starting the node fails.
-
-#### `libp2p.stop(callback)`
-
-> Stop the libp2p Node.
-
-`callback` is a function with the following `function (err) {}` signature, where `err` is an Error in case stopping the node fails.
-
-#### `libp2p.dial(peer [, protocol, callback])`
-
-> Dials to another peer in the network.
-
-- `peer`: can be an instance of [PeerInfo][], [PeerId][] or [multiaddr][]
-- `protocol`: String that defines the protocol (e.g '/ipfs/bitswap/1.1.0')

-
-#### `libp2p.hangUp(peer, callback)
-
-> Closes an open connection with a peer, graciously.
-
-- `peer`: can be an instance of [PeerInfo][], [PeerId][] or [multiaddr][]

-
-> Handle new protocol
-
-- `protocol`: String that defines the protocol (e.g '/ipfs/bitswap/1.1.0')
-- `handlerFunc`: Function with signature `function (protocol, conn) {}`
-- `matchFunc`: Function for matching on protocol (exact matching, semver, etc). Default to exact match.
-
-#### `libp2p.unhandle(protocol)
-
-> Stop handling protocol
-
-- `protocol`: String that defines the protocol (e.g '/ipfs/bitswap/1.1.0')
-
-#### `libp2p.on('peer:discovery', (peer) => {})`
-
-> Peer has been discovered.
-
-- `peer`: instance of [PeerInfo][]
-
-#### `libp2p.on('peer:connect', (peer) => {})`

+THe libp2p implementation in JavaScript is a work in progress. As such, there's 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.
