 # Description
 
-An IPFS Peer Id is based on a sha256 hash of the peer public key, using [multihash](https://github.com/jbenet/multihash)
+Generate, import, and export PeerIDs, for use with [IPFS](https://github.com/ipfs/ipfs).
+
+A Peer ID is the SHA-256 [multihash](https://github.com/multiformats/multihash) of a public key.
 
 The public key is a base64 encoded string of a protobuf containing an RSA DER buffer. This uses a node buffer to pass the base64 encoded public key protobuf to the multihash for ID generation.
 
+# Example
 
-# Usage
-
-### In Node.js through npm
+```JavaScript
+const PeerId = require('peer-id')
 
+PeerId.create({ bits: 1024, keyType: 'rsa' }, (err, id) => {
+  if (err) { throw err }
+  console.log(JSON.stringify(id.toJSON(), null, 2))
+})
+```
 ```bash
-> npm install --save peer-id
+{
+  "id": "Qma9T5YraSnpRDZqRR4krcSJabThc8nwZuJV3LercPHufi",
+  "privKey": "CAAS4AQwggJcAgEAAoGBAMBgbIqyOL26oV3nGPBYrdpbv..",
+  "pubKey": "CAASogEwgZ8wDQYJKoZIhvcNAQEBBQADgY0AMIGJAoGBAMBgbIqyOL26oV3nGPBYrdpbvzCY..."
+}
 ```
 
-```javascript
+# Installation
+
+## npm
+
+```sh
+> npm i peer-id
+```
+
+# Setup
+
+## Node.js
+
+```js
 const PeerId = require('peer-id')
 ```
 
-### In the Browser through Webpack
+## Browser: Browserify, Webpack, other bundlers
 
-Follow our [webpack config](/webpack.config.js) example.
+The code published to npm that gets loaded on require is in fact a ES5
+transpiled version with the right shims added. This means that you can require
+it and use with your favourite bundler without having to adjust asset management
+process.
 
-### In the Browser through browserify
-
-> **WIP** Doesn't work out yet
-
-### In the Browser through `<script>` tag
-
-Make the [peer-id.js](/dist/peer-id.js) available through your server and load it using a normal `<script>` tag, this will export the `PeerId` object, such that:
-
-```JavaScript
-const Id = PeerId
+```js
+const PeerId = require('peer-id')
 ```
 
-#### Gotchas
+## Browser: `<script>` Tag
 
-You will need to use Node.js `Buffer` API compatible, if you are running inside the browser, you can access it by `PeerId.Buffer` or you can install Feross's [Buffer](https://github.com/feross/buffer).
+Loading this module through a script tag will make the `PeerId` obj available in
+the global namespace.
 
-### Creating a new Id
-
-```
-const PeerId = require('ipfs-peer')
-
-// Create a new Id
-const id = PeerId.create()
-
-// Recreate an Id from Hex string
-const id = PeerId.createFromHexString(str)
-
-// Recreate an Id from a Buffer
-const id = PeerId.createFromBytes(buf)
-
-// Recreate an B58 String
-const id = PeerId.createFromB58String(str)
-
-// Recreate from a Public Key
-const id = PeerId.createFromPubKey(pubKey)
-
-// Recreate from a Private Key
-const id = PeerId.createFromPrivKey(privKey)
+```html
+<script src="https://unpkg.com/peer-id/dist/index.min.js"></script>
+<!-- OR -->
+<script src="https://unpkg.com/peer-id/dist/index.js"></script>
 ```
 
-### Exporting an Id
+# API
 
-```
-// Print friendly format
-id.toPrint() // returns an object with id, privKey and pubKey in hex format
-
-// Export to an hex string
-id.toHexString()
-
-// Export to Buffer
-id.toBytes() (same as id.id)
-
-// Export to a B58 string
-id.toB58String()
+```js
+const PeerId = require('peer-id')
 ```
 
-### Id format
+## Create
+
+### `new PeerId(id[, privKey, pubKey])`
+
+- `id: Buffer` - The multihash of the publick key as `Buffer`
+- `privKey: RsaPrivateKey` - The private key
+- `pubKey: RsaPublicKey` - The public key
+
+The key format is detailed in [libp2p-crypto](https://github.com/libp2p/js-libp2p-crypto).
+
+### `create([opts], callback)`
+
+Generates a new Peer ID, complete with public/private keypair.
+
+- `opts: Object`: Default: `{bits: 2048, keyType: 'rsa'}`
+- `callback: Function`
+
+Calls back `callback` with `err, id`.
+
+## Import
+
+### `createFromHexString(str)`
+
+Creates a Peer ID from hex string representing the key's multihash.
+
+### `createFromBytes(buf)`
+
+Creates a Peer ID from a buffer representing the key's multihash.
+
+### `createFromB58String(str)`
+
+Creates a Peer ID from a Base58 string representing the key's multihash.
+
+### `createFromPubKey(pubKey)`
+
+- `publicKey: Buffer`
+
+Creates a Peer ID from a buffer containing a public key.
+
+### `createFromPrivKey(privKey)`
+
+- `privKey: Buffer`
+
+Creates a Peer ID from a buffer containing a private key.
+
+### `createFromJSON(obj)`
+
+- `obj.id: String` - The multihash encoded in `base58`
+- `obj.pubKey: String` - The public key in protobuf format, encoded in `base64`
+- `obj.privKey: String` - The private key in protobuf format, encoded in `base64`
+
+## Export
+
+### `toHexString()`
+
+Returns the Peer ID's `id` as a hex string.
 
 ```
-id.pubKey   // Buffer containing the Public Key
-id.privKey  // Buffer containing the Private Key
-id.id       // Buffer containing the multihash
