 ## Create
 
-### PeerId.create()
+### `new PeerId(id[, privKey, pubKey])`
 
-Generates a new Peer ID, complete with public/private keypair. A Peer ID has the
+- `id: Buffer` - The multihash of the publick key as `Buffer`
-following properties:
+- `privKey: RsaPrivateKey` - The private key
+- `pubKey: RsaPublicKey` - The public key
 
-- `pubKey` - Buffer containing the public key bytes
+The key format is detailed in [libp2p-crypto](https://github.com/libp2p/js-libp2p-crypto).
-- `privKey` - Buffer containing the private key bytes
+
-- `id` - Buffer containing the multihash bytes
+### `create([opts])`
+
+Generates a new Peer ID, complete with public/private keypair.
+
+- `opts: Object`: Default: `{bits: 2048, keyType: 'rsa'}`
+
+Returns `Promise<PeerId>`.
 
 ## Import
 
-### PeerId.createFromHexString(str)
+### `createFromHexString(str)`
 
 Creates a Peer ID from hex string representing the key's multihash.
 
-### PeerId.createFromBytes(buf)
+Returns `PeerId.
+
+### `createFromBytes(buf)`
 
 Creates a Peer ID from a buffer representing the key's multihash.
 
-### PeerId.createFromB58String(str)
+Returns `PeerId`.
+
+### `createFromB58String(str)`
+
 Creates a Peer ID from a Base58 string representing the key's multihash.
 
-### PeerId.createFromPubKey(pubKey)
+Returns `PeerId`.
+
+### `createFromPubKey(pubKey)`
+
+- `publicKey: Buffer`
 
 Creates a Peer ID from a buffer containing a public key.
 
-### PeerId.createFromPrivKey(privKey)

+
+### `createFromPrivKey(privKey)`
+
+- `privKey: Buffer`
 
 Creates a Peer ID from a buffer containing a private key.
 
+Returns `Promise<PeerId>`.
+
+### `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`
+
+Returns `Promise<PeerId>`.
+
+### `createFromProtobuf(buf)`
+
+`buf` is a protocol-buffers encoded PeerId (see `marshal()`)
+
 ## Export
