@ -252,49 +192,15 @@ Returns an `obj` of the form
 - `obj.pubKey: String` - The public key in protobuf format, encoded in 'base64'
 - `obj.privKey: String` - The private key in protobuf format, encoded in 'base 64'
 ### `marshal(excludePrivateKey)`
 Returns a protocol-buffers encoded version of the id, public key and, if `excludePrivateKey` is not set, the private key.
 ### `marshalPubKey()`
 Returns a protobuf of just the public key, compatible with `libp2p-crypto` (unlike `marshal` above).
 For example:
 ```js
 const crypto = require('libp2p-crypto')
 PeerId.create({ bits: 256, keyType: 'ed25519' }).then( pid => {
  let pk = crypto.keys.unmarshalPublicKey(pid.marshalPubKey())
  // your code here
 }
 ```
 ### `toPrint()`
-Returns the Peer ID as a printable string without the `Qm` prefix.
+Alias for `.toJSON()`.
 Example: `<peer.ID xxxxxx>`
 ### `equals(id)`
 Returns `true` if the given PeerId is equal to the current instance.
 - `id` can be a PeerId or a Buffer containing the id
 ### `isEqual(id)`
 **Deprecation Notice**: Use [`equals`](#equalsid), `isEqual` will be removed in 0.14.0.
 - `id` can be a PeerId or a Buffer containing the id
 ## Others
 ### `isPeerId(id)`
 Returns `true` if the given id is an instance of PeerId
 - `id` should be an instance of PeerId
