+### Install
+
+> npm install ipns
+
+## Usage
+
+#### Create record
+
+```js
+const ipns = require('ipns')
+
+ipns.create(privateKey, value, sequenceNumber, lifetime, (err, entryData) => {
+  // your code goes here
+});
+```
+
+#### Validate record
+
+```js
+const ipns = require('ipns')
+
+ipns.validate(publicKey, ipnsEntry, (err) => {
+  // your code goes here
+  // if no error, the record is valid
+});
+```
+
+#### Embed public key to record
+
+> Not available yet
+
+#### Extract public key from record
+
+> Not available yet
+
+#### Datastore key
+
+```js
+const ipns = require('ipns')
+
+ipns.getLocalKey(peerId);
+```
+
+Returns a key to be used for storing the ipns entry locally, that is:
+
+```
+/ipns/${base32(<HASH>)}
+```
+
+#### Marshal data with proto buffer
+
+```js
+const ipns = require('ipns')
+
+ipns.create(privateKey, value, sequenceNumber, lifetime, (err, entryData) => {
+  // ...
+  const marshalledData = ipns.marshal(entryData)
+  // ...
+});
+```
+
+Returns the entry data serialized.
+
+#### Unmarshal data from proto buffer
+
+```js
+const ipns = require('ipns')
+
+const data = ipns.unmarshal(storedData)
+```
+
+Returns the entry data structure after being serialized.
+
+## API
+
+#### Create record
+
+```js
+
+ipns.create(privateKey, value, sequenceNumber, lifetime, [callback]);
+```
+
+Create an IPNS record for being stored in a protocol buffer.
+
+- `privateKey` (`PrivKey` [RSA Instance](https://github.com/libp2p/js-libp2p-crypto/blob/master/src/keys/rsa-class.js)): key to be used for cryptographic operations.
+- `value` (string): ipfs path of the object to be published.
+- `sequenceNumber` (Number): number representing the current version of the record.
+- `lifetime` (string): lifetime of the record (in milliseconds).
+- `callback` (function): operation result.
+
+`callback` must follow `function (err, ipnsEntry) {}` signature, where `err` is an error if the operation was not successful. `ipnsEntry` is an object that contains the entry's properties, such as:
+
+```js
+{
+  value: '/ipfs/QmWEekX7EZLUd9VXRNMRXW3LXe4F6x7mB8oPxY5XLptrBq',
+  signature: Buffer,
+  validityType: 0,
+  validity: '2018-06-27T14:49:14.074000000Z',
+  sequence: 2
+}
+```
+
+#### Validate record
+
+```js
+
+ipns.validate(publicKey, ipnsEntry, [callback]);
+```
+
+Validate an IPNS record previously stored in a protocol buffer.
+
+- `publicKey` (`PubKey` [RSA Instance](https://github.com/libp2p/js-libp2p-crypto/blob/master/src/keys/rsa-class.js)): key to be used for cryptographic operations.
+- `ipnsEntry` (Object): ipns entry record (obtained using the create function).
+- `callback` (function): operation result.
+
+`callback` must follow `function (err) {}` signature, where `err` is an error if the operation was not successful. This way, if no error, the validation was successful.
+
+#### Datastore key
+
+```js
+ipns.getDatastoreKey(peerId);
+```
+
+Get a key for storing the ipns entry in the datastore.
+
+- `peerId` (`Uint8Array`): peer identifier.
+
+#### Marshal data with proto buffer
+
+```js
+const marshalledData = ipns.marshal(entryData)
+});
+```
+
+Returns the entry data serialized.
+
+- `entryData` (Object): ipns entry record (obtained using the create function).
+
+#### Unmarshal data from proto buffer
+
+```js
+const data = ipns.unmarshal(storedData)
+```
+
+Returns the entry data structure after being serialized.
+
+- `storedData` (Buffer): ipns entry record serialized.
