+```
+
+This provides a well defined interface for creating and interacting with an IPFS repo.
+
+## Install
+
+### npm
+
+```sh
+> npm install ipfs-repo
+```
+
+### Use in Node.js
+
+```js
+var IPFSRepo = require('ipfs-repo')
+```
+
+### Use in a browser with browserify, webpack or any other bundler
+
+```js
+var IPFSRepo = require('ipfs-repo')
+```
+
+### Use in a browser Using a script tag
+
+Loading this module through a script tag will make the `IpfsRepo` obj available in the global namespace.
+
+```html
+<script src="https://unpkg.com/ipfs-repo/dist/index.min.js"></script>
+<!-- OR -->
+<script src="https://unpkg.com/ipfs-repo/dist/index.js"></script>
+```
+
+## Usage
+
+Example:
+
+```js
+const Repo = require('ipfs-repo')
+const repo = new Repo('/tmp/ipfs-repo')
+
+repo.init({ cool: 'config' }, (err) => {
+  if (err) {
+    throw err
+  }
+
+  repo.open((err) => {
+    if (err) {
+      throw err
+    }
+
+    console.log('repo is ready')
+  })
+})
+```
+
+This now has created the following structure, either on disk or as an in memory representation:
+
+```
+├── blocks
+│   ├── SHARDING
+│   └── _README
+├── config
+├── datastore
+└── version
+```
+
+## API
+
+### Setup
+
+#### `new Repo(path[, options])`
+
+Creates an IPFS Repo.
+
+Arguments:
+
+* `path` (string, mandatory): the path for this repo
+* `options` (object, optional): may contain the following values
+  * `lock` (string, defaults to `"fs"` in Node.js, `"memory"` in the browser): what type of lock to use. Lock has to be acquired when opening.
+  * `storageBackends` (object, optional): may contain the following values, which should each be a class implementing the [datastore interface](https://github.com/ipfs/interface-datastore#readme):
+    * `root` (defaults to [`datastore-fs`](https://github.com/ipfs/js-datastore-fs#readme) in Node.js and [`datastore-level`](https://github.com/ipfs/js-datastore-level#readme) in the browser). Defines the back-end type used for gets and puts of values at the root (`repo.set()`, `repo.get()`)
+    * `blocks` (defaults to [`datastore-fs`](https://github.com/ipfs/js-datastore-fs#readme) in Node.js and [`datastore-level`](https://github.com/ipfs/js-datastore-level#readme) in the browser). Defines the back-end type used for gets and puts of values at `repo.blocks`.
+    * `datastore` (defaults to [`datastore-level`](https://github.com/ipfs/js-datastore-level#readme)). Defines the back-end type used as the key-valye store used for gets and puts of values at `repo.datastore`.
+
+```js
+const repo = new Repo('path/to/repo')
+```
+
+#### `repo.init (callback)`
+
+Creates the necessary folder structure inside the repo.
+
+#### `repo.open (callback)`
+
+Locks the repo.
+
+#### `repo.close (callback)`
+
+Unlocks the repo.
+
+#### `repo.exists (callback)`
+
+Tells whether this repo exists or not. Calls back with `(err, bool)`.
+
+### Repos
+
+Root repo:
+
+#### `repo.put (key, value:Buffer, callback)`
+
+Put a value at the root of the repo.
+
+* `key` can be a buffer, a string or a [Key](https://github.com/ipfs/interface-datastore#keys).
+
+#### `repo.get (key, callback)`
+
+Get a value at the root of the repo.
+
+* `key` can be a buffer, a string or a [Key](https://github.com/ipfs/interface-datastore#keys).
+* `callback` is a callback function `function (err, result:Buffer)`
+
+[Blocks](https://github.com/ipfs/js-ipfs-block#readme):
+
+#### `repo.blocks.put (block:Block, callback)`
+
+* `block` should be of type [Block](https://github.com/ipfs/js-ipfs-block#readme).
+
+#### `repo.blocks.putMany (blocks, callback)`
+
+Put many blocks.
+
+* `block` should be an array of type [Block](https://github.com/ipfs/js-ipfs-block#readme).
+
+#### `repo.blocks.get (cid, callback)`
+
+Get block.
+
+* `cid` is the content id of [type CID](https://github.com/ipld/js-cid#readme).
+* `callback` is a callback function `function (err, result:Buffer)`
+
+Datastore:
+
+#### `repo.datastore`
+
+This is contains a full implementation of [the `interface-datastore` API](https://github.com/ipfs/interface-datastore#api).
+
+
+### Utils
+
+#### `repo.config`
+
+Instead of using `repo.set('config')` this exposes an API that allows you to set and get a decoded config object, as well as, in a safe manner, change any of the config values individually.
+
+##### `repo.config.set(key:string, value, callback)`
+
+Set a config value. `value` can be any object that is serializable to JSON.
+
+* `key` is a string specifying the object path. Example:
+
+```js
+repo.config.set('a.b.c', 'c value', (err) => {
+  if (err) { throw err }
+  repo.config.get((err, config) => {
+    if (err) { throw err }
+    assert.equal(config.a.b.c, 'c value')
+  })
+})
+```
+
+##### `repo.config.get(value, callback)`
+
+Set the whole config value. `value` can be any object that is serializable to JSON.
+
+##### `repo.config.get(key:string, callback)`
+
+Get a config value. `callback` is a function with the signature: `function (err, value)`, wehre the `
+value` is of the same type that was set before.
+
+* `key` is a string specifying the object path. Example:
+
+```js
+repo.config.get('a.b.c', (err, value) => {
+  if (err) { throw err }
+  console.log('config.a.b.c = ', value)
+})
+```
+
+##### `repo.config.get(callback)`
+
+Get the entire config value. `callback` is a function with the signature: `function (err, configValue:Object)`.
+
+#### `repo.config.exists(callback)`
+
+Whether the config sub-repo exists. Calls back with `(err, bool)`.
+
+#### `repo.version`
+
+##### `repo.version.get (callback)`
+
+Gets the repo version.
+
+##### `repo.version.set (version:number, callback)`
+
+Sets the repo version
+
+#### `repo.apiAddr`
+
+#### `repo.apiAddr.get (callback)`
+
+Gets the API address.
+
+#### `repo.apiAddr.set (value, callback)`
+
+Sets the API address.
+
+* `value` should be a [Multiaddr](https://github.com/multiformats/js-multiaddr) or a String representing a valid one.
