+#### `Domain data types`
+
+A set of data types are exposed directly from the IPFS instance under `ipfs.types`. That way you're not required to import/require the following.

 #### `Utility functions`
 
 Adding to the methods defined by [`interface-ipfs-core`](https://github.com/ipfs/interface-ipfs-core), `js-ipfs-api` exposes a set of extra utility methods. These utility functions are scoped behind the `ipfs.util`.

 ### Callbacks and Promises
 
 If you do not pass in a callback all API functions will return a `Promise`. For example:
