 ## Usage
 
+**IMPORTANT NOTE**: We are currently on the way of migrating all our `libp2p` modules to use `async await` and `async iterators`, instead of callbacks and `pull-streams`. As a consequence, when you start a new libp2p project, we must check which versions of the modules you should use. For now, it is required to use the modules using callbacks with `libp2p`, while we are working on getting the remaining modules ready for a full migration. For more details, you can have a look at [libp2p/js-libp2p#266](https://github.com/libp2p/js-libp2p/issues/266).

 ### API
 
+**IMPORTANT NOTE**: All the methods listed in the API section that take a callback are also now Promisified. Libp2p is migrating away from callbacks to async/await, and in a future release (that will be announced in advance), callback support will be removed entirely. You can follow progress of the async/await endeavor at https://github.com/ipfs/js-ipfs/issues/1670.

 #### Create a Node - `Libp2p.createLibp2p(options, callback)`
 
 > Behaves exactly like `new Libp2p(options)`, but doesn't require a PeerInfo. One will be generated instead
