 IPFS implementation in JavaScript is a work in progress. As such, there's a few things you can do right now to help out:
 
   * Go through the modules below and **check out existing issues**. This would be especially useful for modules in active development. Some knowledge of IPFS may be required, as well as the infrastructure behind it - for instance, you may need to read up on p2p and more complex operations like muxing to be able to help technically.
-  * **Perform code reviews**. Most of this has been developed by @diasdavid, which means that more eyes will help a) speed the project along b) ensure quality and c) reduce possible future bugs.

   * Take a look at go-ipfs and some of the planning repositories or issues: for instance, the libp2p spec [here](https://github.com/ipfs/specs/pull/19). Contributions here that would be most helpful are **top-level comments** about how it should look based on our understanding. Again, the more eyes the better.
   * **Add tests**. There can never be enough tests.
   * **Contribute to the [FAQ repository](https://github.com/ipfs/faq/issues)** with any questions you have about IPFS or any of the relevant technology. A good example would be asking, 'What is a merkledag tree?'. If you don't know a term, odds are, someone else doesn't either. Eventually, we should have a good understanding of where we need to improve communications and teaching together to make IPFS and IPN better.
