+## Getting Started
+
+### Prerequisites
+
+Make sure you have installed all of the following prerequisites on your development machine:
+
+- Git - [Download & Install Git](https://git-scm.com/downloads). OSX and Linux machines typically have this already installed.
+- Node.js - [Download & Install Node.js](https://nodejs.org/en/download/) and the npm package manager.

+The IPFS implementation in JavaScript needs your help! There are a few things you can do right now to help out:
+
+Read the [Code of Conduct](https://github.com/ipfs/community/blob/master/code-of-conduct.md) and [JavaScript Contributing Guidelines](https://github.com/ipfs/community/blob/master/CONTRIBUTING_JS.md).
+
+- **Check out existing issues** The [issue list](https://github.com/ipfs/js-ipfs/issues) has many that are marked as ['help wanted'](https://github.com/ipfs/js-ipfs/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc+label%3A%22help+wanted%22) or ['difficulty:easy'](https://github.com/ipfs/js-ipfs/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc+label%3Adifficulty%3Aeasy) which make great starting points for development, many of which can be tackled with no prior IPFS knowledge
+- **Look at the [IPFS Roadmap](https://github.com/ipfs/roadmap)** This are the high priority items being worked on right now
+- **Perform code reviews** More eyes will help
+  a. speed the project along
+  b. ensure quality, and
+  c. reduce possible future bugs.
+- **Add tests**. There can never be enough tests.
+- **Join the [Weekly Core Implementations Call](https://github.com/ipfs/team-mgmt/issues/992)** it's where everyone discusses what's going on with IPFS and what's next
