+#Contributing to BitBurner
+
+##In General
+The game is made better because the community as a whole speaks up about
+ways to improve the game. Here's some of the ways you can make your voice
+heard:
+ - [Discord](https://discordapp.com)
+   There is a dedicated Discord instance set up for more free-form chats
+   between all members of the community. Regular players, heavy scripters,
+   BitBurner contributors, and everyone in between can be found on the
+   server.
+ - [Github Issues](https://github.com/danielyxie/bitburner/issues)
+   Although the term "issues" can have a negative connotation, they are a
+   means of communicating with the community. A new Issue can be a
+   interesting new feature that you feel would improve the game. It could be
+   an unexpected behavior within the game. Or because the game is about
+   scripting perhaps there is something that is conflicting with the
+   browser's Javascript interaction. So please do not be afraid to open a
+   [new issue](https://github.com/danielyxie/bitburner/issues/new).
+
+##As a Developer
+To contribute to BitBurner code, you will need to have
+[NodeJS](https://nodejs.org) installed. When installing NodeJS, a utility
+called `npm` is installed as well.
+
+Before submitting your code for a pull request, please try to follow these
+rules:
+ - Work in a branch forked from `dev` to isolate the new code
+ - Ensure you have latest from the [game's main
+   repository](danielyxie/bitburner@dev)
+ - Rebase your branch if necessary
+ - Run the game locally to test out your changes
+ - When submitting the pull request, make sure that the base fork is
+   _danielyxie/bitburner_ and the base is _dev_.
+
+##As a Documentor
+To contribute to BitBurner documentation, you will need to have Python
+installed, along with [Sphinx](http://www.sphinx-doc.org).
