+# How to Contribute
+
+The best way to get started is to read through the `Getting Started` and `Example`
+sections before having a look through the open [issues](https://github.com/js-platform/filer/issues).
+Some of the issues are marked as `good first bug`, but feel free to contribute to
+any of the issues there, or open a new one if the thing you want to work on isn't
+there yet. If you would like to have an issue assigned to you, please send me a
+message and I'll update it.
+
+## Setup
+
+The Filer build system is based on [grunt](http://gruntjs.com/). To get a working build system
+do the following:
+
+```
+npm install
+npm install -g grunt-cli
+```
+
+You can now run the following grunt tasks:
+* `grunt check` will run [JSHint](http://www.jshint.com/) on your code (do this before submitting a pull request) to catch errors
+* `grunt develop` will create a single file version of the library for testing in `dist/idbfs.js`
+* `grunt release` like `develop` but will also create a minified version of the library in `dist/idbfs.min.js`
+
+Once you've done some hacking and you'd like to have your work merged, you'll need to
+make a pull request. If you're patch includes code, make sure to check that all the
+unit tests pass, including any new tests you wrote. Finally, make sure you add yourself
+to the `AUTHORS` file.
+
+## Tests
+
+Tests are writting using [Jasmine](http://pivotal.github.io/jasmine/). You can run the tests
+in your browser by opening the `tests` directory. You can also run them
+[here](http://js-platform.github.io/idbfs/tests/).
+
+## Communication
+
+If you'd like to talk to someone about the project, you can reach us on irc.mozilla.org in the
+mofodev channel. Look for "ack" or "humph".
