 There are many more, but this list should be a good starting point.
 For more information on how to work with Atom's official packages, see [Contributing to Atom Packages](https://github.com/atom/atom/blob/master/docs/contributing-to-packages.md).

 Each community package has its own repository too, and you should be able to find it in Settings > Packages for the packages you installed and contribute there.
 
 ### Design Decisions
 
-When we make a significant decision in how we maintain the project and what we can or cannot support, we will be documenting them in the [atom/design-decisions repository](https://github.com/atom/design-decisions). If you have a question around how we do things, check to see if it is documented there. If it is *not* documented there, please open a new topic on [Discuss, the official Atom message board](https://discuss.atom.io) and ask your question.
