- Art (ranges from 2D icons, textures to 3D models)
- Map development
- Writing documentation
How to contribute
If you want to help with programming, a good first step is joining the IRC-channel #0ad-dev on QuakeNet IRC. Usually there are some developers in IRC who can help you get started. Next, most development work (code review) is done on Phabricator. One can look around here to see what things are currently in the process of being added to the game. For further information, check out GettingStartedProgrammers.
Most of the communication around art is done on the art forums, and one should probably start there.
