You can donate your time in code, either by sending it to me for review, or cloning the git repository and publishing your changes (to be eventually merged back into my tree). You can donate your time in testing, documentation, artwork, indexing, etc. Or, if you don't feel that you possess the time or skills required for the above forms of donation, you can donate money instead.
