Sumatra is an open-source project under GPLv3 license. If you want to join Sumatra development, the process is simple:
- write a patch against the latest sources
- create a new bug in issue tracker and attach the patch.
- make sure to describe what the patch is trying to fix and why (not every change is good)
- we'll review the patch and either incorporate it into sources (if we think it's good) or describe how it needs to be improved
Getting the sources
You'll need Visual Studio 2010 or 2008 to build. A free Express Edition for C++ will work.
