Do you want to begin coding for NavCoin but don’t have a specific improvement in mind? Here are a few ideas:
Fix existing issues
The issue tracker for each repository is the best place to find a useful way to contribute to NavCoin. Before starting to write any patches for issues you find, you may want to comment on the issue to make sure nobody else is already working on it.
NavCoin’s various softwares are covered by many tests, but patches that improve test coverage are always welcome and are a great way to build familiarity with the codebase. See the documentation about automated testing.
