[jgrapht-users] guidelines for new contributors

[John S. <js...@gm...>]

We've been receiving a lot of pull requests from new contributors lately,
which is great.  To explain what to expect during the process of getting
contributions incorporated into the codebase, we've written up some wiki
pages:

https://github.com/jgrapht/jgrapht/wiki/Become-a-Contributor

https://github.com/jgrapht/jgrapht/wiki/How-to-make-your-first-%28code%29-contribution

https://github.com/jgrapht/jgrapht/wiki/Contributor-Guidelines

So if you're thinking of sending us a pull request for a contribution
you've been working on, please give these a read through first.  Thanks!
