Welcome to the developers' group of the rootpy project. As a rootpy developer, this group should provide an easy way to exchange ideas, discuss current issues, and update the other developers on your current progress.
The rootpy project collaboration on github can be found here:
To begin development on rootpy, first fork the desired repository to your github account. When your contribution is ready, submit a pull request (PR) for the other developers to review and provide feedback. You may also submit a PR for development that is still a work in progress, in which case you should prefix the PR title with "WIP: ". For a contribution that is ready to be merged into the main rootpy repository you should prefix the PR title with "MRG: ".
Happy hacking!
