There are a few steps the MantisBT team requires of contributors and developers when accepting code submissions. The user needs to configure Git to know their full name (not a screen name) and an email address they can be contacted at (not a throwaway address).
To set up your name and email address with Git, run the following commands, substituting your own real name and email address:
git config --global user.name "John Smith"
git config --global user.email "jsmith@mantisbt.org"
Optionally, you may want to configure Git to use terminal colors when displaying file diffs and other information, and also alias certain Git actions to shorter phrases to reduce typing:
git config --global color.diff "auto"
git config --global color.status "auto"
git config --global color.branch "auto"
git config --global alias.st "status"
git config --global alias.di "diff"
git config --global alias.co "checkout"
git config --global alias.ci "commit"
