How does it work?

GitHub displays commits in the contribution history graph. Contribution pushes a bunch of commits with a custom date using git commit --date <date>. It bundles multiple commits on a single day to achieve a darker pixel in the graph.

The GitHub contribution graph is 52 × 7 pixels and shows up to five shades for activity. This app automatically limits the colors and dimensions of your input image to match these restrictions. Use the preview subcommand if you're not feeling lucky.

Warning: you cannot remove contribution activity on GitHub unless you delete a project, so you probably want to push to a project specifically created for this purpose. Contributions to secret projects may also be shown, depending on your GitHub settings.

Contribution uses your default SSH settings and global Git user, which can be tested with ssh -T git@github.com and git config --global user.email. If you prefer to use another identity, set GIT_SSH_COMMAND='ssh -i /other/id_rsa' and git config --global user.email "other@example.org".
