Good to know

Patterns do not remove files Git already tracks, and they do not erase secrets from commit history. To stop tracking a file that is already committed, remove it from the index first. Matching follows gitignore rules: the last matching line wins, a leading / anchors to the root, a trailing / matches folders only, and a file inside an ignored folder cannot be re-included. Character classes and escapes are supported; check unusual patterns with git check-ignore.

Using Gitignore Builder

Combine practical Node, Python, build-output, OS and environment-file presets with your own ignore patterns.
