Commit

From your first local commit to a tagged release -- Git and GitHub habits that stick for makers and developers.

Commit teaches Git and GitHub from zero to everyday confidence. You will install and configure Git, master the working tree and the index, branch and undo safely, use pull requests and Actions, and version a real ESP32 project -- firmware, PCB and docs -- through its first release.

What you will learn

• Install and configure Git on Windows, macOS and Linux
• The working tree, index and commit history as a practical mental model
• Branches, merges, rebases and conflict resolution without panic
• Safe undo with restore, revert, reset and reflog
• Remotes, SSH or HTTPS auth, pull requests and open source contribution habits
• GitHub Actions for firmware builds, SemVer tags and GitHub Releases
• Hardware repos, Git LFS awareness and a RoomNode v1.0.0 release checklist

Who it is for

Makers, students and beginner to intermediate developers. Assumes comfort with a terminal or willingness to learn one. Starts from zero Git knowledge. Hardware readers may know PlatformIO or KiCad without knowing remotes or pull requests.
