Version control for game projects

Games break in surprising ways. Version control with Git keeps a history of your project, so you can go back to the last version that worked. Game projects need two extra habits.

First, add a .gitignore file that tells Git to skip the folders your engine generates: Unity's Library and Temp, Godot's .godot folder, or Unreal's Intermediate, Saved and Binaries. The engine rebuilds these automatically, and tracking them causes conflicts.

Second, use Git LFS (Large File Storage) for big binary files such as textures, audio and models, so the repository stays fast. Commit whenever something works, with a short message. This makes team jams possible and protects you before risky changes later.
