How to prepare a Unity project for git? [duplicate]

Answer 1

Since Unity 4.3 you also have to enable External option from preferences, so full setup process looks like:

1. Enable External option in Unity → Preferences → Packages → Repository
2. Switch to Hidden Meta Files in Editor → Project Settings → Editor → Version Control Mode
3. Switch to Force Text in Editor → Project Settings → Editor → Asset Serialization Mode
4. Save scene and project from File menu

Note that the only folders you need to keep under source control are Assets and ProjectSettigns.
