Time machine?
Time machine
- git log
- git diff
- git diff
- git checkout
- git checkout -b
- History of changes
- Current changes
- Changes:
to now - Restore version
- Create a 'branch'
Installation: git shell & gui:s
Built-in: git gui & gitk
IDE git tools (built-in git shell)
3rd Party: IDE git tools
If that doesn't fix it, git.txt contains the phone number of a friend of mine who understands git. Just wait through a few minutes of 'It's really pretty simple, just think of branches as...' and eventually you'll learn the commands that will fix everything
