Git cycle
- Clone to make a working copy or init plus other actions creates a new local repo
- In working copy edit files or make new ones
- If needed update local copy with pull to pick up changes by others
- Build/run/test/view/render/read
- Add the name of changed files that are ready to be committed (if don’t use add git won’t keep track of changes)
- Commit you changes to local repo (add message, keeps record of it locally)
- If changes aren’t ready go back to 2
- Push committed changes to remote repo
- Go to step 2
Commit
- each commit results in the creation of a new snapshot
- commit is not the same as push
