git status
	tells us the status of our working directory
	compares wooden and cardboard box
		difference will be in red
			- doesnt just track files, also changes in the files
			- this means if you made changes to a file when the file is not in the wooden box, there is discrepancy between
			the version of this in cardboard box, and the current version.
			- in this case, you need to add the file again.
	compares cardboard and metal box
		difference will be in green

git config --global user.name, user.email, add colour etc
	do it once for every device

==== Git Summary ====

Commit:
	(v) finalise changes in repo
	(n) the final change in the repo

add and commit to be done separately for reasons

Basic git workflow:

1. Change
2. Stage (Add)
3. Finalse (Commit)

==== Section 3: Time travelling and multiverse ====

git checkout [commit-id]
	- switches workspace to the version at that commit-id
	- even if you enter the commit-id of the master, git will not show master.
	It's just paranoid xD

git checkout master
	goes directly to most recent commit
	when you do this, git will prompt to ask if you want to discard changes you made "in the past", if any

git log --all
	shows all changes
