Git is the version control software, allowing savepoints to be made when developing code
Version control is helpful when developing code, especially in a team, to help prevent developers working on outdated code
Staging files is the act of preparing files to be pushed back to the main repository, on Github.
This is a simple process and only takes one command.
In Terminal, open the correct folder
Type "git add -A" to prepare all files in the folder to be pushed
If successful, the terminal will display a new line with no text
The files are now staged, ready to be committed.
