A Git repository (or repo for short) contains all of the project les and the entire revision history. You’ll take an ordinary folder of les (such as a website’s root folder), and tell Git to make it a repository. This creates a .git subfolder, which contains all of the Git metadata for tracking changes.
On Unix-based operating systems such as macOS, les and folders that start with a period (.) are hidden, so you will not see the .git folder in the macOS Finder unless you show hidden les, but it’s there! You might be able to see it in some
code editors.
TIP: On macOS you can show or hide invisible les by hitting Cmd–Shift-Period(.)
Initialize a Git Repo
