Git

Git is an open source software which is used for version control by Developers.

To make it simpler to understand, think of it as a time machine for code, you can revert back to a specific version of code at any time and make different branches to code on different features and in different teams.

Why use Git tho?

• You can time travel!
• You can make Parallel Universes!
• Work in a team

Basic Terminology

Git Repository

Repository is simply a folder which has .git file in it. .git file is used to define the states of file in the directory you’re working in. For now, we don’t need to get into the details.

Three Stages

All the files in a git repo have one of these three states: modified, staged and committed

• Modified: files you’ve changed but aren’t yet committed to the database.
• Staged: These files will be committed in the next snapshot
• Committed: These files are safely stored in the git snapshots.
