What is Github?

A code hosting platform for version control and collaboration, where developers can store and share their projects. 

Some Github Terminology

Some commonly used terms that we'll be using in class:

https://help.github.com/articles/github-glossary/ 

• Repository -The location where all the files for a particular project are stored

• Fork  - Creating a personal copy of someone else's project.

• Clone - Making a copy of the repo into your local computer.  This repo copy lives on your computer instead of on website’s server.  

• Pull Requests - When you fork a repo, make a revision to the project and want to be recognized by the original developer, you can create a pull request, so the author of the original repository can see your work and decide whether or not to accept it into the official project.

What is Git?

• British Slang - A foolish or worthless person (especially a man)

• Version control system created by Linus Torvalds that allows you and the team to keep track of every modification to the code

• Version control allows for easy collaboration with other developers

• git branch - lists all existing branches
• git checkout branch - switches into a different branch
• git branch branchName - creates a new branch
• git checkout -b branchName - adds and switches into the new branch
• git fetch - downloads all changes from the remote but doesn't integrate into HEAD
• git pull - downloads all changes and directly integrates into HEAD
• git merge branch - merges updated changes into current branch
