git - how?
draft…
Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.
“Talk is cheap. Show me the code.”
– Linus Torvalds
History
On 3 April 2005, Linus Torvalds began the development of git, after many Linux kernel developers gave up access to BitKeeper. Just 3 days after, on 6 April, Torvalds announced the project. And the next day, it became self-hosting.
On 26 July 2005, Linus Torvalds turned over git’s project maintenance to Junio Hamano. Hamano is the project’s core maintainer since.
Workflow
The basic/usual git workflow is the following:
- Create/clone a git repository, all your work is done in this Working Directory.
- Once your work reaches your goal, your changes are added to the Staging Area.
- Now your Staging Area contains everything you want to commit, you can save changes to the git repository.
