Git flow
Methodology for working with git. It defines a standard of rules and branches for their use e.g. master, develop, feature, hotfix, release. The methodology streamline project work and enable more effective team collaboration.
Master
stores the stable version of the project
Develop

What is a working copy in git
A working copy in git is a local copy of a repository on the developer’s computer. It contains project files and a history of changes. It doesn’t affect the repository itself until changes are committed
Service directory (index)
This is the intermediate between the working copy and the repository.
This is where changes are tracked before committing.
Files needed in the next commit are added, files not needed are deleted.
Git init
creating a new repository
Git clone
cloning an existing repository on the computer
Git add
add files to the service directory
Git commit
fixing changes to the repository
