What is branching in git ?

Branches must be understood as simple bookmarks in the timeline of commit. Contrary to other tools like Subversion, where a branch is a fork of the main timeline, here they are just pointers.

So considering this timeline of commit in a main branch

A -- B -- C (main)

Considering that HEAD is on C, then doing the following command to create a branch will simply create a “pointer” to C named feature-x

git branch feature-x

it creates this :

A -- B -- C
			\
			(main)
			(feature-x)

What is HEAD ?

How do I change from one branch to another ?

What is the difference between a local and remote branch ?
