If you are not familiar with version control systems, I suggest you start with Subversion to learn the basic concepts and get used to the workflow. Git is very powerful, but it can be a little more complicated at first if you have never worked with an SCM tool before.
The easiest way to get the SVN repository is to use Apache to access the repository via http or https. You can find guides around the world on configuring Apache + SVN (examples here and here ).
