There is very little that is hard with managing your source code on your local workstation.

To commit any changes, you type in:

  git commit -a -m "thing that I changed"

To branch, it's:

  git checkout -b newbranch

To switch back to the master branch, you just type in:

  git commit -a -m "changes made on branch"
  git checkout master

To merge in that branch, should you so wish to do so, then you type in:

  git merge newbranch

What is exactly so hard about that?
