title: How to checkout from git
body: <p>So far, being the only person on a project, I have been copying/pasting my project folders and renaming them (Ver1, Ver2, Ver3, etc.) as a version control scheme.
  Now I am trying to switch to Git.</p>
  
  <p>This is what I did:<br>
  I initialized a <code>.git</code> folder and added the first version to the Git repository.
  Then I added all other versions as commits to the git repository and tagged them.
  So now I have all the versions in the master branch and as tags.</p>
  
  <p>My question is:<br>
  How can I (I do not know if checkout is the right word) grab any version from the Git repository and put it in an arbitrary folder without switching branches (or any other operation Git may think it has to do)? Just simply copying a version (any version) from Git to a folder without any connection between the Git repository and the folder?</p>
