title: How can I most simply reorganize a git repository?
body: <p>I would like to reorganize a git repo to manage multiple projects.
  I have one like </p>
  
  <pre><code>my-org
  |--cool-repo
     |--file-one
     |--file-two
  </code></pre>
  
  <p>And I would like to make it like</p>
  
  <pre><code>my-org
  |--cool-repo
     |--project-one
        |--file-one
        |--file-two
     |--project-two
  </code></pre>
  
  <p>I've read some of the git docs, but I am unsure about what commands I should study.  I do not need to merge code, or, net, delete anything.  </p>
  
  <p>I do not want to break anything.</p>
  
  <p>As my team starts second, third, and later projects, I'd like to organize "subdirectories" or "subprojects" (I am unsure of the term to use) to hold docs related to these added projects.</p>
  
  <p>What should I do, or where can I best resume investigation?</p>
  
  <p>Thanks!</p>
