title: git pull changes to sub branch
body: <p>I've cloned a repository called A and created a new branch called Li.<br>
  Now someone updated A's master branch and I've pulled the changes to my master branch using:</p>
  
  <pre><code>git checkout master
  git pull origin master
  </code></pre>
  
  <p>Now I want to update my branch (Li) with the changes.
  How do I do it?</p>
  
  <p>In adittion, after updating my local branch with the changes, I need to update the remote Li branch with the changes as well, right?
  Do I do it by using: </p>
  
  <pre><code>git checkout Li
  git push origin Li 
  </code></pre>
