title: How to commit a change in git when git commit opens Nano?
body: <p>I'm new to git and I'm trying to commit my first changes on a Windows machine. However, when I type in <code>$git commit</code> it takes me to a different screen than any online tutorials show or than what is mentioned in <a href="https://git-scm.com/book/en/v2" rel="noreferrer">Pro Git</a>. No online searching yields an explanation of how to use this screen, either.</p>
  
  <p>The screen looks like this: <a href="https://i.stack.imgur.com/qobmR.png" rel="noreferrer"><img src="https://i.stack.imgur.com/qobmR.png" alt="The git commit screen I&#39;m having trouble with"></a></p>
  
  <p>I have tried every key on the keyboard, but nothing seems to actually <strong>do</strong> the commit. Also there are all these little help options in green at the bottom of the screen that seem to be giving commands, but when I press the buttons they show it just types them into the commit message. What are those help options and how do I use them?</p>
  
  <p>Everyone else seems to be using something called "vim" which I believe I chose not to install when installing Git because I thought the Windows console was fine.</p>
  
  <p><em>So how do I actually commit and what are those green commands at the bottom of the screen?</em> Thanks!</p>
