title: How do I add Ruby to the PATH variable on Windows?
body: <p>I have Ruby installed, but I still need to add it to the PATH variable. I found something online for how to manually add it using the command line:</p>
  
  <pre><code>set PATH=C:\Ruby200-x64\bin;%PATH%
  </code></pre>
  
  <p>But before I try it, I want to be sure it's not going to overwrite what's currently in the PATH variable. (I have no experience with this stuff so I don't know what to expect).</p>
  
  <p>Thanks in advance for your help!</p>
