title: How to add a git repo in package.json file
body: <p>I have an app where I didn't add its repository in <code>package.json</code> while doing <code>npm init</code>.</p>
  <p>Now I want to add repo in the <code>package.json</code> file, but couldn't find helpful solutions for me.</p>
  <p>Also, I found repository url's ending like this <code>.git</code> but my repo address is simply this <a href="https://github.com/sonyzach/usfm-validator" rel="nofollow noreferrer">https://github.com/sonyzach/usfm-validator</a></p>
