title: How do I replace a zip file in a forked repository
body: <p>I need to update a zip file forked from another user's github repository.</p>
  
  <p>I have a repository forked from <a href="https://github.com/k2zia/AD985XSPI" rel="nofollow noreferrer">https://github.com/k2zia/AD985XSPI</a> that contains only two files, a readme, and a zip file (AD985XSPI.zip).  The zip file is an Arduino library that does not contain a "libraries.properties" file, a requirement that has been added since the time the original repository was created.  I downloaded the zip file, unzipped it, added a "libraries.properties" file, rezipped, and now need to replace the existing zip file in my repository.</p>
  
  <p>I am unclear on how to accomplish this task.</p>
