title: How to upgrade Gatsby starter blog deployed on Netlify via GitHub?
body: <p>Some weeks ago I deployed a blog based on the <a href="https://github.com/gatsbyjs/gatsby-starter-blog" rel="nofollow noreferrer">Gatsby blog starter</a> on Netlify.</p>
  
  <p>I'm doing the <em>Git Repository Setup</em> via GitHub (<a href="https://www.gatsbyjs.org/docs/hosting-on-netlify#git-repository-setup" rel="nofollow noreferrer">https://www.gatsbyjs.org/docs/hosting-on-netlify#git-repository-setup</a>).</p>
  
  <p>How do I upgrade? How do I keep track of upstream changes?</p>
  
  <p>Today I looked around with <a href="https://en.wikipedia.org/wiki/Diff" rel="nofollow noreferrer">diff</a>. For my particular blog, it seems it's something I could do manually.</p>
  
  <p>At the moment, it seems it would suffice to account for 2 things:</p>
  
  <ul>
  <li><p>The changes to <em>src/components/seo.js</em> of <a href="https://github.com/gatsbyjs/gatsby-starter-blog/commit/74aed704ad706969945e7864a00d8adac1bd17e2" rel="nofollow noreferrer">74aed704ad706969945e7864a00d8adac1bd17e2</a>.</p></li>
  <li><p>The changes to <em>package.json</em>.</p></li>
  </ul>
  
  <p>By <em>doing it manually</em>, I mean I would just edit <em>seo.js</em> and <em>package.json</em> replicating the changes at <a href="https://github.com/gatsbyjs/gatsby-starter-blog" rel="nofollow noreferrer">https://github.com/gatsbyjs/gatsby-starter-blog</a>.</p>
  
  <p>Is there another way of doing this?</p>
