title: Update forked project on GitHub
body: <p>Let's say a repository from which I clone (and only read-only for me) is:</p>
  
  <pre><code>git@github.com:secret_project/dev.git  branch: dev
  </code></pre>
  
  <p>I forked project and URL:</p>
  
  <pre><code>git@github.com:secret_user/Dde.git
  </code></pre>
  
  <p>(Which I have full access to: read+write)</p>
  
  <p>But someone updated <code>git@github.com:secret_project/dev.git</code> from another forked version.</p>
  
  <p>Let's say file changed on</p>
  
  <pre><code>git@github.com:secret_project/dev.git  (test.txt)
  content:
  hi!
  </code></pre>
  
  <p>But my forked project has <code>test.txt</code> file with content:</p>
  
  <pre><code>hi
  </code></pre>
  
  <p>So how do I update the forked project locally and in my repository?</p>
  
  <p>Which commands should I use? And please make an example with my showed repositories...</p>
