title: How can collaborators push their changes to my repo in GitHub
body: <ol>
  <li><p>First I have created one project in Eclipse and committed to my GitHub using below commands:<pre><code>git init
  git add .
  git commit -m "first commit"
  git remote add origin URI of my repo
  git push -u origin master</code></pre></p></li>
  <li><p>Then I modified one file in Eclipse and committed to GitHub from Eclipse through creating remote and giving the remote URI of the repo.</p></li>
  <li>I added my team member through add collaborator.</li>
  <li>Then he downloaded my project and made a change in a file in Eclipse.</li>
  </ol>
  
  <p>Now, how can he push that modified file to my GitHub repository from within Eclipse?</p>
  
  <p>We have done one thing. He created a remote and gave the URI of my repo. But still we are unable to commit that file.</p>
