through <em>Merge Requests</em> for review.</p><p>The rudimentary idea behind aims for changes to be present on a separate branch
that is supposedly <em>merged</em> into the default branch. Till then changes can be reviewed
on <em>Merge Request</em> and additional changes may be made based on the reviews. Once
the changes satisfy requirements, the merge request is merged.</p><h2class="anchor anchorWithStickyNavbar_LWe7"id="tutorial">Tutorial<ahref="#tutorial"class="hash-link"aria-label="Direct link to Tutorial"title="Direct link to Tutorial"></a></h2><blockquote><p>Use this tutorial only for bonus assignments <strong>made by your tutors</strong> or in case
