<h3 id="_recommendation">Recommendation</h3>
<div class="paragraph">
<p>All examples in class target <a href="https://pop.system76.com/">Pop!_OS 21.04</a>.
Essentially, this is a <a href="http://releases.ubuntu.com/21.04/">Ubuntu 21.04 LTS (Hirsute Hippo)</a> Linux distribution.
There are many more such Ubuntu derivates, choose one of your liking: <a href="https://linuxmint.com/">Linux Mint</a>, <a href="https://elementary.io/">Elementary OS</a>, <a href="https://neon.kde.org/">KDE Neon</a>, etc.</p>
</div>
<div class="paragraph">
<p>Since all sessions contain hands-on exercises, we recommend that you have such a Linux version installed on a computer.
(In case you decide to run another operating system, we cannot provide too much support for these during class.) The recommended setup is to have such a Linux installed natively on your machine.</p>
</div>
<div class="paragraph">
<p>Find installation instructions <a href="https://github.com/itu-devops/lecture_notes/blob/master/sessions/session_00/README.adoc">session_00/README.adoc</a>.</p>
</div>
<div class="paragraph">
<p>Note, we do not have any experiences with the new M1-based Macs.
Neither do we have access to one of these.
Consequently, likely many of the technologies that we demonstrate will have issues on these computers and we won’t be able to support you much.</p>
