<h2>What is OctoPi?</h2>
<p>
OctoPi is a <a href="http://www.raspberrypi.org/">Raspberry Pi</a>
distribution for 3D printers. Out of the box it includes:
</p>
<ul>
<li>
the <a href="http://octoprint.org">OctoPrint</a> host software including all
its dependencies and preconfigured with webcam and slicing support,
</li>
<li>
<a href="https://github.com/jacksonliam/mjpg-streamer">mjpg-streamer</a> for
live viewing of prints and timelapse video creation with support
for USB webcams and the Raspberry Pi camera and
</li>
<li>
<a href="https://github.com/Ultimaker/CuraEngine">CuraEngine 15.04</a> for direct slicing on your
Raspberry Pi.
</li>
</ul>
<h2>Where can I get OctoPi?</h2>
<p>
You can download the latest stable build via this button:
</p>
<p>
<a class="btn btn-primary btn-large" href="https://octopi.octoprint.org/latest"><i class="icon-download-alt icon-large"></i> Download OctoPi 0.16.0</a>
</p>
<p>
<small>MD5sum of the .zip: <code>52c855c9bcc88fd3bf81bbe8e58a2e4c</code></small>
</p>
<p>
Compatible with Raspberry Pi 3B+, 3A+, A, B, A+, B+, B2, <strong>3</strong><sup><a href="#footnote-1-text" class="footnote" id="footnote-1">1)</a></sup>, Zero and Zero W<sup><a href="#footnote-2-text" class="footnote" id="footnote-2">2)</a></sup>
</p>
<p>
Additional mirrors can be found here:
</p>
<ul>
<li><a href="https://gnethomelinux.com/OctoPi/nightly/">Mirror #1</a> (also includes nightly builds)</li>
</ul>
<h2>How do I set it up?</h2>
<ol>
<li>
Download the image via the button above.
</li>
<li>
Unzip the zipped image and install the contained <code>.img</code> file to an sd card
<a href="https://www.raspberrypi.org/documentation/installation/installing-images/README.md">like any other Raspberry Pi image</a>
</li>
<li>
Configure your WiFi by editing <code>octopi-network.txt</code>
on the root of the flashed card when using it like a thumb drive
</li>
<li>
Boot the Pi from the card
</li>
<li>
Log into your Pi via SSH (it is located at <code>octopi.local</code>
<a href="https://learn.adafruit.com/bonjour-zeroconf-networking-for-windows-and-linux/overview">if your computer supports bonjour</a>
or the IP address assigned by your router), default username
is "pi", default password is "raspberry". <strong>Change the
password</strong> using the <code>passwd</code> command. You do not need
to expand the filesystem, current versions of OctoPi do this automatically.
</li>
</ol>
<p>
OctoPrint is located at <a href="http://octopi.local">http://octopi.local</a>
and also at <a href="https://octopi.local">https://octopi.local</a>.
Since the SSL certificate is self signed (and generated upon first boot),
you will get a certificate warning at the latter location.
</p>
<p>
If a USB webcam or the Raspberry Pi camera is detected, MJPG-streamer
will be started automatically as webcam server. OctoPrint on
OctoPi ships with correctly configured stream and snapshot URLs
pointing at it. If necessary, you can reach it under
<code>http://octopi.local/webcam/?action=stream</code> and SSL
respectively, or directly on its configured port 8080:
<code>http://octopi.local:8080/?action=stream</code>.
</p>
<p>
CuraEngine 15.04 is installed and OctoPrint ships pre-configured with
the correct path to utilize it for on-board-slicing. Just import
a Cura Slicing Profile in OctoPrint's settings and start slicing
directly on your Pi.
</p>
<h2>Are there further resources to get going?</h2>
<p>
Yes!

<h2>I want to build my own version of OctoPi</h2>
<p>
