I did some training at our last Mozilla workweek that covered the major areas of Servo and had some simple exercises to get you started in each of them:<p><a href="https:&#x2F;&#x2F;drive.google.com&#x2F;file&#x2F;d&#x2F;0B9-EBhw4XiWEOWFfc0NiUkk5Tjg&#x2F;view?usp=sharing" rel="nofollow">https:&#x2F;&#x2F;drive.google.com&#x2F;file&#x2F;d&#x2F;0B9-EBhw4XiWEOWFfc0NiUkk5Tjg...</a><p>Servo has polyrepo style (many separate source repositories), as opposed to the monorepo style of other browsers. So, it&#x27;s not just the `components` directory, but many of the ~140 other Cargo crates (<a href="https:&#x2F;&#x2F;crates.io&#x2F;" rel="nofollow">https:&#x2F;&#x2F;crates.io&#x2F;</a>) and raw GitHub packages that come together to form Servo. I have a &quot;deliverable&quot; for Q4 to improve our documentation situation and explain how it all is put together, though this gist is an awesome start!
