Verify contents and format of track documentation

[kytrinyx]

Each language track has documentation in the docs/ directory, which gets included on the site
on each track-specific set of pages under /languages.

We've added some general guidelines about how we'd like the track to be documented in exercism/exercism#3315
which can be found at https://github.com/exercism/exercism.io/blob/master/docs/writing-track-documentation.md

Please take a moment to look through the documentation about documentation, and make sure that
the track is following these guidelines. Pay particularly close attention to how to use images
in the markdown files.

Lastly, if you find that the guidelines are confusing or missing important details, then a pull request
would be greatly appreciated.

@kytrinyx is this still valid? The links above seem to go somewhere else in the new site.

[kytrinyx]

Hm, no the links are wrong. It would be really nice to ensure that the logged-out page for Kotlin is great, though: http://exercism.io/tracks/kotlin

[mikegehard]

Gotcha...I'll take a look at the logged out version of http://exercism.io/tracks/kotlin and make it great. :-)
