This is a godsend! I was going to do it myself but you've done it before me. Some minor points that I think will improve the docs is:

1. Put a colon between @annotation and its name (eg. @class Class declaration annotation -> `@class: Class declaration).
2. Sort the list under "Annotations" so that @ preceeds/suceeds "Array/Table/String literal annotation".

These are just suggestions, so no pressure!

@takase1121, thanks for your suggestions, I would gladly implement them, but since there's no interest from the author, I kind of lost the interest to spend any more time on it... If you would like, feel free to push your changes on top of this branch, though.
