The introduction explains what it is, but here are some highlights:

- Each Ruby exception is a sneaky creature which could pop up in your Ruby apps.

- The documentation (which is in-progress) is supplemented by docs from Ruby core and standard lib.

- The errors on the Bestiary page are ordered by attack scores which are calculated from Honeybadger data (so these are the errors which are occurring the most in your apps).

- We've finished 3 characters so far, and will be adding more in the coming weeks/months.

We hope you like it!
