You can find documentation at chartjs.org/docs. The markdown files that build the site are available under /docs. Please note - in some of the json examples of configuration you might notice some liquid tags - this is just for the generating the site html, please disregard.

When reporting bugs or issues, if you could include a link to a simple jsbin or similar demonstrating the issue, that'd be really helpful.
