Honeybadger is your favorite error tracker for Ruby. When your app raises an
exception we notify you with all the context you need to fix it.

The Honeybadger CLI provides tools for interacting with Honeybadger via the
command line.

If you need support, please drop us a line: support@honeybadger.io

WELCOME
