Basecamp is a Web-based project management application that focuses on communication and collaboration, not the charts, graphs, and statistics used in traditional project management.
To use the Choreos in this bundle you'll need a Basecamp account, which you can get at http://basecamphq.com/signup. You'll also need a Basecamp API token, which can be found by logging into your account, clicking the My Info link in the upper-right corner, then clicking Show Your Tokens at the bottom (under Authentication Tokens).
The Basecamp API also uses Basic Authentication to authorize requests, but all the Basecamp Choreos generate a Basic Authorization token automatically. Just specify your username and password and the Choreos will do the rest.
