This covers all the principal features of Ruby In Steel Developer (which will be available next week) and Ruby In Steel Personal (Release Candidate 1 is available now; the final release - which will incorporate a few quite minor changes to RC1 - will be available in February).
The manual is an illustrated 66-page PDF guide to the editing, debugging, project management and IntelliSense features (the latter in the Developer edition only) provided by Ruby In Steel for both Ruby and Rails development.
