While at EclipseCon 2011 Miles Parker and I decided to conduct our own Buckminster BoF. Yes, this year's conference was all about Maven/Tycho builds, but we though that Buckminster had its own advantages that people might find beneficial to them.
For the BoF I created a very simple Buckminster build that build a very simple RCP application, in fact the RCP is so simple that it's just a window. The point of this is just to show a bare bone Buckminster build and give user instant gratification in actually building something quick. In fact, this bare bone build can be used for more complicated project because the beauty of Buckminster is that it does not need any more information that you already have - features and plugins.
If you are just starting out with Buckminster checkout Ralf Ebert's article as a starting point, get familiar with Bucky Book and of course visit Buckminster forum as it has vast amount of information that other people and myself were faced while working with Buckminster.

Also, here are notes about Buckminster that were generated while implementing it for our build, hopefully these will be useful to someone.
