The document discusses open source projects and how everyone can participate in them. It reveals that there is no real distinction between those developing a project ("we") and outsiders ("them"), but rather that individuals play various roles within and across projects. It encourages the reader to get involved by choosing a role like contributor, tester, or documenter, and provides tips on how to start, such as learning source control, unit testing, blogging, and creating your own gems or plugins. The overarching message is that permission is not needed and the reader should not keep any secrets, but rather get involved in an open source project of their choosing.
