A rookery is a place where your ideas can grow. Rookeries are collections of files, entirely local and owned by you, with no vendor or cloud lock-in. When rookeries are compiled with Rheo, every idea can be rendered as a webpage, a PDF, or an EPUB, at any time. This is true also for collections of ideas, ranging from a set of ideas with the same tags to your entire rookery.

For an example of a rookery in code, see the rookery documentation source.
