DA Umbrella is a self-evolving recursive umbrella system that powers the dA Umbrella.

The umbrella has a goal of making it easy to organize and demonstrate the things I craft. It is hugely inspired by Devine Lu Linvega's amazing work on XXIIVV.

The outer side of the umbrella consists of two levels of nodes and a blog. Nodes can be public or private. The Implementation Notes is an example of a sub-node.

The inner side of the umbrella is an iOS/macOS app that builds content for the outer side.
