message: Update base README with a tour of the repo
diff: Prague is investigating and prototyping key design questions around interactive documents and MUIs.
  -The [server](./server) folder contains a set of legacy prototypes around a collaborative canvas. As well as MUIs that load within the browser or within an enlightened host.
  +We're currently in the middle of [Sprint 2](./doc/sprints/sprint2/readme.md). Highlights include rich text, git based storage, and intelligent services in an augmentation loop.
  -[Routerlicious](./routerlicious) contains our latest prototype around new approaches to collaborative objects as well as a server backend to enable them with minimal COGS.
  +## Source Code Overview
  +
  +[Routerlicious](./routerlicious) contains our latest prototype around new approaches to collaborative objects as well as a server backend to enable them with minimal COGS. This is probably where you want to start.
  +
  +[Historian](./historian) provides a REST API to git repositories. The API is similar to that exposed by GitHub but can be used in local development.
  +
  +[Augmentation](./augmentation) provides a set of augmentation loop services exposed via Docker containers.
  +
  +[Collab-Editor](./collab-editor) is a Visual Studio Code plugin that enables collaborative editing of source code.
  +
  +[Experiments](./experiments) contain experimental code or other prototypes.
  +
  +[Doc](./doc) provides documentation for the project.
  +
  +[Gitssh](./gitssh) is a git ssh server client container.
  +
  +[Intelligence](./intelligence) contains a starter container for developing Python based intelligent services.

  +[legacy](./legacy) folder contains a set of legacy prototypes around a collaborative canvas. As well as MUIs that load within the browser or within an enlightened host.
  +
  +## Build Server
  +
  +We make use of https://hub.docker.com/r/microsoft/vsts-agent/ for building all of the source in this project.
  -The other folders contain past prototypes.
