+The following are functions and values exposed to all apps in their \`app.js\` or \`handler.js\`.  Most
+of these are asynchronous, returning a \`Promise\` that will be resolved when the call completes, unless
+noted otherwise.
+
+This is all a work in progess. These are liable to change without warning.  Feedback is welcome.
+
+The exposed functions in this API balance multiple competing needs:
+ * The surface area of the exposed API ought to be fairly minimal.  If something can be implemented entirely app-side, that is
+   generally preferred over building it into the core.
+ * Everything is built on this API.  Ideally the admin app, the SSB app, and the editor all use standard API exposed to all
+   apps, with appropriate permission guards in place making it so that only trusted apps do potentially destructive operations.
+   There will be some things here that aren't necessarily general use to support what's required.
+
+If you are looking at the [Tilde Friends source code](https://www.tildefriends.net/~cory/releases/),

 ## Synchronizing Data
-So now you're discovering other clients on the local network, connecting, performing
-a secret handshake, and making remote procedure calls over box streams.  The next step
-is to start synchronizing feeds over the network.  The goal, after all, is to author
-messages in your local append-only log and have them show up in distant clients, or
-vice versa.
+
+... `ebt.replicate` or `createHistoryStream` ...

+# Tilde Friends Vision
+[Back to index](#index)
+
+Tilde Friends is a tool for making and sharing.
+
+It is both a peer-to-peer social network client, participating in Secure
+Scuttlebutt, and an environment for creating and running web applications.
+
+## Why
+
+This is a thing that I wanted to exist and wanted to work on.  No other reason.
+There is not a business model.  I believe it is interesting and unique.
+
+## Goals
+1. Make it **easy and fun** to run all sorts of web applications.
+
+2. Provide **security** that is easy to understand and protects your data.
+
+3. Make **creating and sharing** web applications accessible to anyone with a
+   browser.
+
+## Ways to Use Tilde Friends
+1. **Social Network User**: This is a social network first.  You are just here,
+   because your friends are.  Or you like how we limit your message length or
+   short videos or whatever the trend is.  If you are ambitious, you click links
+   and see interactive experiences (apps) that you wouldn't see elsewhere.
+
+2. **Web Visitor**: You get links from a friend to meeting invites, polls, games,
+   lists, wiki pages, ..., and you interact with them as though they were
+   cloud-hosted by a megacorporation.  They just work, and you don't think twice.
+
+3. **Group leader**: You host or use a small public instance, installing apps for
+   a group of friends to use as web visitors.
+
+4. **Developer**: You like to write code and make or improve apps for fun or to
+   solve problems.  When you encounter a Tilde Friends app on a strange server,
+   you know you can trivially modify it or download it to your own instance.
+
+## Future Goals / Endgame
+1. Mobile apps.  This can run on your old phone.  Maybe you won't be hosting
+   the web interface publicly, but you can sync, install and edit apps, and
+   otherwise get the full experience from a tiny touch screen.
+
+2. The universal application runtime.  The web browser is the universal
+   platform, but even for the simplest application that you might want to host
+   for your friends, cloud hosting, containers, and complicated dependencies might
+   all enter the mix.  Tilde Friends, though it is yet another thing to host,
+   includes everything you need out of the box to run a vast variety of interesting
+   apps.
+
+   Tilde Friends will be built out, gradually providing safe access to host
+   resources and client resources the same way web browsers extended access to
+   resources like GPU, persistent storage, cameras, ... over the years.
+
+   Not much effort has been put forward yet to having a robust, long-lasting API,
+   but since the client side longevity is already handled by web browsers, it
+   seems possible that the server-side API can be managed in a similar way.
+
+3. An awesome development environment.  Right now it runs JavaScript from the
+   first embeddable text editor I could poorly configure enough to edit code,
+   but it could incorporate a debugger, source control integration a la ssb-git,
+   merge tools, and transpiling from all sorts of different languages.
