+# 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.

-# base64c
-This is primarily just a fork of a base64 decoder from the FreeBSD codebase. It has received a few modifications:
-  * removed all allocations, you are expected to pass in a buffer that has sufficient space and you will get an error (-1) if you run out of space
-  * replaced a dynamically generated lookup table with a hardcoded lookup table
-  * wrote my own unit tests, i'm sure there are tests for freebsd somewhere but i didn't find them
-
-# Embedding
-This code is primarily intended to be dropped into an existing code base ( or perhaps using submodules). To do that:
-  
-  * grab include/base64c.h
-  * grab src/base64c.h
-
-# Usage
-
-Call base64c_encoding_length() to calculate how big a buffer you need to encode a string. It's somewhere around 4 times the size of the input string. This length includes a null terminator.
-
-```c
-char input_string[256];
-
-size_t new_len = base64c_encoding_length( strlen(input_string));
-
-unsigned char *buffer = (unsigned char*)malloc(new_len);
-```
-
-Call base64c_encode() to actually encode your input string as base64. It will write to the buffer and return how many characters were written. If there was an error it will return -1.
-
-```c
-size_t output_length = base64c_encode(input_string, strlen(input_string), buffer, new_len);
-
-if (output_length == -1) {
-  int x = 1/0; // ERROR!
-}
-```
-
-Call base64c_decoding_length() to calculate how big a buffer you need to decode. It comes out to about half the size. This number isn't always exact, but it is close to within a byte or two.
-
-```c
-size_t decode_len = base64c_decoding_length( strlen(buffer) );
-
-unsigned char *decoded = (unsigned char*)malloc( decode_len );
-```
-
-Call base64c_decode() to decode an encoded base64 string. It will write to the buffer and return how many characters were written. IF there was an error it will return -1. If the string contains invalid number of characters, or has any characters that are not part of the base64 character set an error will be returned.
-
-# Building
-
-You need to bootstrap all the autoconf tools by running ./autogen.sh
-
-You need to have autoconf installed to do this.
-
-Once bootstrapped run ./configure
-
-# Tests
-
-There are tests in the test/ subfolder. They will be built automatically. There is no special test runner. You can run each of the test cases manually to check whether the code is working properly.
