 # Wipforth
 
-Wipforth is a Forth implementation that runs in the WebAssembly
-virtual machine.  The system is bootstrapped from source on page load:
-the only non-text file is the favicon :)
+## Building and Running
 
-I/O is done via memory-mapped peripherals, which are emulated in
-JavaScript.
-
-- For the Forth kernel, see [wipforth.ws](./wipforth.ws)
-- For the emulator, see [emu.js](./emu.js)
-- For the assembler, see [asm.js](./asm.js)
-- For the prelude (Forth code loaded right after the kernel boots),
-  see [prelude.f](./prelude.f)
-- For a description of the peripherals, see the
-  [Peripherals](#peripherals) section below.
-
-## Building and Running Locally
-
-There's a [Guile](https://www.gnu.org/software/guile/) script in the
-repo you can use for this:
+To run, first compile the WebAssembly module:
 
 ```
-guile server.scm
+wat2wasm --enable-threads wipforth.wat
+```
+
+Then run the server:
+
+```
+python3 server.py
 ```
 
 You should then be able to open <http://localhost:8080> in a browser
 and use the system from there.
 
-However, since everything is bootstrapped on the client, basically any
-HTTP server will do as long as it sets the appropriate response
-headers for `SharedArrayBuffer` use:
-
-- `Cross-Origin-Opener-Policy: same-origin`
-- `Cross-Origin-Embedder-Policy: require-corp`
-
-So, if you don't have Guile on your system you can use something else
-like Python's `http.server`.
-
-**NOTE**: You should **definitely not** use `server.scm` to serve the
-application on the open internet or anything like that; I just hacked
-it together for testing on localhost during development and it's
-probably hilariously insecure.
-
-## End-to-End Tests
-
-There's a (fairly minimal at the moment) end-to-end test suite defined
-in [tests.scm](./tests.scm).  To run it you'll need:
-
-- [Guile](https://www.gnu.org/software/guile/) again (no substitute
-  this time, sorry)
-- [guile-json](https://github.com/aconchillo/guile-json)
-- Firefox
-
-I'm also pretty sure it won't work on a non-POSIX system, though I
-haven't tried it.
-
-Given that's all sorted, you should be able to run:
-
-```
-guile tests.scm
-```
-
-It will print a JUnit XML report to standard out.  You can
-pretty-print it with `xmllint` if you have it installed:
-
-```
-guile tests.scm | xmllint --format -
-```
+**NOTE**: The server is just a very simple instantiation of Python's
+built-in `http.server.HTTPServer`, configured to set the cross-origin
+headers required for `SharedMemoryBuffer` use.  You could use any HTTP
+server that sets these headers.

 For both sending (`TX`) and receiving (`RX`), there are three
 registers: `xBUF`, `xHEAD` and `xTAIL`:
 
-- `xBUF` registers are 128-byte FIFO ring buffers used for data
+- `xBUF` registers are 32-byte FIFO ring buffers used for data
 - The `xHEAD` and `xTAIL` registers specify the start and end of data
   in the ring buffer, `xHEAD` being the offset of the first byte of
-  data, and `xTAIL` being the offset of the first byte *after* the
-  data.
+  data, and `xTAIL` being the offset of the first byte *after* the data.
 
 In order to be distinguishable from the empty state, the ring buffers
 must never be completely full -- there must always be *at least one*
 unoccupied byte between the tail and the head.
