 ### Documentation
 When writing documentation for [CC: Tweaked's documentation website][docs], it may be useful to build the documentation
 and preview it yourself before submitting a PR.
 
-Building all documentation is, sadly, a multi-stage process (though this is largely hidden by Gradle). First we need to
-convert Java doc-comments into Lua ones, we also generate some Javascript to embed. All of this is then finally fed into
-illuaminate, which spits out our HTML.
+Our documentation generation pipeline is rather complex, and involves invoking several external tools. Most of this
+complexity is hidden by Gradle, but you will need to perform some initial setup:
 
-#### Setting up the tooling
-For various reasons, getting the environment set up to build documentation can be pretty complex. I'd quite like to
-automate this via Docker and/or nix in the future, but this needs to be done manually for now.
+ - Install [Node/npm][node].
+ - Run `npm ci` to install our Node dependencies.
 
-This tooling is only needed if you need to build the whole website. If you just want to generate the Lua stubs, you can
-skp this section.
- - Install Node/npm and install our Node packages with `npm ci`.
- - Install [illuaminate][illuaminate-usage] as described above.
-
-#### Building documentation
-Gradle should be your entrypoint to building most documentation. There's two tasks which are of interest:
-
- - `./gradlew luaJavadoc` - Generate documentation stubs for Java methods.
- - `./gradlew docWebsite` - Generate the whole website (including Javascript pages). The resulting HTML is stored at
-   `./build/docs/site/`.
+You can now run `./gradlew docWebsite`. This generates documentation from our Lua and Java code, writing the resulting
+HTML into `./build/docs/site`.
 
 #### Writing documentation
 illuaminate's documentation system is not currently documented (somewhat ironic), but is _largely_ the same as
 [ldoc][ldoc]. Documentation comments are written in Markdown,
 
 Our markdown engine does _not_ support GitHub flavoured markdown, and so does not support all the features one might
-expect (such as tables). It is very much recommended that you build and preview the docs locally first.
+expect. It is recommended that you build and preview the docs locally first.
+
+When iterating on documentation, you can get Gradle to rebuild the website every time a file changes by running
+`./gradlew docWebsite -t`. This will take a couple of seconds to run, but definitely beats running it manually!

 The speaker program plays audio files using speakers attached to this computer.
 
+It supports audio files in a limited number of formats:
+* DFPWM: You can convert music to DFPWM with external tools like https://music.madefor.cc.
+* WAV: WAV files must be 8-bit PCM or DFPWM, with exactly one channel and a sample rate of 48kHz.

 ## Examples:
-- `speaker play example.dfpwm left` plays the "example.dfpwm" audio file using the speaker on the left of the computer.
-- `speaker stop` stops any currently playing audio.
