Build 1.21.6 with Stonecutter from the shared src/

1.21.6's copy only differed from 1.21.7's in RenderScopeImpl: item
rendering uses ItemRenderState, which 1.21.7 renamed to
KeyedItemRenderState. That's behind a version comment; 1.21.6 keeps its
older loader_version (0.18.5) in its gradle.properties.

Moving a version over leaves the old mc-<v> project's compiled classes in
the shared build/ folder, so a removed class (1.21.6's dead NameTagMixin)
still got packaged until a clean. VERSION_GUIDE now says to run
:<v>:clean once after moving a version.

-## ✨ About
+## About
 
 Saturn Client is a free, open-source Minecraft client designed to enhance the gameplay experience while staying lightweight and customizable.
 Our goal is to build a clean, optimized client that the community can contribute to and improve together.
 
-Saturn is currently trying to support multiple versions of minecraft, so please report any issues you are experiencing.
+Saturn runs on Fabric and supports **Minecraft 1.21.4 to 1.21.11**, with one build per version. If something doesn't work on your version, please open an issue.

-- Free cosmetics that don't require real money
+- Free cosmetics that don't require real money: cloaks, including animated ones, and hats
+- 18 built-in mods: Armor Display, Auto Sprint, Clock, Coordinates, Crosshair, Day Counter, FPS Display, Freelook, Fullbright, Health Display, Keystrokes, Nametags, No Fog, Ping Display, Speedometer, Status Effects, TPS Display and Zoom
 - Clean and modern UI with animations
 - Ongoing performance improvements
 - Open-source and community-driven
 
----
+## Installation
 
-## 🤝 Contributing
+1. Install [Fabric Loader](https://fabricmc.net/use/) and [Fabric API](https://modrinth.com/mod/fabric-api) for your Minecraft version.
+2. Download the Saturn Client jar for the same version from [Modrinth](https://modrinth.com/mod/saturnclient) or the [releases page](https://git.selimaj.dev/saturnclientmc/saturnclient/releases).
+3. Put it in your `mods` folder.
+
+### Network use
+
+For cosmetics, Saturn Client connects to the Saturn server (`saturn-server.selimaj.dev`). You're signed in the same way as on an online-mode Minecraft server: your client proves who you are to Mojang's session server, and the Saturn server asks Mojang to confirm it. **Your Minecraft access token is only ever sent to Mojang, never to the Saturn server.**
+
+## Building from source
+
+The version-independent code lives in the `common` submodule, so clone with submodules:
+
+```sh
+git clone --recurse-submodules https://git.selimaj.dev/saturnclientmc/saturnclient.git
+cd saturnclient
+
+./gradlew buildAll                    # every version → build/allJars/
+./gradlew :1.21.11:build              # a single version (versions not on Stonecutter yet: :mc-1.21.5)
+./gradlew :1.21.11:runClient          # launch a development client
+```
+
+Building needs Java 21.

 # Version guide
 
-This guide will help you to add or edit minecraft versions.
+How Saturn Client supports several Minecraft versions, and how to change or add one.
+
+## Layout
+
+Saturn is moving from one full copy of the version-specific code per Minecraft version to a single copy built with [Stonecutter](https://stonecutter.kikugie.dev/) (issue #8). During the move there are two kinds of version:
+
+- `common/`: all version-independent code (mods, UI, cosmetics, the server client). It has no Minecraft dependency and reaches the game only through the interfaces in `org.saturnclient.common`.
+- `src/`: the version-specific code (providers, refs, mixins and the three mixin configs) for the versions built by Stonecutter, currently **1.21.6 to 1.21.11**. It's one copy: where Minecraft's API differs between them, the code goes behind version comments (see below). Each of these versions is the Gradle project `:<mc>`, and `versions/<mc>/` holds only its `gradle.properties` (Minecraft, Yarn, Fabric Loader and Fabric API versions), `build/` and `run/`.
+- `versions/<mc>/src/`: the versions not moved yet (1.21.4 and 1.21.5), each a full copy, as the Gradle project `:mc-<mc>` with its own `build.gradle`.
+
+`settings.gradle.kts` lists the Stonecutter versions in `stonecutterVersions` and includes every other folder under `versions/` as `:mc-<mc>`. The root `build.gradle.kts` builds each Stonecutter version, and `stonecutter.gradle.kts` configures the root project (shared repositories, the `common` wiring and `buildAll`). Loom's version for the Stonecutter versions is `loom_version` in the root `gradle.properties`.
+
+## Version-specific code with Stonecutter
+
+The code in `src/` is always plain Java for the **active** version (1.21.11, set in `stonecutter.gradle.kts`). Code for other versions sits in comments that Stonecutter swaps before building each version:
+
+```java
+//? if >=1.21.9 {
+public void render(MatrixStack matrices, OrderedRenderCommandQueue queue, int light, PlayerEntityRenderState state, float limbAngle, float limbDistance) {
+//?} else
+//public void render(MatrixStack matrices, VertexConsumerProvider consumers, int light, PlayerEntityRenderState state, float limbAngle, float limbDistance) {
+```
+
+A condition without braces covers the next line only. For several lines, use braces and wrap the inactive block in `/* … */`:
+
+```java
+//? if >=1.21.11 {
+import net.minecraft.client.render.RenderLayers;
+import net.minecraft.client.render.RenderSetup;
+//?} else {
+/*import net.minecraft.client.render.RenderPhase.Textures;
+*///?}
+```
+
+Stonecutter rewrites inactive code into its own layout when switching versions (a single inactive line becomes `//code`), so write it that way to begin with, or run a switch and a reset before committing.
+
+When a newer version leaves something out that an older one implements, keep the older version's code behind a condition and mark the newer branch with a `TODO`, rather than dropping it for every version. `WorldFeatureImpl.getWorldAge` and `SaturnScreenFabric.resize` are examples. Search for `TODO` to find what newer versions still lack.
+
+A whole class that only exists for some versions (such as `NametagsMixin`, which hooks a method that 1.21.9 changed) can keep an empty class body on the other versions. An empty mixin changes nothing, and it keeps the mixin configs the same for every version, since JSON can't hold version comments.
+
+Inactive code sits inside a `/* … */` comment, so it can't contain `/* … */` comments itself: use `//` comments in code that's only active for some versions. For the same reason, don't nest multi-line version blocks; use `//?} else if <condition> {` for more than two version ranges, as in `PlayerEntityRendererMixin` and `SaturnRenderState`.
+
+- `./gradlew "Set active project to <mc>"` (or the Stonecutter IntelliJ plugin) rewrites `src/` so that version's code is the uncommented one, for editing it in the IDE.
+- `./gradlew "Reset active project"` switches back to 1.21.11. **Run it before committing**, so `src/` is always committed with 1.21.11 active.
+- Each version's processed copy is compiled from `versions/<mc>/build/generated/stonecutter/`, which is also where to look when a non-active version fails to compile.
+
+The `emotes` repository uses the same setup, and its `BentCubeRenderer` and `PlayerModelMixin` are small examples of version comments.
+
+## Porting a change to the other versions
+
+Make the change in one version, usually the newest, then run:
+
+```sh
+scripts/port.sh                        # port uncommitted changes to every other version
+scripts/port.sh --dry-run              # see what would apply cleanly first
+scripts/port.sh --to 1.21.4,1.21.5     # only some versions
+scripts/port.sh --commit <rev>         # port what a commit changed instead
+```
+
+The script applies the diff under one version's source to each other version with `git apply --3way`. The Stonecutter `src/` counts as one version (1.21.11), so changes port between it and the old copies in both directions:
+
+- **applied**: the files matched, and nothing else is needed.
+- **CONFLICTS**: that version's code really differs. The file gets normal conflict markers, with the version's own code in `ours` and the ported change in `theirs`. Adapt the change to that version's API and resolve.
+- **already has this change**: nothing to do, which is safe to see when re-running.
+
+Only source is ported. `build.gradle` and `gradle.properties` are version-specific on purpose. Then build everything:
+
+```sh
+./gradlew compileJava
+```
+
+The **Check** workflow runs the same compile on every pull request, so a version that was missed or mis-ported fails before merging.
+
+## Adding a Minecraft version
+
+Add new versions to Stonecutter rather than copying a folder:
+
+1. Create `versions/<new>/gradle.properties` with `minecraft_version`, `yarn_mappings`, `loader_version` and `fabric_api_version` (copy 1.21.11's and change the values; they're listed at <https://fabricmc.net/develop>). Loom's version is shared, in the root `gradle.properties`.
+2. Add `<new>` to `stonecutterVersions` in `settings.gradle.kts`. When moving an existing `mc-<v>` version over instead, delete its `versions/<v>/src` and run `./gradlew :<v>:clean` once: the new project shares the old one's `build/` folder, and classes compiled from the removed sources would otherwise end up in the jar.
+3. Build it with `./gradlew :<new>:compileJava` and put what Minecraft changed behind version comments. Check the mixin configs in `src/main/resources/*.mixins.json` as well: a mixin whose target changed fails at startup, not at compile time, so launch it with `./gradlew :<new>:runClient`.
+4. The release workflow builds everything through `buildAll`, and "Publish to Modrinth" takes the game version from each jar's name, so neither needs changing.
