+ *
+ * {@snippet class=com.example.examplemod.ExampleMod region=turtle_upgrades}

+ * Minecraft objects. The approach to do this will depend on mod-loader.

+ * <h4>Forge</h4>
+ * {@snippet class=com.example.examplemod.ForgeExampleMod region=turtle_upgrades}
+ *
+ * <h3>Rendering the upgrade</h3>
+ * Next, we need to register a model for our upgrade. This is done by registering a

+ *
+ * {@snippet file = data/examplemod/computercraft/turtle_upgrades/example_turtle_upgrade.json}

+<p>
+    This is the documentation for CC: Tweaked $modVersion for Minecraft $mcVersion. Documentation for other versions of
+    Minecraft are available on the CC: Tweaked website:
+
+<ul>
+    <li><a href="/mc-1.20.x/javadoc/">Minecraft 1.20.1</a>
+    <li><a href="/mc-1.21.x/javadoc/">Minecraft 1.21.1</a>

+
+<h1>Quick links</h1>
+<p>
+    You probably want to start in the following places:
+
+<ul>
+    <li>{@linkplain dan200.computercraft.api.peripheral Registering new peripherals}</li>
+    <li>
+        {@link dan200.computercraft.api.lua.LuaFunction} and {@link dan200.computercraft.api.lua.IArguments} for
+        adding methods to your peripheral or Lua objects.

+    <li>{@linkplain dan200.computercraft.api.turtle.ITurtleUpgrade Turtle upgrades}</li>
+    <li>{@linkplain dan200.computercraft.api.pocket.IPocketUpgrade Pocket upgrades}</li>
+</ul>
+
+<h1>Using</h1>
+<p>
+    CC: Tweaked is hosted on my maven repo, and so is relatively simple to depend on. You may wish to add a soft (or
+    hard) dependency in your <code>mods.toml</code> file, with the appropriate version bounds, to ensure that API
+    functionality you depend on is present.
+
+<pre class="language language-groovy"><code>repositories {
+    maven {
+        url "https://maven.squiddev.cc"
+        content { includeGroup("cc.tweaked") }
+    }
+}
+
+dependencies {
+    // Vanilla (i.e. for multi-loader systems)
+    compileOnly("cc.tweaked:cc-tweaked-$mcVersion-common-api:$modVersion")
+
+    // Forge Gradle
+    compileOnly("cc.tweaked:cc-tweaked-$mcVersion-core-api:$modVersion")
+    compileOnly(fg.deobf("cc.tweaked:cc-tweaked-$mcVersion-forge-api:$modVersion"))
+    runtimeOnly(fg.deobf("cc.tweaked:cc-tweaked-$mcVersion-forge:$modVersion"))
+
+    // Fabric Loom
+    modCompileOnly("cc.tweaked:cc-tweaked-$mcVersion-fabric-api:$modVersion")
+    modRuntimeOnly("cc.tweaked:cc-tweaked-$mcVersion-fabric:$modVersion")
+}
+</code></pre>
+
+<p>
+    You should also be careful to only use classes within the <code>dan200.computercraft.api</code> package. Non-API
+    classes are subject to change at any point. If you depend on functionality outside the API (or need to mixin to
+    CC:T), please <a href="https://github.com/cc-tweaked/CC-Tweaked/discussions/new/choose">start a discussion</a> to
+    let me know!
