 ## ModFusioner
 
-// TODO
+ModFusioner is a gradle plugin that allow you to merge multiple mod jars into a single jar. It's intended to be used by multi-loader projects created with Architectury, MultiLoader Template or unimined.
+
+This plugin is based on, and contains code from [Forgix](https://github.com/PacifistMC/Forgix), but with massive optimizations, additional features and bug fixes.
+
+***
+
+### Usage
+
+To use this plugin inside your project, first you have to add our maven.
+
+To does this, open up settings.gradle and add the following:
+
+```groovy
+pluginManagement {
+    repositories {
+        gradlePluginPortal()
+        maven {
+            url "https://maven.firstdarkdev.xyz/releases"
+        }
+    }
+}
+```
+
+Next, in your ROOT `build.gradle` add:
+
+![badge](https://maven.firstdarkdev.xyz/api/badge/latest/releases/com/hypherionmc/modutils/modfusioner?color=40c14a&name=modfusioner)
+
+```groovy
+plugins {
+    id "com.hypherionmc.modutils.modfusioner" version "1.0.+"
+}
+```
+
+Finally, add the following to your ROOT `build.gradle` file:
+
+```groovy
+fusioner {
+    packageGroup = project.group // Package group of the merged jar. For example com.mymod.awesome
+    mergedJarName = "MyModMerged-combo-1.20.2" // The name of the output jar
+    outputDirectory = "artifacts/fused" // Where the merged jar will be stored. Defaults to artifacts/fused
+    jarVersion = final_version // The version of the mod/jar
+
+    // Forge Project
+    forge {
+        projectName = "Forge" // The name of the project that contains the forge code
+        inputTaskName = "jar" // The name of the build task for the forge project
+        // OR
+        // inputFile = "Forge/build/libs/MyMod-1.0.jar" // Use a custom jar input
+
+        // Mixin configuration files
+        // Only required if the plugin doesn't detect it directly
+        mixin "${mod_id}.mixins.json"
+        mixin "${mod_id}-forge.mixins.json"
+
+        // Packages that need to be relocated to the specific platform
+        addRelocate "me.hypherionmc.mcdiscordformatter", "forge.me.hypherionmc.mcdiscordformatter"
+    }
+
+    // Fabric Project
+    fabric {
+        projectName = "Fabric" // The name of the project that contains the fabric code
+        inputTaskName = "remapJar" // The name of the build task for the forge project
+        // OR
+        // inputFile = "Fabric/build/libs/MyMod-Fabric-1.0.jar" // Use a custom jar input
+
+        // Packages that need to be relocated to the specific platform
+        addRelocate "me.hypherionmc.mcdiscordformatter", "fabric.me.hypherionmc.mcdiscordformatter"
+    }
+
+    // Quilt Project
+    fabric {
+        projectName = "Quilt" // The name of the project that contains the quilt code
+        inputTaskName = "remapJar" // The name of the build task for the forge project
+        // OR
+        // inputFile = "Quilt/build/libs/MyMod-Quilt-1.0.jar" // Use a custom jar input
+
+        // Packages that need to be relocated to the specific platform
+        addRelocate "me.hypherionmc.mcdiscordformatter", "fabric.me.hypherionmc.mcdiscordformatter"
+    }
+
+    // For "custom", the "projectName" is a required value.
+    custom {
+        projectName = "sponge" // This is the name of the project. This is a required field.
+        inputTaskName = "jar" // The name of the build task for the forge project
+        // OR
+        // inputFile = "sponge/build/libs/MyMod-Sponge-1.0.jar" // Use a custom jar input
+
+        additionalRelocate "org.my.lib" "sponge.org.my.lib" // This is an important one to know. This is how you can remap additional packages such as libraries and stuff.
+        additionalRelocate "org.my.lib.another" "sponge.org.my.lib.another"
+    }
+
+    // Remove duplicate libraries or packages. Useful if you have shaded libraries in your mod
+    relocateDuplicate "com.hypherionmc.sdlink.shaded"
+}
+```
+
+Most values are optional, so you can only configure what you need. You need at least 2 projects in order for this plugin to work.
