+# Integration between Baritone and Impact
+
+Baritone will be in Impact 4.4 with nice integrations with its hacks, but if you're impatient you can run Baritone on top of Impact 4.3 right now.
+
+First, clone and setup Baritone (instructions in main README.md).
+
+Then, build the jar. From the command line, it's `./gradlew build` (or `gradlew build` on Windows). In IntelliJ, you can just start the `build` task in the Gradle menu.
+
+Then, copy it into place. It should be `build/libs/baritone-1.0.0.jar` in baritone. Copy it to your libraries in your Minecraft install. For example, on Mac I do `cp Documents/baritone/build/libs/baritone-1.0.0.jar Library/Application\ Support/minecraft/libraries/cabaletta/baritone/1.0/baritone-1.0.jar`. The first time you'll need to make the directory `cabaletta/baritone/1.0` in libraries first.
+
+Then, we'll need to modify the Impact launch json. Open `minecraft/versions/1.12.2-Impact_4.3/1.12.2-Impact_4.3.json`.
+
+- Add the Baritone tweak class to line 7 "minecraftArguments" like so: `"minecraftArguments": " ... --tweakClass clientapi.load.ClientTweaker --tweakClass baritone.launch.BaritoneTweakerOptifine",`. You need the Optifine tweaker even though there is no Optifine involved, for reasons I don't quite understand.
+- Add the Baritone library. Insert `{ "name": "cabaletta:baritone:1.0" },` between Impact and ClientAPI, which should be between lines 15 and 16.
+
+Restart the Minecraft launcher, then load Impact 4.3 as normal, and it should now include Baritone.
