 the original version of the bot for Minecraft 1.8, rebuilt for 1.12.2. Baritone focuses on reliability and particularly performance (it's over [29x faster](https://github.com/cabaletta/baritone/pull/180#issuecomment-423822928) than MineBot at calculating paths).

 # Setup
 
-## IntelliJ's Gradle UI
-- Open the project in IntelliJ as a Gradle project
-- Run the Gradle task `setupDecompWorkspace`
-- Run the Gradle task `genIntellijRuns`
-- Refresh the Gradle project (or just restart IntelliJ)
-- Select the "Minecraft Client" launch config and run
-
 ## Command Line
 On Mac OSX and Linux, use `./gradlew` instead of `gradlew`.
 
 Running Baritone:
 
 ```
-$ gradlew run
+$ gradlew runClient
 ```
 
-Setting up for IntelliJ:
+Building Baritone:
 ```
-$ gradlew setupDecompWorkspace
-$ gradlew --refresh-dependencies
-$ gradlew genIntellijRuns
+$ gradlew build
 ```
 
+For example, to replace out Impact 4.4's Baritone build with a customized one, build Baritone as above then copy `dist/baritone-api-$VERSION.jar` into `minecraft/libraries/cabaletta/baritone-api/1.0.0/baritone-api-1.0.0.jar`, replacing the jar that was previously there. You also need to edit `minecraft/versions/1.12.2-Impact_4.4/1.12.2-Impact_4.4.json`, find the line `"name": "cabaletta:baritone-api:1.0.0"`, remove the comma from the end, and entirely remove the line that's immediately after (starts with `"url"`). 
+
+## IntelliJ's Gradle UI
+- Open the project in IntelliJ as a Gradle project
+- Run the Gradle task `setupDecompWorkspace`
+- Run the Gradle task `genIntellijRuns`
+- Refresh the Gradle project (or, to be safe, just restart IntelliJ)
+- Select the "Minecraft Client" launch config
+- In `Edit Configurations...` you may need to select `baritone_launch` for `Use classpath of module:`.
