 The build is fully deterministic and reproducible, and you can verify Travis did it properly by running `docker build --no-cache -t cabaletta/baritone . && docker run --rm cabaletta/baritone cat /code/dist/checksums.txt` yourself and comparing the shasum. This works identically on Travis, Mac, and Linux (if you have docker on Windows, I'd be grateful if you could let me know if it works there too).
 
 ### Building Baritone yourself
-There are a few steps to this
-- Clone this repository
-- Setup the project as instructed in the README
-- Run the ``build`` gradle task. You can either do this using IntelliJ's gradle UI or through a
-command line
-  - Windows: ``gradlew build``
-  - Mac/Linux: ``./gradlew build``
-- The build should be exported into ``/build/libs/baritone-X.Y.Z.jar``
+You can either build Baritone through a command line or through IntelliJ's UI, information on that can be found [here](SETUP.md#building).

 A Minecraft pathfinder bot. 
 
 Baritone is the pathfinding system used in [Impact](https://impactdevelopment.github.io/) since 4.4. There's a [showcase video](https://www.youtube.com/watch?v=yI8hgW_m6dQ) made by @Adovin#3153 on Baritone's integration into Impact. [Here's](https://www.youtube.com/watch?v=StquF69-_wI) a video I made showing off what it can do.
 
 This project is an updated version of [MineBot](https://github.com/leijurv/MineBot/),
-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
-
-## Command Line
-On Mac OSX and Linux, use `./gradlew` instead of `gradlew`.
-
-Running Baritone:
-
-```
-$ gradlew runClient
-```
-
-Building Baritone:
-```
-$ gradlew build
-```
-
-For example, to replace out Impact 4.4's Baritone build with a customized one, switch to the `impact4.4-compat` branch, 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 tasks `setupDecompWorkspace` then `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:`.

+
+Building Baritone will result in 3 artifacts created in the ``dist`` directory.
+
+- **API**: Only the non-api packages are obfuscated. This should be used in environments where other mods would like to use Baritone's features.
+- **Standalone**: Everything is obfuscated. This should be used in environments where there are no other mods present that would like to use Baritone's features.
+- **Unoptimized**: Nothing is obfuscated. This shouldn't be used ever in production.
