-A Minecraft pathfinder bot.
-
-[**Baritone Discord Server**](http://discord.gg/s6fRBAUpmr)
-
-Baritone is the pathfinding system used in [Impact](https://impactclient.net/) since 4.4. There's a [showcase video](https://youtu.be/CZkLXWo4Fg4) made by @Adovin#0730 on Baritone which I recommend. [Here's](https://www.youtube.com/watch?v=StquF69-_wI) a (very old!) video I made showing off what it can do.
-
-[Tutorial playlist](https://www.youtube.com/playlist?list=PLnwnJ1qsS7CoQl9Si-RTluuzCo_4Oulpa)
-
-The easiest way to install Baritone is to install [Impact](https://impactclient.net/), which comes with Baritone. The second easiest way (for 1.12.2 only) is to install the v1.2.* `api-forge` jar from [releases](https://github.com/cabaletta/baritone/releases). **For 1.12.2 Forge, just click [here](https://github.com/cabaletta/baritone/releases/download/v1.2.15/baritone-api-forge-1.2.15.jar)**. Otherwise, see [Installation & setup](SETUP.md). Once Baritone is installed, look [here](USAGE.md) for instructions on how to use it.
-
-For 1.16.5, [click here](https://www.youtube.com/watch?v=_4eVJ9Qz2J8) and see description. If you need Forge or Fabric 1.16.5, look [here](https://github.com/cabaletta/baritone/releases/tag/v1.6.3) and get the `api-forge` or `api-fabric` jar. **For 1.16.5 Fabric, just click [here](https://github.com/cabaletta/baritone/releases/download/v1.6.3/baritone-api-fabric-1.6.3.jar)**.
-
-If you need Forge or Fabric 1.17.1, look [here](https://github.com/cabaletta/baritone/releases/tag/v1.7.2) and get the `api-forge` or `api-fabric` jar. **For 1.17.1 Fabric, just click [here](https://github.com/cabaletta/baritone/releases/download/v1.7.2/baritone-api-fabric-1.7.2.jar)**.
-
-If you need Forge or Fabric 1.18.2, look [here](https://github.com/cabaletta/baritone/releases/tag/v1.8.3) and get the `api-forge` or `api-fabric` jar. **For 1.18.2 Fabric, just click [here](https://github.com/cabaletta/baritone/releases/download/v1.8.3/baritone-api-fabric-1.8.3.jar)**. **For 1.18.2 Forge, just click [here](https://github.com/cabaletta/baritone/releases/download/v1.8.3/baritone-api-forge-1.8.3.jar)**.
-
-This project is an updated version of [MineBot](https://github.com/leijurv/MineBot/),
-the original version of the bot for Minecraft 1.8.9, rebuilt for 1.12.2 onwards. Baritone focuses on reliability and particularly performance (it's over [30x faster](https://github.com/cabaletta/baritone/pull/180#issuecomment-423822928) than MineBot at calculating paths).

-
-# API
-
-The API is heavily documented, you can find the Javadocs for the latest release [here](https://baritone.leijurv.com/).
-Please note that usage of anything located outside of the ``baritone.api`` package is not supported by the API release
-jar.
-
-Below is an example of basic usage for changing some settings, and then pathing to an X/Z goal.
-
-```java
-BaritoneAPI.getSettings().allowSprint.value = true;
-BaritoneAPI.getSettings().primaryTimeoutMS.value = 2000L;
-
-BaritoneAPI.getProvider().getPrimaryBaritone().getCustomGoalProcess().setGoalAndPath(new GoalXZ(10000, 20000));
-```
-
-# FAQ
-
-## Can I use Baritone as a library in my custom utility client?
-
-That's what it's for, sure! (As long as usage complies with the LGPL 3.0 License)
-
-## How is it so fast?
-
-Magic. (Hours of [leijurv](https://github.com/leijurv/) enduring excruciating pain)

-
-We thank them for granting Baritone an OSS license so that we can make our software the best it can be.
-
-## Why is it called Baritone?
-
-It's named for FitMC's deep sultry voice.
+This branch of Baritone is deprecated. It will no longer recieve updates. Updates to older versions of Minecraft will not be merged into this branch, even if a newer branch is not deprecated (this branch will be skipped). Bug reports that only affect deprecated branches will not be addressed.
