+# Warning: Old Branch!!
+
+**Click [here](https://github.com/cabaletta/baritone) to go to the current Baritone readme.**
+
+**This branch (`master`) is Baritone for Minecraft 1.12.2. This is the original version of Minecraft that Baritone was written for, and it was the primary development branch for over 5 years. As such, it's quite mature, and arguably more reliable than Baritone for newer versions of Minecraft. Nevertheless, as of August 2023, with [2b2t's update from 1.12.2 to 1.19.4](https://2b2t.org/update/), I decided to move Baritone's primary development branch accordingly. PRs should now be made against the `1.19.4` branch going forward. This branch might see some fixes going forward, particularly to newer features such as `#elytra`, but it won't be the primary focus anymore.**
+
+The other intermediary branches (`1.13.2`, `1.14.4`, `1.15.2`, `1.16.5`, `1.17.1`, `1.18.2`, `1.19.2`, and `1.19.3`) will probably not receive any updates at all. You can find their last releases in the releases tab, or in the quick download links table.
+
+For `1.16.5` and `1.18.2`, the latest release is fully up to date with the code. ZacSharp merged master into some of those versions even after they were deprecated, if you are for some reason really interested in the latest Baritone bugfixes on these versions of Minecraft, you can build from source as of these commits: [1.13.2](https://github.com/cabaletta/baritone/commit/be54b8ee5b5639f80e3d6809ed1abd52444d8a08), [1.14.4](https://github.com/cabaletta/baritone/commit/be54b8ee5b5639f80e3d6809ed1abd52444d8a08), [1.15.2](https://github.com/cabaletta/baritone/commit/45abbb7fa1062cefc26abbb006a02a4edd6faa32), [1.17.1](https://github.com/cabaletta/baritone/commit/cbf0d79c9c5f7454071dc0a5289261ec9ca4373f), [1.19.2](https://github.com/cabaletta/baritone/commit/217dca53633610edc9483fda7a234e46c839fd99). For `1.19.3`, merging [this](https://github.com/cabaletta/baritone/commit/217dca53633610edc9483fda7a234e46c839fd99) commit into it is trivial and is left as an exercise for the reader. For other versions in between these (for example people always ask in the Discord for 1.16.1), you'll have to figure it out yourself.

-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/v1.2.17/baritone-api-forge-1.2.17.jar)**. Otherwise, see [Installation & setup](SETUP.md). Once Baritone is installed, look [here](USAGE.md) for instructions on how to use it.
+**Message for 2b2t players looking for 1.19/1.20 Baritone** Download it from right above ^. But also please check back in a few days for Baritone Elytra ([vid 1](https://youtu.be/4bGGPo8yiHo) [vid 2](https://www.youtube.com/watch?v=pUN9nmINe3I)), which will be ported to 1.19/1.20 soon! It will work on 2b2t with its anticheat, that was the whole point of Baritone Elytra (it's fully vanilla compatible). Also join [**the discord**](http://discord.gg/s6fRBAUpmr). Thanks!
 
-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)**.
+**How to immediately get started:** Type `#goto 1000 500` in chat to go to x=1000 z=500. Type `#mine diamond_ore` to mine diamond ore. Type `#stop` to stop. For more, read [the usage page](USAGE.md) and/or watch this [tutorial playlist](https://www.youtube.com/playlist?list=PLnwnJ1qsS7CoQl9Si-RTluuzCo_4Oulpa). Also try `#elytra` for Elytra flying in the Nether using fireworks.
 
-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)**.
+For other versions of Minecraft or more complicated situations or for development, see [Installation & setup](SETUP.md). Also consider just installing [Impact](https://impactclient.net/), which comes with Baritone and is easier to install than wrangling with version JSONs and zips. For 1.16.5, [click here](https://www.youtube.com/watch?v=_4eVJ9Qz2J8) and see description. Once Baritone is installed, look [here](USAGE.md) for instructions on how to use it. There's a [showcase video](https://youtu.be/CZkLXWo4Fg4) made by @Adovin#6313 on Baritone which I recommend.
 
 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).
