 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 1.8.9, rebuilt for 1.12.2. 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).
+The easiest way to install Baritone is to install [Impact](https://impactdevelopment.github.io/), which comes with Baritone. The second easiest way (for 1.12.2 only) is to install the v1.2.* forge api jar from [releases](https://github.com/cabaletta/baritone/releases). Otherwise, see [Installation & setup](SETUP.md). Once Baritone is installed, look [here](USAGE.md) for instructions on how to use it.

 ## Prebuilt official releases
 These releases are not always completely up to date with latest features, and are only released from `master`. (so if you want `backfill-2` branch for example, you'll have to build it yourself)
 
 Link to the releases page: [Releases](https://github.com/cabaletta/baritone/releases)
 
+v1.2.* is for 1.12.2, v1.3.* is for 1.13.2
+
 Any official release will be GPG signed by leijurv (44A3EA646EADAC6A) and ZeroMemes (73A788379A197567). Please verify that the hash of the file you download is in `checksums.txt` and that `checksums_signed.asc` is a valid signature by those two public keys of `checksums.txt`. 
 
 The build is fully deterministic and reproducible, and you can verify Travis did it properly by running `docker build --no-cache -t cabaletta/baritone .` 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).

 # Prefix
 
-Baritone commands can by default be typed in the chatbox. However if you make a typo, like typing "gola 10000 10000" instead of goal it goes into public chat, which is bad.
-
-Therefore you can use a prefix before your messages.
-
-On Baritone v1.1.0 and newer: The prefix is `#` by default. Anything beginning with `#` isn't sent, and is only interpreted by Baritone.
-For older than v1.1.0, `#` must be enabled by toggling on the `prefix` setting.
-
-**Only** in Impact is `.b` also a valid prefix. In 4.4, `#` does **not** work, neither does saying the commands directly in chat. `#` works by default in 4.5 (not 4.4).
-
-Other clients like Kami and Asuna have their own custom things (like `-path`), and can disable direct chat control entirely.
+Baritone's chat control prefix is `#` by default. In Impact, you can also use `.b` as a prefix. (for example, `.b click` instead of `#click`)
 
+Baritone commands can also by default be typed in the chatbox. However if you make a typo, like typing "gola 10000 10000" instead of "goal" it goes into public chat, which is bad, so using `#` is suggested.
 
+To disable direct chat control (with no prefix), turn off the `chatControl` setting. To disable chat control with the `#` prefix, turn off the `prefixControl` setting. In Impact, `.b` cannot be disabled. Be careful that you don't leave yourself with all control methods disabled (if you do, reset your settings by deleting the file `minecraft/baritone/settings.txt` and relaunching).
 
 # Commands
 
 **All** of these commands may need a prefix before them, as above ^.
 
-`help` for (rudimentary) help. You can see what it says [here](https://github.com/cabaletta/baritone/blob/master/src/main/java/baritone/utils/ExampleBaritoneControl.java#L53).
+`help` for (rudimentary) help. You can see what it says [here](https://github.com/cabaletta/baritone/blob/master/src/api/java/baritone/api/utils/ExampleBaritoneControl.java#L47).
 
 To toggle a boolean setting, just say its name in chat (for example saying `allowBreak` toggles whether Baritone will consider breaking blocks). For a numeric setting, say its name then the new value (like `primaryTimeoutMS 250`). It's case insensitive. To reset a setting to its default value, say `acceptableThrowawayItems reset`. To reset all settings, say `reset`. To see all settings that have been modified from their default values, say `modified`.

 Some common examples:
 - `thisway 1000` then `path` to go in the direction you're facing for a thousand blocks
-- `goal x y z` or `goal x z` or `goal y`, then `path` to go to a certain coordinate
+- `goal x y z` or `goal x z` or `goal y`, then `path` to set a goal to a certain coordinate then path to it
+- `goto x y z` or `goto x z` or `goto y` to go to a certain coordinate (in a single step, starts going immediately)
 - `goal` to set the goal to your player's feet
 - `goal clear` to clear the goal
 - `cancel` or `stop` to stop everything
 - `goto portal` or `goto ender_chest` or `goto block_type` to go to a block. (in Impact, `.goto` is an alias for `.b goto` for the most part)
 - `mine diamond_ore` to mine diamond ore (turn on the setting `legitMine` to only mine ores that it can actually see. It will explore randomly around y=11 until it finds them.)
 - `click` to click your destination on the screen. Right click path to on top of the block, left click to path into it (either at foot level or eye level), and left click and drag to clear all blocks from an area.
-- `follow playerName` to follow a player. `follow` to follow the entity you're looking at (only works if it hitting range). `followplayers` to follow any players in range (combine with Kill Aura for a fun time).
+- `follow playerName` to follow a player. `followplayers` to follow any players in range (combine with Kill Aura for a fun time). `followentities` to follow any entities. `followentity pig` to follow entities of a specific type.
 - `save waypointName` to save a waypoint. `goto waypointName` to go to it.
 - `build` to build a schematic. `build blah` will load `schematics/blah.schematic` and build it with the origin being your player feet. `build blah x y z` to set the origin. Any of those can be relative to your player (`~ 69 ~-420` would build at x=player x, y=69, z=player z-420).
+- `schematica` to build the schematic that is currently open in schematica
 - `tunnel` to dig just straight ahead and make a tunnel
 - `farm` to automatically harvest, replant, or bone meal crops
 - `axis` to go to an axis or diagonal axis at y=120 (`axisHeight` is a configurable setting, defaults to 120).
