 - **Block breaking** Baritone considers breaking blocks as part of its path. It also takes into account your current tool set and hot bar. For example, if you have a Eff V diamond pick, it may choose to mine through a stone barrier, while if you only had a wood pick it might be faster to climb over it.
 - **Block placing** Baritone considers placing blocks as part of its path. This includes sneak-back-placing, pillaring, etc. It has a configurable penalty of placing a block (set to 1 second by default), to conserve its resources. The list of acceptable throwaway blocks is also configurable, and is cobble, dirt, or netherrack by default. <a href="https://www.youtube.com/watch?v=F6FbI1L9UmU">Example</a>
 - **Falling** Baritone will fall up to 3 blocks onto solid ground (configurable, if you have Feather Falling and/or don't mind taking a little damage). If you have a water bucket on your hotbar, it will fall up to 23 blocks and place the bucket beneath it. It will fall an unlimited distance into existing still water.
-- **Vines and ladders** Baritone understands how to climb and descend vines and ladders. There is experimental support for more advanced maneuvers, like strafing to a different ladder / vine column in midair (off by default, setting named `allowVines`).
+- **Vines and ladders** Baritone understands how to climb and descend vines and ladders. There is experimental support for more advanced maneuvers, like strafing to a different ladder / vine column in midair (off by default, setting named `allowVines`). Baritone can break its fall by grabbing ladders / vines midair, and understands when that is and isn't possible.
 - **Opening fence gates and doors**
 - **Slabs and stairs**
 - **Falling blocks** Baritone understands the costs of breaking blocks with falling blocks on top, and includes all of their break costs. Additionally, since it avoids breaking any blocks touching a liquid, it won't break the bottom of a gravel stack below a lava lake (anymore).

-# Integration between Baritone and Impact
-Impact 4.4 has Baritone included.
-
-These instructions apply to Impact 4.3.
-
-For Forge follow the instructions in [Setup](SETUP.md).
-
-To run Baritone on Vanilla, just follow the instructions in the README (it's `./gradlew runClient`).
-
-## An Introduction
-There are some basic steps to getting Baritone setup with Impact.
-- Acquiring a build of Baritone
-- Placing Baritone in the libraries directory
-- Modifying the Impact Profile JSON to run baritone
-- How to use Baritone
-
-## Acquiring a build of Baritone
-There are two methods of acquiring a build of Baritone
-
-### Official Release (Not always up to date)
-https://github.com/cabaletta/baritone/releases
-
-For Impact 4.3, there is no Baritone integration yet, so you will want `baritone-standalone-X.Y.Z.jar`. **For the rest of this guide, replace `X.Y.Z` with the actual numeric version you are using.**
-
-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).
-
-### Building Baritone yourself
-You can either build Baritone through a command line or through IntelliJ's UI, information on that can be found [here](SETUP.md#building).
-
-## Placing Baritone in the libraries directory
-``/libraries`` is a neat directory in your <a href="https://minecraft.gamepedia.com/.minecraft">Minecraft Installation Directory</a>
-that contains all of the dependencies that are required from the game and some mods. This is where we will be
-putting baritone.
-- Locate the ``libraries`` folder, it should be in the Minecraft Installation Directory
-- Create 3 new subdirectories starting from ``libraries``
-  - ``cabaletta``
-    - ``baritone``
-      - ``X.Y.Z``
- - Copy the build of Baritone that was acquired earlier, and place it into the ``X.Y.Z`` folder, renamed like so:
-   - The full path should look like ``<Minecraft>/libraries/cabaletta/baritone/X.Y.Z/baritone-X.Y.Z.jar``
-
-## Modifying the Impact Profile JSON to run baritone
-The final step is "registering" the Baritone library with Impact, so that it loads on launch.
-- Ensure your Minecraft launcher is closed
-- Navigate back to the Minecraft Installation Directory
-- Find the ``versions`` directory, and open in
-- In here there should be a ``1.12.2-Impact_4.3`` folder.
-  - If you don't have any Impact folder or have a version older than 4.3, you can download Impact <a href="https://impactdevelopment.github.io">here</a>.
-- Open the folder and inside there should be a file called ``1.12.2-Impact_4.3.json``
-- Open the JSON file with a text editor that supports your system's line endings
-  - For example, Notepad on Windows likely will NOT work for this. You should instead use a Text Editor like
-  <a href="https://notepad-plus-plus.org/">Notepad++</a> if you're on Windows. (For other systems, I'm not sure
-  what would work the best so you may have to do some research.)
-- Find the ``libraries`` array in the JSON. It should look something like this.
-    ```
-    "libraries": [
-        {
-            "name": "net.minecraft:launchwrapper:1.12"
-        },
-        {
-            "name": "com.github.ImpactDevelopment:Impact:4.3-1.12.2",
-            "url": "https://impactdevelopment.github.io/maven/"
-        },
-        {
-            "name": "com.github.ImpactDeveloment:ClientAPI:3.0.2",
-            "url": "https://impactdevelopment.github.io/maven/"
-        },
-        ...
-    ```
-- Create two new objects in the array, between the ``Impact`` and ``ClientAPI`` dependencies preferably.
-    ```
-    {
-        "name": "cabaletta:baritone:X.Y.Z"
-    },
-    {
-        "name": "com.github.ImpactDevelopment:SimpleTweaker:1.2",
-        "url": "https://impactdevelopment.github.io/maven/"
-    },
-    ```
-- Now find the ``"minecraftArguments": "..."`` text near the top.
-- At the very end of the quotes where it says ``--tweakClass clientapi.load.ClientTweaker"``, add on the following so it looks like:
-  - ``--tweakClass clientapi.load.ClientTweaker --tweakClass baritone.launch.BaritoneTweaker"``
-- If you didn't close your launcher for this step, restart it now.
-- You can now launch Impact 4.3 as normal, and Baritone should start up

 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 [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 forge 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.

 ## More Info
-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"`). 
+To replace out Impact 4.5's Baritone build with a customized one, build Baritone as above then copy & **rename** `dist/baritone-api-$VERSION$.jar` into `minecraft/libraries/cabaletta/baritone-api/1.2/baritone-api-1.2.jar`, replacing the jar that was previously there. You also need to edit `minecraft/versions/1.12.2-Impact_4.5/1.12.2-Impact_4.5.json`, find the line `"name": "cabaletta:baritone-api:1.2"`, remove the comma from the end, and **entirely remove the NEXT line** (starts with `"url"`). **Restart your launcher** then load as normal. 
 
-Impact 4.4 **only** works with builds from the quite outdated `impact4.4-compat` branch. If you must have the latest Baritone features with Impact, and can't wait for 4.5, consider creating a standalone (non forge) build then adding it to Impact 4.**3** via the instructions in [Install](INSTALL.md).
+You can verify whether or not it worked by running `.b version` in chat (only valid in Impact). It should print out the version that you downloaded. Note: The version that comes with 4.5 is `v1.2.3`.

 # 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 4.4 is `.b` also a valid prefix. In 4.4, `#` does **not** work, neither does saying the commands directly in chat.
-
-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).

 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
@@ -34,14 +24,20 @@ Some common examples:
 - `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).
 - `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).
+- `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).
+- `explore x z` to explore the world from the origin of x,z. Leave out x and z to default to player feet. This will continually path towards the closest chunk to the origin that it's never seen before. `explorefilter filter.json` with optional invert can be used to load in a list of chunks to load.
 - `invert` to invert the current goal and path. This gets as far away from it as possible, instead of as close as possible. For example, do `goal` then `invert` to run as far as possible from where you're standing at the start.
-- `render` to rerender the world in case `renderCachedChunks` is being glitchy
+- `version` to get the version of Baritone you're running
 - `damn` daniel

 # Troubleshooting / common issues
 
-## Baritone highlights a block in green but gets completely stuck? Also I'm using Baritone with Future?
-Baritone is trying to right click to place a block there, but it can't since there's a conflicting mixin. Baritone can't force click right click when Future is also installed. Left click **does work** on recent Baritone even with Future, however. For now, turn off `allowPlace` and Baritone will only search for paths that don't require placing blocks to complete. `allowBreak` can remain on.
-
 ## Why doesn't Baritone respond to any of my chat commands?
 This could be one of many things.
