+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* No Anime
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* Anime
+* The use of sexualized language or imagery and unwelcome sexual attention or
+ advances
+* ~~Trolling, insulting/derogatory comments, and personal or political attacks~~
+* Public or private harassment

 - **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).
@@ -22,9 +22,9 @@ Baritone uses A*, with some modifications:
 - **Backtrack cost favoring** While calculating the next segment, Baritone favors backtracking its current segment. The cost is decreased heavily, but is still positive (this won't cause it to backtrack if it doesn't need to). This allows it to splice and jump onto the next segment as early as possible, if the next segment begins with a backtrack of the current one. <a href="https://www.youtube.com/watch?v=CGiMcb8-99Y">Example</a>
 - **Backtrack detection and pausing** While path calculation happens on a separate thread, the main game thread has access to the latest node considered, and the best path so far (those are rendered light blue and dark blue respectively). When the current best path (rendered dark blue) passes through the player's current position on the current path segment, path execution is paused (if it's safe to do so), because there's no point continuing forward if we're about to turn around and go back that same way. Note that the current best path as reported by the path calculation thread takes into account the incremental cost backoff system, so it's accurate to what the path calculation thread will actually pick once it finishes.

-# Integration between Baritone and Impact
-Impact 4.4 has Baritone included.
-
-These instructions apply to Impact 4.3 (and potentially other "hacked clients").
-
-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`.
-
-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 . && 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
-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
-   - 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.BaritoneTweakerOptifine"``
-- 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
- 
- ## How to use Baritone
- Instructions on how to use Baritone are limited, and you may have to read a little bit of code (Really nothing much
-  just plain English), you can view that <a href="https://github.com/cabaletta/baritone#chat-control">here</a>.

 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.

+# Installation
 
-## Prebuilt
-[Releases](https://github.com/cabaletta/baritone/releases)
+The easiest way to install Baritone is to install [Impact](https://impactdevelopment.github.io/), which comes with Baritone.
 
-Not always completely up to date with latest features.
+Once Baritone is installed, look [here](USAGE.md) for instructions on how to use it.
 
-The forge release (currently `baritone-forge-1.1.0.jar`) can simply be added as a Forge mod. However, it is not fully compatible with the latest version of Forge. `freeLook` was broken in Forge 14.23.4.2744. You should use Forge 14.23.4.2743 or **older** with Baritone. Newer versions of Forge "work", sort of, but Baritone's movement becomes unreliable and `freeLook` must be off.
+## 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)
+
+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).
+
+
+## Artifacts
+
+Building Baritone will result in 5 artifacts created in the ``dist`` directory. These are the same as the artifacts created in the [releases](https://github.com/cabaletta/baritone/releases).
+
+**The Forge release can simply be added as a Forge mod.**
+
+If another one of your Forge mods has a Baritone integration, you want `baritone-api-forge-VERSION.jar`. Otherwise, you want `baritone-standalone-forge-VERSION.jar`
+
+- **API**: Only the non-api packages are obfuscated. This should be used in environments where other mods would like to use Baritone's features.
+- **Forge API**: Same as API, but packaged for Forge. This should be used where another mod has a Baritone integration.
+- **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.
+- **Forge Standalone**: Same as Standalone, but packaged for Forge. This should be used when Baritone is your only Forge mod, or none of your other Forge mods integrate with Baritone.
+- **Unoptimized**: Nothing is obfuscated. This shouldn't be used ever in production.
+
+## More Info
+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. 
+
+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`.

-## 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"`).

+(assuming you already have Baritone [set up](SETUP.md))
+
+# Prefix
+
+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/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` 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).
+- `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.
+- `version` to get the version of Baritone you're running
+- `damn` daniel
+
+
+For the rest of the commands, you can take a look at the code [here](https://github.com/cabaletta/baritone/blob/master/src/api/java/baritone/api/utils/ExampleBaritoneControl.java).
+
+All the settings and documentation are <a href="https://github.com/cabaletta/baritone/blob/master/src/api/java/baritone/api/Settings.java">here</a>. If you find HTML easier to read than Javadoc, you can look <a href="https://baritone.leijurv.com/baritone/api/Settings.html#field.detail">here</a>.
+
+There are about a hundred settings, but here are some fun / interesting / important ones that you might want to look at changing in normal usage of Baritone. The documentation for each can be found at the above links.
+- `allowBreak`
+- `allowSprint`
+- `allowPlace`
+- `allowParkour`
+- `allowParkourPlace`
+- `blockPlacementPenalty`
+- `renderCachedChunks` (and `cachedChunksOpacity`) <-- very fun but you need a beefy computer
+- `avoidance` (avoidance of mobs / mob spawners)
+- `legitMine`
+- `followRadius`
+- `backfill` (fill in tunnels behind you)
+- `buildInLayers`
+- `buildRepeatDistance` and `buildRepeatDirection`
+- `worldExploringChunkOffset`
+- `acceptableThrowawayItems`
+- `blocksToAvoidBreaking`
+
+
+
+
+# Troubleshooting / common issues
+
+## Why doesn't Baritone respond to any of my chat commands?
+This could be one of many things.
+
+First, make sure it's actually installed. An easy way to check is seeing if it created the folder `baritone` in your Minecraft folder.
+
+Second, make sure that you're using the prefix properly, and that chat control is enabled in the way you expect.
+
+For example, Impact disables direct chat control. (i.e. anything typed in chat without a prefix will be ignored and sent publicly). **This is a saved setting**, so if you run Impact once, `chatControl` will be off from then on, **even in other clients**.
+So you'll need to use the `#` prefix or edit `baritone/settings.txt` in your Minecraft folder to undo that (specifically, remove the line `chatControl false` then restart your client).
+
+
+## Why can I do `.goto x z` in Impact but nowhere else? Why can I do `-path to x z` in KAMI but nowhere else?
+These are custom commands that they added; those aren't from Baritone.
+The equivalent you're looking for is `goal x z` then `path`.
