+
+## 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 (including uwu's or owo's)
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Giving and 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
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission or consent
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+Project maintainers have the right and responsibility to immediately remove
+without any sort of dispute any issues or pull requests that do not align
+with their corresponding templates. Absolutely no leniancy shall be accepted
+with these terms.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at complaints@leijurv.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.

+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 1.15.2, [click here](https://www.youtube.com/watch?v=j1qKtCZFURM) and see description. If you need Forge 1.15.2, look [here](https://github.com/cabaletta/baritone/releases/tag/v1.5.3), follow the instructions, and get the `api-forge` jar.
+
+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)**.
 
 This project is an updated version of [MineBot](https://github.com/leijurv/MineBot/),

 # Installation
 
+The easiest way to install Baritone is to install [Impact](https://impactclient.net/), which comes with Baritone.
+
+You can also use a custom version json for Minecraft, with the [1.14.4](https://www.dropbox.com/s/rkml3hjokd3qv0m/1.14.4-Baritone.zip?dl=1) version or the [1.15.2](https://www.dropbox.com/s/8rx6f0kts9hvd4f/1.15.2-Baritone.zip?dl=1) version or the [1.16.5](https://www.dropbox.com/s/i6f292o2i7o9acp/1.16.5-Baritone.zip?dl=1) version.

-To replace out Impact 4.5's Baritone build with a customized one, build Baritone as above then copy `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"`).

 # 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.
+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`)
 
-Therefore you can use a prefix before your messages.
+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.
 
-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.
+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).
 
-**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).
+# For Baritone 1.2.10+, 1.3.5+, 1.4.2+
 
-Other clients like Kami and Asuna have their own custom things (like `-path`), and can disable direct chat control entirely.

 **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`
 
 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.)
-- `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.
+- `mine diamond_ore iron_ore` to mine diamond ore or iron 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.) An amount of blocks can also be specified, for example, `mine 64 diamond_ore`.
+- `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 select an area (`#help sel` to see what you can do with that selection).
+- `follow player playerName` to follow a player. `follow players` to follow any players in range (combine with Kill Aura for a fun time). `follow entities` to follow any entities. `follow entity pig` to follow entities of a specific type.
+- `wp` for waypoints. A "tag" is like "home" (created automatically on right clicking a bed) or "death" (created automatically on death) or "user" (has to be created manually). So you might want `#wp save user coolbiome`, then to set the goal `#wp goal coolbiome` then `#path` to path to it. For death, `#wp goal death` will list waypoints under the "death" tag (remember stuff is clickable!)
+- `build` to build a schematic. `build blah.schematic` will load `schematics/blah.schematic` and build it with the origin being your player feet. `build blah.schematic 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 and make a tunnel, 1x2. It will only deviate from the straight line if necessary such as to avoid lava. For a dumber tunnel that is really just cleararea, you can `tunnel 3 2 100`, to clear an area 3 high, 2 wide, and 100 deep.
+- `farm` to automatically harvest, replant, or bone meal crops. Use `farm <range>` or `farm <range> <waypoint>` to limit the max distance from the starting point or a waypoint. 
 - `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.

+ * The {@link IArgConsumer} is how {@link ICommand}s read the arguments passed to them. This class has many benefits:

+ * <ul>
+ * <li>Mutability. The whole concept of the {@link IArgConsumer}} is to let you gradually consume arguments in any way
+ * you'd like. You can change your consumption based on earlier arguments, for subcommands for example.</li>
+ * <li>You don't need to keep track of your consumption. The {@link IArgConsumer}} keeps track of the arguments you
+ * consume so that it can throw detailed exceptions whenever something is out of the ordinary. Additionally, if you
+ * need to retrieve an argument after you've already consumed it - look no further than {@link #consumed()}!</li>
+ * <li>Easy retrieval of many different types. If you need to retrieve an instance of an int or float for example,
+ * look no further than {@link #getAs(Class)}. If you need a more powerful way of retrieving data, try out the many
+ * {@code getDatatype...} methods.</li>
+ * <li>It's very easy to throw detailed exceptions. The {@link IArgConsumer}} has many different methods that can
+ * enforce the number of arguments, the type of arguments, and more, throwing different types of
+ * {@link CommandException}s if something seems off. You're recommended to do all validation and store all needed
+ * data in variables BEFORE logging any data to chat via {@link Helper#logDirect(String)}, so that the error
+ * handlers can do their job and log the error to chat.</li>

+ * <li>Create a new instance with the empty constructor</li>
+ * <li>Use {@code append}, {@code prepend} or {@code add<something>} methods to add completions</li>
+ * <li>Sort using {@link #sort(Comparator)} or {@link #sortAlphabetically()} and then filter by prefix using
+ * {@link #filterPrefix(String)}</li>
+ * <li>Get the stream using {@link #stream()}</li>
+ * <li>Pass it up to whatever's calling your tab complete function (i.e.
+ * {@link ICommandManager#tabComplete(String)} or {@link IArgConsumer}#tabCompleteDatatype(IDatatype)})</li>
