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!
+
+**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).

-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.

 # 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:
+Commands in Baritone:
 - `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
+- `cancel` or `stop` to stop everything, `forcecancel` is also an option
 - `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. left click to path into it, right click to path on top of it.
-- `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
+- `come` tells Baritone to head towards your camera, useful when freecam doesn't move your player position.
+- `blacklist` will stop baritone from going to the closest block so it won't attempt to get to it.
+- `eta` to get information about the estimated time until the next segment and the goal, be aware that the ETA to your goal is really unprecise.
+- `proc` to view miscellaneous information about the process currently controlling Baritone.
+- `repack` to re-cache the chunks around you.
+- `gc` to call `System.gc()` which may free up some memory.
+- `render` to fix glitched chunk rendering without having to reload all of them.
+- `reloadall` to reload Baritone's world cache or `saveall` to save Baritone's world cache.
+- `find` to search through Baritone's cache and attempt to find the location of the block.
+- `surface` or `top` to tell Baritone to head towards the closest surface-like area, this can be the surface or highest available air space.
 - `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.

+ * 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

+ * <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>
