 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.

 # 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.
-
-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 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).

 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:
