 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).

+"wtf where is goto death, goto waypoint" -> look at `#help wp` (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` (remember stuff is clickable!).

 **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).
+`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`.
