 # 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).
+`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`.
 
@@ -26,11 +40,11 @@ Some common examples:
 - `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 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 diamond_ore 64`.
 - `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. `followplayers` to follow any players in range (combine with Kill Aura for a fun time). `followentities` to follow any entities. `followentity pig` to follow entities of a specific type.
-- `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).
+- `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 just straight ahead and make a tunnel
+- `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
 - `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.
