 The build is fully deterministic and reproducible, and you can verify Travis did it properly by running `docker build --no-cache -t cabaletta/baritone .` yourself and comparing the shasum. This works identically on Travis, Mac, and Linux (if you have docker on Windows, I'd be grateful if you could let me know if it works there too).

 - **Forge Standalone**: Same as Standalone, but packaged for Forge. This should be used when Baritone is your only Forge mod, or none of your other Forge mods integrate with Baritone.
 - **Unoptimized**: Nothing is obfuscated. This shouldn't be used ever in production.
 
-## More Info
-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. 
-
-You can verify whether or not it worked by running `.b version` in chat (only valid in Impact). It should print out the version that you downloaded. Note: The version that comes with 4.5 is `v1.2.3`.

 ## Build it yourself

@@ -38,21 +40,21 @@ Some common examples:
 - `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 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.
+- `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
+- `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.
 - `version` to get the version of Baritone you're running
 - `damn` daniel
