-## 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`.

 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 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 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).
@@ -47,15 +47,23 @@ Some common examples:
 - `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.
+- `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
