+### Far Wand
+The far wand (`worldeditadditions:farwand`) is a variant on the traditional WorldEdit wand (`worldedit:wand`). It looks like this: ![A picture of the far wand](https://raw.githubusercontent.com/sbrl/Minetest-WorldEditAdditions/master/worldeditadditions_farwand/textures/worldeditadditions_farwand.png)
+
+It functions very similarly to the regular WorldEdit wand, except that it has a _much_ longer range - which can be very useful for working on large-scale terrain for example. It also comes with an associated command to control it.
+
+### `//farwand skip_liquid (true|false) | maxdist <number>`
+This command helps control the behaviour of the [WorldEditAdditions far wand](#far-wand). Calling it without any arguments shows the current status:
+
+```
+//farwand
+```
+
+You can decide whether you can select liquids or not like so:
+
+```
+//farwand skip_liquid true
+//farwand skip_liquid false
+```
+
+You can change the maximum range with the `maxdist` subcommand:
+
+```
+//farwand maxdist 1000
+//farwand maxdist 200
+//farwand maxdist 9999
+```
+
+Note that the number there isn't in blocks (because hard maths). It is however proportional to the distance the wand will raycast looks for nodes, so a higher value will result in it raycasting further.
