 The texture for the winter leaves (the snowy ones) is taken from Moontest,
 which can be found at https://github.com/Amaz1/moontest/tree/master/mods/moontest
 
+
+*Autum and winter leaves*
+
+Fallen autumn leaves and winter leave blocks for trees can be enabled:
+    `moresnow.enable_autumnleaves = true`
+They're pretty decorative.
+
+
+*Wool covers*
+
+The wool covers used to be defined for each wool color seperately. Many
+nodes were created. That's not ideal for servers.
+
+If you did use an older version of the moresnow mod *and* players have
+used the wool layers for building, please set
+    `moresnow.enable_legacy_wool = true`
+
+All others are better off with just setting
+    `moresnow.enable_wool_cover = true`
+
+The new version creates nodes of the type `moresnow:wool_multicolor`.
+You can craft them like this:
+    `wool:white default:stick -`
+    `     -          -        -`
+    `     -          -        -`
+
+There are 64 colors available.
+
+Note: In the following craft receipes,
+      `m` stands for `moresnow:wool_multicolor`, and
+      `d` stands for a dye of any color
+
+In order to craft the one approximating wool colors best, craft:
+    `m d -`
+    `- - -`
+In order to get the darker variant, craft:
+    `m - d`
+    `- - -`
+In order to get plain colors (i.e. `red`, `blue`, ...), craft:
+    `m - -`
+    `- d -`
+In order to get pastel colors, craft:
+    `m - -`
+    `- - d`
+As there are 64 colors available and only 15 wool and dye colors, the
+extra four colors can be crafted by replacing the dye in the craft
+receipe above with `wool:white`.
+
+Usage: Wield `moresnow:wool_multicolor` and place it either on flat
+ground for a carpet, on a stair, a slab, an inner or outer stair,
+a microblock or a panel. Less shapes than for moresnow are supported.
+After you've placed the wool layer and it has adjusted to the shape
+below, you can remove the stair or slab etc. that gave the wool its
+shape and replace that node with something else to your liking.
+Unlike the snow and leaves nodes, the wool is not a falling node and
+will stay where it is.
+
+
+*Snow cannon*
+
+The snow cannon is an easy way to cover an area (usually 8x8) with
+snow without having to place it manually. Set
+    `moresnow.enable_snow_cannon  = true`
+in order to enable the snow cannon as such.
+
+If you set
+    `moresnow.crazy_mode          = true`
+then the snow cannon can be set into a mode where it shoots snowballs
+randomly around. They may land quite far away from the cannon. It is
+very fun to watch but perhaps not ideal for servers.
