Menus.md

+MCCosmetics menus can be edited to look however you'd like!
+
+Each menu's config file is located in the `plugins/MCCosmetics/menus` folder. There are two main types of menus:
+  * `customize.yml` - *The /customize menu, with a list of cosmetic types*
+  * `selection.yml` - *Menus for selecting specific cosmetics*
+
+Selection menus can also exist as `selection_[cosmeticType].yml` to customize the menu for each cosmetic type. If no type-specific menu exists, it will use the regular selection.yml generic menu.
+
+## Basic Menu Configuration
+A default menu file looks something like this:
+```
+Menu:
+  Display: "            &c&lMCCosmetics"
+  Size: 27
+  Schema:
+  - 1 1 1 1 1 1 1 1 1
+  - 1 H B A E S O 0 1
+  - 1 1 1 1 1 1 1 1 1
+  Icons:
+    FANCY_BORDER:
+      Mapping: 1
+      Material: BLACK_STAINED_GLASS_PANE
+      Display: ''
+      Model: 1
+```
+
+The layout of the menu is defined by the `Schema`. Each letter in the schema is mapped to an icon listed under the `Icons` configuration, where `Mapping` is the letter the icon will map to in the schema.
+
+### Customize Menu
+
+In the customize menu, buttons with specific names will open the corresponding selection menu for each cosmetic type. These buttons should be named `BUTTON_[TYPE]`, e.g. `BUTTON_HATS` would open the hats selection menu.
+
+These mappings will work even for custom cosmetic types registered through the API.
+
+### Selection Menu
+
+You may notice the selection menus contain `$` symbols. These designate where any dynamic data will be loaded, in this case the list of different cosmetics.
+
+The selection menus can also contain the following special buttons:
+  * **`BUTTON_BACK`** - *Will go back to the customize menu*
+  * **`NEXT_PAGE`** - *Will move the data forward a page*
+  * **`PREVIOUS_PAGE`** - *Will move the data back a page*
