+# MechMerlin's DZ60 Keymap
+
+The purpose of this keymap is to provide examples on how to do some common QMK features. 
+
+Make example for this keyboard (after setting up your build environment):
+
+    make dz60:mechmerlin
+
+## Merlin's DZ60 Hardware Info
+---
+
+The DZ60 is a 60% pcb produced by KBDFans. It comes in two variants, USB Mini B and USB C. It supports many many layouts. It also supports both backlight and RGB underglow. The USB C variant does not have a hardware reset switch. USB C to C is not supported. 
+
+Merlin's DZ60 uses
+- Layout B, in QMK this is LAYOUT_60_b_ansi. 
+- USB C
+- 50g Zilents
+- Arrows are 78g Zilents
+- KPRepublic XD64 Case
+
+## Layers
+---
+
+Merlin's keymap has three different layers. To switch layers you can use the `MO(X)` keycode, where `X` is the layer you want to switch to. 
+
+### _BL
+
+This is the base layer also known as layer 0. It is a standard QWERTY layout. It has the `_FL` layer switch key. 
+
+### _FL
+
+This is the function layer also known as layer 1. It utiizes the following:
+- Function Keys
+- Navigation Keys
+- Audio keys such as Mute, Volume Down and Volume Up. 
+- `_CL` layer switch key 
+
+### _CL
+
+This is the control layer also known as layer 2. It utilizes the following:
+- RGB Controls
+- `RESET` key
+
+## Non Standard Keycodes
+---
+### RESET
+
+As long `BOOTMAGIC_ENABLE` is set to `yes` in `rules.mk`, the DZ60 can be put into bootloader mode by holding the `space` key and the `b` key while plugging in. However sometmes this doesn't work or is troublesome to do, might as well use the `RESET` keycode to accomplish this. 
+
+### RSFT_T(KC_SLSH)
+
+Layout B is missing the `?` key and is instead replaced with a `right shift`. This keycode makes it so that the key can be tapped for `?` and held for `right shift`. 
+
+### LCTL_T(KC_CAPS)
+
+`Caps Lock` is only ever used by tapping, why not use it as a `control` key when held? This keycode makes it so that the key can be tapped for `caps lock` and held for `control`. 
+
+
+## RGB Lighting
+---
+
+### RGBLIGHT_SLEEP
+
+This is set in `mechmerlin/config.h` so that when the computer goes to sleep, the RGB lights will also go to sleep on the keyboard. They will turn back on when the computer wakes. 
+
+### RGB Underglow Color: Yellow
+
+This is set in `mechmerlin/keymap.c` in the `matrix_init_user` function. The list of available colors can be found in [`quantum/rgblight_list.h`](https://github.com/qmk/qmk_firmware/blob/388df5359b913eaf1ce6fb0ef624e430ad010ea5/quantum/rgblight_list.h#L59-L121).
