 * Keyboard Maintainer: [Holten Campbell](https://github.com/holtenc)
 * Hardware Supported: STM32F072CBT6
 
-Make example for this keyboard (after setting up your build environment):
+## Compiling firmware and flashing
 
-    make primekb/meridian:default
+### Enter bootloader
+
+The DFU state in the bootloader can be accessed in 3 ways:
+
+* **Bootmagic reset**: hold down the key at (0,0) in the matrix (usually Escape) and plug in the keyboard; or
+* **Physical reset button**: press the button on the bottom of the PCB; or
+* **Keycode in layout**: press the key mapped to `RESET` if it is available (Escape key on layer 1 in the default layout).
+
+### Compile firmware
+
+The Meridian PCB was delivered in two variants, equal in design but using different RGB LED models: one using WS2812 and another using KTR1010 LEDs. Both can be compiled using
+
+    make primekb/meridian/ws1812:default
+    make primekb/meridian/ktr1010:default
+
+After compiling, enter bootloader in the PCB and flash the firmware using `dfu-util` or QMK Toolbox. For direct compile-and-flashing, put the PCB in DFU state and use
+
+    make primekb/meridian/ws1812:default:flash
+    make primekb/meridian/ktr1010:default:flash
+
+VIA-supported firmwares are also available.
