+![Matrix 8XV1.2 OG](https://i.imgur.com/NELL6Sbl.jpg)
 
-This was the Matrix 8XV1.2 OG keyboard made by the Matrix team. Note: this firmware only support ISO/ANSI version,
-and DO NOT support the 8XV1.2 OG ANSI only version.
+This was the Matrix 8XV1.2 OG keyboard made by the Matrix team.  
 
-* Keyboard Maintainer: [astro](https://github.com/yulei)
-* Hardware Supported: Matrix 8XV1.2 OG (ISO/ANSI) keyboard
-* Hardware Availability: Matrix Lab
+There are two versions of the PCB available.
 
-Make example for this keyboard (after setting up your build environment):
-
-    make matrix/m12og:default
-
-See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).

+# Matrix 8XV1.2 OG keyboard
+
+![Matrix 8XV1.2 OG](https://i.imgur.com/NELL6Sbl.jpg)
+
+This was the Matrix 8XV1.2 OG keyboard made by the Matrix team.  
+Note: This firmware only supports ANSI only version (green/yellow PCB), and DOES NOT support the 8XV1.2 OG ISO/ANSI version.
+
+* Keyboard Maintainer: [kb-elmo](https://github.com/kb-elmo)
+* Hardware Supported: Matrix 8XV1.2 OG ANSI only PCB
+* Hardware Availability: Matrix Lab
+
+Make example for this keyboard (after setting up your build environment):
+
+    make matrix/m12og/rev1:default
+
+---
+**Bootloader:**  
+
+Hold down ESC while plugging in the keyboard. The board will show up as a mass storage device on your computer. Drag and drop the compiled firmware .bin file into it. The board will automatically reset and load the new firmware.  
+
+:no_entry: **DO NOT DO THIS ON A MAC OS SYSTEM! IT WILL PERMANENTLY BRICK THE KEYBOARD!!!**
+
+---
+
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
