-This is the QMK firmware repository for the Shark, updated until [revision Alpha](https://github.com/Gondolindrim/SharkPCB/releases/tag/Alpha).
+The SharkPCB is an open-source ortholinear 40% layout designed by Gondolindrim for the AcheronProject.
 
-The SharkPCB is an Open-Hardware guidelines compliant PCB which files can be found at [this link](https://github.com/Gondolindrim/SharkPCB). Its designer and maintainer is [Gondolindrim](https://github.com/Gondolindrim).
+* Keyboard Maintainer: [Gondolindrim](https://github.com/gondolindrim)
+* Hardware Availability: you can get release Beta SharkPCBs using the JLCPCB manufacturer using the files at [its documentation](http:/acheronproject.com/pcbs/shark/shark/)
 
-See the [AcheronDocs](https://gondolindrim.github.io/AcheronDocs/shark/intro.html) page for the SharkPCB full documentation.
+## How to flash
 
-Make example for this keyboard (after setting up your build environment):
+### Enter bootloader
 
-    make acheron/shark:default
+### Release Alpha:
+
+The DFU state in the bootloader can be accessed in 2 ways:
+
+* **Bootmagic reset**: hold down the key at (0,0) in the matrix (usually the top left key or Escape) and plug in the keyboard
+* **Physical reset button**: press the button on the back of the PCB
+* **Keycode in layout**: press the key mapped to `RESET` if it is available (ESC key at layer 1 in the default layout)
+
+### Release Beta:
+
+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 the top left key or Escape) and plug in the keyboard
+* **Physical reset button**: press the button on the back of the PCB, for at least five seconds
+* **Keycode in layout**: press the key mapped to `RESET` if it is available (ESC key at layer 1 in the default layout)
+
+## Compile firmware
+
+### Release Alpha
+
+After accessing the DFU state in your PCB, build the default layout using:
+
+    make acheron/shark/alpha:default
+
+### Release Beta
+
+After accessing the DFU state in your PCB, build the default layout using:
+
+    make acheron/shark/beta:default
+
+Then download the resulting binary `*bin` file using `dfu-util` or QMK Toolbox.
