 By some stroke of luck, you've made your way here. The Ploopy Mouse. Your life will never be the same.
 
-This repository contains the schematic for the Ploopy Mouse. If you're looking for Ploopy Mouse firmware, check out the [Ploopy Mouse QMK fork](https://github.com/ploopyco/qmk_firmware) (this is also a valid target for your QMK build environment).

+This repository contains the schematic for the Ploopy Mouse. If you're looking for the firmware that gets shipped with every mouse, check out the [Ploopy Mouse QMK fork](https://github.com/ploopyco/qmk_firmware) (this is also a valid target for your QMK build environment).
+
+QMK code for the Ploopy Mouse has been integrated into the [master of the QMK repository](https://github.com/qmk/qmk_firmware). If you prefer to get the latest code, look there. However, only code found in the official [Ploopy Mouse QMK fork](https://github.com/ploopyco/qmk_firmware) is guaranteed to be stable.
 
 What are you waiting for? Your new life awaits.
 
 ## Under what license is this released?
 
 The firmware is released under GPLv3, as per the license requirements set out in the original [QMK firmware](https://github.com/qmk/qmk_firmware). The PCB schematic is released under OHL CERN v1.2. Check the respective LICENSE.md files for full license text.

+# How to Flash New Firmware
+
+The Ploopy Mouse is fairly easy to program and reprogram, thanks to the excellent work by all of the developers and maintainers of the [QMK firmware suite](https://github.com/qmk/qmk_firmware). This guide will focus specifically on flashing firmware to the Ploopy Mouse.
+
+## Before you begin
+
+If you have never used QMK before, go through [all of the steps in the QMK guide to set up your environment](https://docs.qmk.fm/#/newbs_getting_started).
+
+QMK was built for keyboards, so you'll see lots of references to code that looks like the following:
+
+`-kb <keyboard>`
+
+Whenever you see that, use the following syntax:
+
+`-kb ploopyco/mouse`
+
+and you'll be fine.
+
+## Building the Ploopy Mouse firmware
+
+With your terminal window open and pointed at your QMK build environment, compile the firmware with the following command:
+
+`qmk compile -kb ploopyco/mouse -km via`
+
+Alternatively, you can invoke the Makefile directly with the following:
+
+`make ploopyco/mouse:via`
+
+If you wish, you can use the default keymap (with `qmk compile -kb ploopyco/mouse -km default` or `make ploopyco/mouse:default`). However, the VIA keymap is particularly interesting because it allows for customization of the mouse's functions without reflashing the firmware, through the use of the convenient [VIA software package](https://github.com/the-via/releases/releases). It's incredibly handy, so definitely check it out.
+
+For more details on building QMK firmware in general, see the [QMK firmware guide](https://docs.qmk.fm/#/newbs_building_firmware).
+
+## Putting the Ploopy Mouse into bootloader mode
+
+Putting the Ploopy Mouse into bootloader mode is very easy.
+
+1. Unplug it from your computer.
+2. Hold the "back" button. This is the button on the side of the mouse that is closer to the bottom of your hand.
+3. While holding the back button, plug the Ploopy Mouse into your computer. If you're using QMK Toolbox, it should show up in the console. If using `dmesg`, it'll show up as an Atmel DFU device.
+
+And that's it. While plugged in this way, the Ploopy Mouse will accept new firmware.
+
+## Flashing the firmware
+
+Use your preferred method of flashing QMK firmware.
+
+- QMK Toolbox has been verified as working.
+- Using `dfu-programmer` from a terminal window has also been verified as working.
+
+For more details, see the [QMK guide](https://docs.qmk.fm/#/newbs_flashing) on flashing firmware.
+
+## And that's it!
+
+Unplug it, replug it in, and you should be good to go!
+
+Happy customizing!
