 A gasket-mounted 60% in the style of the S7 Elephant.
 
 * Keyboard Maintainer: [The QMK Community](https://github.com/qmk)
-* Hardware Supported: Piggy60 PCB "rev1" (atmega32u4)
-  * **Make sure your PCB uses an `atmega32u4` before flashing!** A PCB that uses an `APM32F103CBT6` with `uf2boot` has been shipped with some extras purchases and to replace some defective units. Flashing that PCB with "rev1" firmware may result in a non-functional PCB which can only be recovered using a hardware programmer (e.g. an ST-Link V2)
-* Hardware Availability: Group Buy took place between 2021-05-22 1600 UTC and 2021-05-25 1600 UTC on [https://jackylab.com/](https://jackylab.com/).
+* Hardware Supported:
+  * Piggy60 PCB rev 1 (atmega32u4, atmel-dfu)
+  * Piggy60 PCB rev 2 (APM32F103CBT6, uf2boot)
+  **Check your PCB before flashing!** Loading rev1 firmware on a rev2 PCB may result in a non-functional PCB which can only be recovered using a hardware programmer (e.g. an ST-Link V2)

 ## Bootloader
 
 Enter the bootloader in 3 ways:
 
-* **Bootmagic reset**: Hold down the top left key and plug in the keyboard. This will also clear EEPROM, so it is a good first step if the keyboard is misbehaving.
-* **Physical reset**: Short the set of vertical holes on the third row, to the right of Caps Lock. These can be reached with tweezers after the board has been assembled.
+* **Bootmagic reset**: Hold down the top left key and plug in the keyboard. This will also clear EEPROM/emulated EEPROM, so it is a good first step if the keyboard is misbehaving.
+* **Physical reset**:
+  - Rev 1: Short the set of vertical holes on the third row, to the right of Caps Lock. These can be reached with tweezers after the board has been assembled.
+  - Rev 2: Near the MCU there are two square pads with a circle in the middle. This is an unpopulated footprint for a reset button. Short these two pads twice in quick succession.
 * **Keycode in layout**: There is no key mapped to `QK_BOOT` in the pre-created keymaps, but you may assign this key in any keymaps you create.
+
+## Flashing
+
+After entering the bootloader through one of the three methods above:
+
+- Rev 1: The keyboard will appear as an Atmel DFU device. It can be flashed using the QMK CLI or QMK Toolbox.
+- Rev 2: The keyboard will appear as a USB mass storage device named `MT.KEY`. If the CLI is unable to find this device, the compiled `.uf2` file can be manually copied to it. The keyboard will reboot on completion with the new firmware loaded.
