 # IMPORTANT!
-This guide is strictly for Ploopy devices that come preloaded with QMK. How do you know if your device has QMK on it? The fastest way is by plugging it in and moving the ball. If there's a two second(ish) delay before the cursor starts moving on the screen, then QMK is **NOT** present on the device. However, if there is no delay and the cursor starts moving immediately after you've plugged it in, you've got QMK on it!
+This guide is strictly for Ploopy devices that come preloaded with QMK. How do you know if your device has QMK on it? The fastest way is by using a piece of software such as [QMK Toolbox](https://github.com/qmk/qmk_toolbox). If you're running that program and plug in your Ploopy device, it'll show up as a QMK device.

+You can also try jumping into the bootloader:

+- If you've got a right-handed Ploopy Classic, hold the "forward" button and plug in the trackball. If moving the ball *doesn't* move the cursor, then you've got QMK. (Try unplugging and plugging it back in without holding the forward button just to make sure that moving the ball still works as normal.)
+- If you've got a left-handed Ploopy Classic, hold the "back" button and plug in the trackball. If moving the ball *doesn't* move the cursor, then you've got QMK. (Try unplugging and plugging it back in without holding the back button just to make sure that moving the ball still works as normal.)
 
 **You can reprogram your older Ploopy device with new QMK firmware.** The instructions for doing so are in [[Appendix D: Programming QMK on Older Ploopy Devices]].
