+# Ploopyco Madromys Trackball
+
+It's a DIY, QMK-powered trackball!
+
+* Keyboard Maintainer: [PloopyCo](https://github.com/ploopyco)
+* Hardware Supported: RP2040
+* Hardware Availability: [Store](https://ploopy.co), [GitHub](https://github.com/ploopyco)
+
+Make example for this keyboard (after setting up your build environment):
+
+    qmk compile -kb ploopyco/madromys -km default
+
+# Building Firmware
+
+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).
+
+# Triggering the Bootloader
+
+[Do you see those two golden holes in the board](https://ploopy.co/wp-content/uploads/2023/11/boot.jpg)? Those are called **vias**. They act exactly like a switch does. Right now, that switch is OFF. However, if you take a paperclip or a pair of metal tweezers and touch those two vias, the two vias will form an electrical connection. Effectively, that switch turns ON.
+
+Go ahead and connect the two vias, and then (while the vias are connected) plug in the Madromys board into your computer.
+
+The computer should recognise that a mass storage device was just plugged in. Once this is done, you should be able to drag and drop files onto the Madromys board, as if the board was a USB drive. Feel free to remove the tweezers or paperclip at this point.
+
+If you want to upload a new firmware file (a ".uf2" file, like "madromys_awesome_version.uf2" or something), just drag it into the folder, and it'll automatically install on the Madromys board and restart itself, in normal operating mode. You're done!
+
+**TIP**: If your firmware is in some kind of strange state and uploading new firmware isn't fixing it, try uploading [a flash nuke](https://learn.adafruit.com/getting-started-with-raspberry-pi-pico-circuitpython/circuitpython#flash-resetting-uf2-3083182) to the Madromys board before flashing the new firmware. It wipes the memory of the Madromys board completely clean, which can help clear a few types of errors.
+
+# Drag Scroll
+
+Drag Scroll is a custom keycode for Ploopy devices that allows you to hold or tap a button and have the mouse movement translate into scrolling instead. 
+
+Nothing needs to be enabled to use this functionality; it's enabled on Madromys by default.
+
+### Drag Scroll Configuration
+
+* `#define PLOOPY_DRAGSCROLL_MOMENTARY` - Makes the key into a momentary key, rather than a toggle.
+* `#define PLOOPY_DRAGSCROLL_MULTIPLIER 0.75` - Sets the DPI multiplier to use when drag scroll is enabled. 
+* `#define PLOOPY_DRAGSCROLL_FIXED` - Normally, when activating Drag Scroll, it uses a fraction of the current DPI. You can define this to use a specific, set DPI rather than a fraction of the current DPI. 
+  * `#define PLOOPY_DRAGSCROLL_DPI 100` - When the fixed DPI option is enabled, this sets the DPI to be used for Drag Scroll.
+* `#define PLOOPY_DRAGSCROLL_INVERT` - This reverses the direction that the scroll is performed. 
+* `#define PLOOPY_DRAGSCROLL_SEMAPHORE` - This is a divisor on the drag scroll sensitivity. The default is 0, which means that the drag scroll is at maximum sensitivity. A value of 4 would mean that the drag scroll is 4 times less sensitive.
