+![Binepad KnobX1](https://i.imgur.com/9HeFQXP.png)
+
+*A fully customizable knob designed to enhance your PC experience*
+
+* Keyboard Maintainer: [binepad](https://github.com/binepad)
+* Hardware Supported: *Binepad knobX1*
+* Hardware Availability: [binepad.com](https://binepad.com/products/knobx1)
+
+Make example for this keyboard (after setting up your build environment):
+
+ make binepad/knobx1:default
+
+Flashing example for this keyboard:
+
+ make binepad/knobx1:default:flash
+
+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).
+
+## Bootloader
+
+Enter the bootloader in 2 ways:
+
+* **Bootmagic reset**: Hold down the layer button (small button on the bottom left) and plug in the keyboard.
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
