+# DecenTKL NumPad
+
+![decentkl](https://github.com/bleroy/3d-junkyard/blob/main/DecenTKL/Media/DecenTKL-logo.png)
+
+*A numeric pad to go with the DecenTKL keyboard*
+
+This numeric pad also includes a 3-port USB hub, enabling the connection of the TKL
+keyboard on the back of the pad.
+
+The pad also has two Atari joystick ports.
+
+* Keyboard Maintainer: [Bertrand Le roy](https://github.com/bleroy/3d-junkyard/blob/main/DecenTKL/)
+* Hardware Supported: DecenTKL (RP2040-based)
+* Hardware Availability: Custom built but open-source
+
+Make example for this keyboard (after setting up your build environment):
+
+    make decent/numpad:default
+
+Flashing example for this keyboard:
+
+    make decent/numpad: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
+
+Press the Num key or the button on the back of the board while connecting the pad.
+
+## Special commands
+
+Num + Enter: go into bootloader mode without unplugging the keyboard
