-bluepad keyboard firmware
-======================
+# LFKPad
 
-## Quantum MK Firmware
+![LFKPad](https://cdn11.bigcommerce.com/s-dvx2zpcx7r/images/stencil/500x659/products/118/385/img_0256__06462.1546304848.jpg)
 
-For the full Quantum feature list, see [the parent readme.md](/docs/README.md).
+Hotswap 21-key numpad PCB with USB-C, per-key RGB and underglow.
 
-## Building
+* Keyboard Maintainer: QMK community
+* Hardware Supported: LFKPad HS21 PCB
+* Hardware Availability: [LFKeyboards](https://www.lfkeyboards.com/lfkpad/)
 
-Download or clone the whole firmware and navigate to the keyboards/bluepad folder. Once your dev env is setup, you'll be able to type `make` to generate your .hex - you can then use the Teensy Loader to program your .hex file. 
+Make example for this keyboard (after setting up your build environment):
 
-Depending on which keymap you would like to use, you will have to compile slightly differently.
+    make lfkeyboards/lfkpad:default
 
-### Default
-
-To build with the default keymap, simply run `make`.
-
-### Other Keymaps
-
-Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create a folder with the name of your keymap in the keymaps folder, and see keymap documentation (you can find in top readme.md) and existant keymap files.
-
-To build the firmware binary hex file with a keymap just do `make` with `keymap` option like:
-
-```
-$ make keymap=[default|jack|<name>]
-```
-
-Keymaps follow the format **__keymap.c__** and are stored in folders in the `keymaps` folder, eg `keymaps/my_keymap/`
+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).
