-# A visualization library for the TMK keyboard firmware
-
-This library is designed to work together with the [TMK keyboard firmware](https://github.com/tmk/tmk_keyboard). Currently it only works for [Chibios](http://www.chibios.org/)
- flavors, but it would be possible to add support for other configurations as well. The LCD display functionality is provided by the [uGFX library](https://ugfx.io/). 
-
-## To use this library as a user
-You can and should modify the visualizer\_user.c file. Check the comments in the file for more information.
-
-## To add this library to custom keyboard projects
-
-1. Add tmk_visualizer as a submodule to your project
-1. Set VISUALIZER_DIR in the main keyboard project makefile to point to the submodule
-1. Define LCD\_ENABLE and/or LCD\_BACKLIGHT\_ENABLE, to enable support
-1. Include the visualizer.mk make file
-1. Copy the files in the example\_integration folder to your keyboard project
-1. All other files than the callback.c file are included automatically, so you will need to add callback.c to your makefile manually. If you already have a similar file in your project, you can just copy the functions instead of the whole file.
-1. Edit the files to match your hardware. You might might want to read the Chibios and UGfx documentation, for more information.
-1. If you enable LCD support you might also have to write a custom uGFX display driver, check the uGFX documentation for that. You probably also want to enable SPI support in your Chibios configuration.
