+Ergonomic PSeudo SPlit 75-key Keyboard. Desinged after two years of working with a [Truly Ergonomic CLEAVE Keyboard](https://trulyergonomic.com) and also inspired by the [Redox Keyboard](https://github.com/mattdibi/redox-keyboard).
+I am using and the [NOTED](https://neo-layout.org/Layouts/noted/) layout and the [ReNeo](https://neo-layout.org/Einrichtung/reneo/) software which offers additional possible key functions and layers.
+
+* Keyboard Maintainer: [Henning Cordes](https://github.com/hen-des)
+* Files: [https://github.com/hen-des/epssp75](https://github.com/hen-des/epssp75)
+
+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).
+
+Detailed [description](https://hen-des.github.io/epssp75/index.html) and expiriences of the conception and manufacturing.
+
+## Bootloader
+
+Enter the bootloader in 2 ways:
+
+* **Bootmagic reset**: Hold down the key at (0,0) in the matrix (usually the top left key or Escape) and plug in the keyboard
+* **Physical reset button**: Briefly press the button on the back of the PCB - some may have pads you must short instead
