+BTT Octopus Pin Aliases
+=========
+
+This file defines a set of pin aliases for the [Bigtreetech Octopus](https://github.com/bigtreetech/BIGTREETECH-OCTOPUS-V1.0) controller. This can make setting up your Klipper config easier by using familiar names instead of odd MCU pin IDs.
+
+## Installation:
+You can either copy the contents of this config to you printer.cfg add it as a separate file and import it using:
+`[include btt_octopus_pin_aliases.cfg]`
