+# N.B.: The CMake project needs to be reloaded every time a new source file is created

+# Setup Instructions (CLion):
+# Create a new CLion project
+# Set cmake_minimum_required on line 38 to the version of cmake you are using e.g. "cmake_minimum_required(VERSION 3.17)"
+# Set the name on line 60 of this file to the CLion project name you set above e.g. "project(Week4_task C)"
+# Copy this and generic-gcc-avr.cmake into the root folder of the CLion project overwriting any conflicts
+# Reload the CMake project in CLion
+#
+# Setup Instructions (general):
+# Set cmake_minimum_required on line 38 to the version of cmake you are using e.g. "cmake_minimum_required(VERSION 3.17)"
+# Set the name on line 60 of this file to anything you like e.g. "project(Week4_task C)"
