+Reboot Logic Unittest
+=======
+
+These tests were written with Catch2 and VS code.
+Install VS code with the C++ and CMake plugins and open this folder with VS code.
+You should be able to run the tests directly.
+
+It is also recommended to [install Catch2](https://github.com/catchorg/Catch2/blob/devel/docs/cmake-integration.md):
+
+```sh
+git clone https://github.com/catchorg/Catch2.git
+cd Catch2
+git checkout v3.0.0-preview4
+cmake -Bbuild -H. -DBUILD_TESTING=OFF
+sudo cmake --build build/ --target install
