 ##### Running tests
 
-To run tests you can use the helper top level Makefile
+Running the unit tests has been significantly simplified for contributors.
 
-For visual studio you can run
+The tests run on CPU, and can be triggered using the ACT command line interface (https://github.com/nektos/act) - once you install the command line (And start the Docker daemon) you just have to type:
 
 ```
-make vs_cmake
-make vs_run_tests VS_BUILD_TYPE="Release"

-For unix you can run
+The repository contains unit tests for the C++ and Python code, and can be found under the `test/` and `python/test` folder.
 
-```
-make mk_cmake MK_BUILD_TYPE="Release"
-make mk_run_tests
-```
+The tests are currently run through the CI using Github Actions. It uses the images found in `docker-builders/`.
+
+In order to minimise hardware requirements the tests can run without a GPU, directly in the CPU using [Swiftshader](https://github.com/google/swiftshader).
+
+For more information on how the CI and tests are setup, you can go to the [CI, Docker and Tests Section](https://kompute.cc/overview/ci-tests.html) in the documentation.
