+- **GET /health** Used for liveness/readiness probes
+- **GET /hello** Returns a hello World HTML page
+- **GET /distance** Calculates distance between two randomly generated 3D points
+- **POST /action/cpu-load** Used to generate some CPU load for testing HPA 
+
+[Geo3D.postman_collection](postman_collection/Geo3D.postman_collection) can be imported in [Postman](https://www.postman.com) to try the endpoints implemented.
+
+## Testing
+
+The Go code should have unit tests, this was not done for time constraints but it is a crucial part in guranteeing the correctness of the application.
