 ## Building
 
+This repo holds multiple versions of images depending on the opencl implementation being used. The following set of commands shows how to build each one.
 
+```bash
+docker build -t <image name> --build-arg "aparapiver=<aparapi Version>" amdgpu/
+docker build -t <image name> --build-arg "aparapiver=<aparapi Version>" nvidia/
+
+```
+
+## Running
+
+To run the amdgpu-pro image you must have compatible hardware and drivers installed. To do so execute the following command.
 
 ```bash
-docker build --device /dev/dri:/dev/dri -t <image name> --build-arg "aparapiver=<aparapi Version>" amdgpu/
-docker build --device /dev/dri:/dev/dri -t <image name> --build-arg "aparapiver=<aparapi Version>" nvidia/
+docker run --device /dev/dri -it aparapi/aparapi-amdgpu:latest bash
+```
+
+To run the NVIDIA based OpenCL implementation you can run the following command presuming you have the [NVIDIA Container Toolkit](https://github.com/NVIDIA/nvidia-docker) installed as well as the appropriate drivers.
+
+```bash
+docker run --runtime=nvidia -it aparapi/aparapi-nvidia:latest bash
+```
+
+### Using as a Gitlab Runner
+
+If you wish to use this container as an image for use in a GitLab CI when setting up your own runner then the following config.toml will serve as an example. Ensure you select an AMI which has the 
+[NVIDIA Container Toolkit](https://github.com/NVIDIA/nvidia-docker) installed and the instance type is GPU-accelerated with NVIDIA hardware (most are). Both of which are the case in the below example. Don't forget
+to also change the MachineOptions and other values to appropriate values.
