 Notice the naming convention for the function is 'command' followed by your desired command, in camelCase. For example, a command of `thisisalongcommand` would have a function called `commandThisIsALongCommand`.

+## Running the bot using Docker
+
+### Installing Docker
+
+If you're on Windows, visit [this website](https://docs.docker.com/docker-for-windows/install/) and download and install Docker Desktop. You'll probably need to install WSL and do some Windows updates. Once it's all installed you'll get a lovely GUI that you can use if you want to.
+
+For Mac and Linux users, Google is your friend here.
+
+### Dockerize the bot
+
+To build a docker image, open a command window in the project directory and run:
+
+`docker build -t mupbot .`
+
+For a sanity check, you can run `docker images` and it should be displayed in that list.
+
+### Running the Docker container
+
+Running the bot with --detach runs the container in detatched mode (as in it runs in the background). If you want to see what is happening, remove that option.
+
+`docker run --detach --name mupbot mupbot`
+
+You can use CTRL+C to exit out of this command window. If you're using Windows, Docker Desktop will now show your bot under 'Containers/Apps', from where you can easily stop and start it using the GUI.
+
+### Updating
+
+If doing it manually, in the folder with all the files run:
+
+```sh
+docker stop mupbot
+docker rm mupbot
+docker image rm mupbot
+docker build -t mupbot .
+docker run --detach --name mupbot mupbot
+```
