+## Docker
+
+If you are looking to setup YoutubeDL-Material with Docker, this section is for you. And you're in luck! Docker setup is quite simple.
+
+1. Run `curl https://github.com/Tzahi12345/YoutubeDL-Material/releases/latest/download/docker-compose.yml -o docker-compose.yml` to download the latest release of `docker-compose.yml`, or go to the [releases](https://github.com/Tzahi12345/YoutubeDL-Material/releases/) page to grab the version you'd like.
+2. Modify the config items in the `environment` section of `docker-compose.yml` to your liking. Otherwise, the default options will work and point to `http://localhost:8998`. You can find an explanation of these configuration items in [Configuration](#Configuration) section. 
+3. Make sure the port in the `frontend_url` environment variable lines up with the port in the `ports` section.
+4. Run `docker-compose pull`. This will download the official YoutubeDL-Material docker image.
+5. Run `docker-compose up` to start it up. If successful, it should say "HTTP(S): Started on port 17442" or something similar. Make sure you can connect to the frontend, and if so, you are done!
