 Running Lidarr in a Docker container eases setup and reduces package installation on the host OS. Docker is available on many platforms see the [Docker overview page](https://www.docker.com/products/overview) and install Docker before setting up a Lidarr under Docker. Once Docker is installed you'll need to want to pull the image with `docker pull linuxserver/lidarr ` and then create the container. See https://hub.docker.com/r/linuxserver/lidarr/ for the options available when creating the image.
