 `dnsr` is deployed as a Docker container. You can use the following command to run it:
 
 ```bash
-docker run -d -p 8053:8053/udp -v ./config.yml:/etc/dnsr/config.yml -v ./domains.yml:/etc/dnsr/domains.yml -v ./keys:/etc/dnsr/keys ghrc.io/thibault-cne/dnsr:latest

-The `domains.yml` file is used to configure the domains that the `dnsr` server will handle. In the following example, the `dnsr` server will handle the `example1.com`, `example2.com`, and `example3.com` domains:
 
-```yaml
----
-domains:
-  - example1.com
-  - name: example2.com
-  - name: example3.com
-    # The file name of the TSIG key for the domain.
-    # The file is located in the `tsig_folder` folder.
-    # This is optional. If not provided, the key file will be named after the domain name in snake case.

-**Note:** The `dnsr` server constantly whatches the `domains.yml` file for changes. If the file is modified, the server will reload the domains (e.g. add or remove domains).
