 ## Supported Distributions
 
-Should work on Debian-based distributions.
+The following distributions are supported:
+
+- Debian 11
 
 ## Required Arguments
 
-- `docker_compose__compose_file_content`: The content to deploy to the Compose file at `/ansible_docker_compose/compose.yaml`.
+For the required arguments look at the [`argument_specs.yaml`](./meta/argument_specs.yaml).
 
-## Optional Arguments
+## `hosts`
 
-- `docker_compose__env_file_content`: The content to deploy to the `.env` file at `/ansible_docker_compose/.env`.
-- `docker_compose__configuration_files`: A list of configuration files to deploy to the `/ansible_docker_compose/configs/` directory.
-- `docker_compose__configuration_files.*.name`: The name of the configuration file.
-- `docker_compose__configuration_files.*.content`: The content to deploy to the configuration file.
+The `hosts` for this role need to be the machines, for which you want to make sure the given Compose file is deployed and all services of it are up-to-date and running.
