 ## How does it work?
 
-* The script iterates through each line of the `stacklist` file, skipping comments
+* The script iterates through each line of the `stacklist` file (skipping comments) or through all cli parameters
 * It fetches the latest changes from the remote git repository and checks if there are new commits
 * If there is a change it pulls the updates from the remote git repository, otherwise the entry is skipped
 * Following this, it runs `docker compose up` which builds, (re)creates and starts the containers
 
-The `stacklist` file can list either a directory containing a `docker-compose.yml` file or a precise `docker-compose` file.

+The `stacklist` file can list either a directory containing a `docker-compose.yml` file or a precise `docker-compose` file (see `stacklist.example`).
+Alternatively, the stacklist can also be passed as a list of parameters.
 
 ## Usage
 
-1. Ensure that your 'stacklist' file is up-to-date
-2. Run the script manually or create a crontab entry
