 If you are running this script locally, my recommendation is to run it manually once, before turning on the cron job: The first run will be significantly slower than subsequent runs, and that will help you prevent overlapping during that first run.
 
+### 4) Run this script from a container
+
+This script is also available in a pre-packaged container, [mastodon_get_replies](https://github.com/nanos/mastodon_get_replies/pkgs/container/mastodon_get_replies).
+
+1. Pull the container from `ghcr.io`, using Docker or your container tool of choice: `docker pull ghcr.io/nanos/mastodon_get_replies:latest`
+2. Run the container, passing the command line arguments like running the script directly: `docker run -it ghcr.io/nanos/mastodon_get_replies:latest --access-token=<TOKEN> --server=<SERVER>`
+
+The same rules for running this as a cron job apply to running the container, don't overlap any executions.
+
+An example Kubernetes CronJob for running the container is included in the [`examples`](https://github.com/nanos/mastodon_get_replies/tree/main/examples) folder.

 ## Acknowledgments
 
 This script is mostly taken from [Abhinav Sarkar](https://notes.abhinavsarkar.net/2023/mastodon-context), with just some additions and alterations. Thank you Abhinav!
