 # Fresh: Keeping your docker stacks up to date
 
 Fresh was written to scratch an itch. It works by querying the respective repositories
-returning
+for the various manifests in order to determine if the images have been changed. If so
+it can do a combination of things:
+
+- Set the exitcode to indicate the freshness, `0` means up-to-date and `1` outdated.
+- Pull the updated images with docker-compose, and optionally recreate the containers
+  with `docker-compose up`.
+- Run a script before and after updating, f.ex. to enable maintenance mode or update
+  permission on volumes.
+- Notify webhooks when updating. Currently only Slack and Mattermost are supported.
+
+Fresh is designed to be invoked using cron or systemd timers, and as such provides
+a light-weight easy-to-use alternative to more complex toolkits.

 - **What are these hashes?** Fresh grabs the manifest for the image from the registry
   and proceeds to hash a concatenation of all the various build layer hashes. This
   should mean if the image is new but the layers are the same nothing will be updated.
+- **How do I notify a Mattermost webook?** Mattermost webhooks are compatible with
+  Slack webhooks, so simply use the `--slack` flag.
