+Like a lot of compose files, it's intended for use with `docker-compose`, instead of "swarm mode", but it should be a good start.
+
+First, let's create a directory with the files we need:
+
+```
+abra recipe create matomo
+cd ~/.abra/apps/matomo
+```
+
+Then, let's download and edit the `docker-compose.yml` file:
 
 ```
 mkdir matomo && cd matomo
 wget https://raw.githubusercontent.com/matomo-org/docker/master/.examples/apache/docker-compose.yml -O compose.yml

 1. Let's bump the version to `3.8`, to make sure we can use all the latest swarm coolness
 2. We load environment variables separately via [abra](/overview/#command-line-tool), so we'll strip out `env_file`.

 The resulting `compose.yml` is available [here](https://git.autonomic.zone/coop-cloud/matomo/src/branch/main/compose.yml).

+    The rest of this guide assumes you have a Co-op Cloud server going -- we'll use `swarm.example.com`, but replace it with your own server address.
+
+    Head over to [the deployment guide](./deploy.md) if you need help setting one up.
+
+Now, we're ready to create a testing instance of Matomo:
 
 ```
-TYPE=matomo
+abra app new matomo --secrets \
+ --domain matomo.swarm.example.com \
+ --server swarm.example.com \
+ --app-name mygreatapp
+ ```
 
-DOMAIN=matomo.example.com
+Depending on whether you defined any extra environment variables -- we didn't so
-LETS_ENCRYPT_ENV=production
+far, in this example -- you might want to run `abra app mygreatapp config` to
+check the configuration.
 
-SECRET_DB_PASSWORD_VERSION=v1
+Otherwise, or once you've done that, go ahead and deploy the app:
-SECRET_DB_ROOT_PASSWORD_VERSION=v1
+
+```
+abra app mygreatapp deploy
 ```
 
 Then, open the `DOMAIN` you configured (you might need to wait a while for Traefik to generate SSL certificates) to finish the set-up. Luckily, this container is (mostly) configurable via environment variables -- if we want to auto-generate the configuration we can use a `config` and / or a custom `entrypoint` (see [`coop-cloud/mediawiki`](https://git.autonomic.zone/coop-cloud/mediawiki) for examples of both).
