+[![Build Status](https://drone.autonomic.zone/api/badges/coop-cloud/wordpress/status.svg)](https://drone.autonomic.zone/coop-cloud/wordpress)
 
 Coöp Cloud + [Wordpress](https://wordpress.org) = 🥳
 
-1. Set up Docker Swarm and [`abra`][abra]
-2. Deploy [`compose-stacks/traefik`][compose-traefik]
-3. `cp .envrc.sample .envrc`
-4. Edit `.envrc` - be sure to change `$DOMAIN` to something that resolves to
-   your Docker swarm box
-5. `direnv allow` (or `. .envrc`)
-6. Generate secrets:
-   ```
-   abra secret_generate db_password v1
-   abra secret_generate db_root_password v1
-   ```
+<!-- metadata -->
 
-7. `abra deploy`
-8. Open the configured domain in your browser to finish set-up
-9. `abra run wordpress chown www-data:www-data /var/www/html/wp-content` to fix
+- **Category**: Apps
+- **Status**: ❶💚
+- **Image**: [`wordpress`](https://hub.docker.com/_/wordpress), ❶💚, upstream
+- **Healthcheck**: Yes
+- **Backups**: Yes
+- **Email**: ❶💚
+- **Tests**: ❷💛
+- **SSO**: No
+
+<!-- endmetadata -->
+
+## Basic usage
+
+1. Set up Docker Swarm and [`abra`][abra]
+2. Deploy [`coop-cloud/traefik`][cc-traefik]
+3. `abra app new wordpress --secrets` (optionally with `--pass` if you'd like
+   to save secrets in `pass`)
+4. `abra app YOURAPPDOMAIN config` - be sure to change `$DOMAIN` to something that resolves to
+   your Docker swarm box
+5. `abra app YOURAPPDOMAIN deploy`
+6. Open the configured domain in your browser to finish set-up
+7. `abra app YOURAPPDOMAIN run app chown www-data:www-data /var/www/html/wp-content` to fix
    file permissions (see #3)
 
+## Running WP-CLI
+
+`abra app YOURAPPDOMAIN wp 'core check-update --major'`
+
+(the WP-CLI arguments need to be quoted, because of how `abra` handles
+command-line arguments)
+
 ## Network (Multi-site)
 
 _(Only tested using subdomains)_
 
 1. Set up as above
-2. Uncomment the first `# Multisite` section in `.envrc`
-3. `direnv allow` (or re-run `source .envrc`)
-4. `abra deploy`
-5. Log into the Wordpress admin dashboard, go to Tools » Network Setup
-6. Don't worry about the suggested file changes
-7. Comment out the first `# Multisite` section in `.envrc` and uncomment the
-   `# Multisite phase 2` section
-8. `direnv allow` (or re-run `source .envrc`)
-9. `abra deploy`
-10. FIXME setting up SSL / routing
+2. `abra app YOURAPPDOMAIN config`, and uncomment the first `# Multisite` section
+3. `abra app YOURAPPDOMAIN deploy`
+4. Log into the Wordpress admin dashboard, go to Tools » Network Setup
+5. Don't worry about the suggested file changes
+6. `abra app YOURAPPDOMAIN config` again - comment out the first `# Multisite`
+   section in `.envrc`, uncomment the `# Multisite phase 2` section, and add
+   your multisite subdomain(s) to `EXTRA_DOMAINS` (beware the weird syntax..)
+7. `abra app YOURAPPDOMAIN deploy`
 
 ## Installing a custom theme
 
-`abra cp ~/path/to/local/theme wordpress:/var/www/html/wp-content/themes/`
+`abra app YOURAPPDOMAIN cp ~/path/to/local/theme wordpress:/var/www/html/wp-content/themes/`
+
+## Email
+
+There is a local or remote SMTP relay configuration available.
+
+- **local**: `COMPOSE_FILE=compose.yml:compose.mailrelay.yml`
+- **remote**: `COMPOSE_FILE=compose.yml:compose.mailrelay.yml:compose.smtp.yml`
+
+Below are the instructions for the local relay.
+
+1. Deploy [`postfix-relay`][cc-postfix-relay]
+2. `abra app YOURAPPDOMAIN config`, and uncomment the email lines; change
+   `MAIL_FROM` to make sure the domain is the same as `postfix-relay`'s
+   `$DOMAIN` or in its `$EXTRA_SENDER_DOMAINS`
+3. `abra app YOURAPPDOMAIN deploy`
