+<p>Docker Stack expects a project file, named <code>docker-compose.yml</code>
+in a project directory. First create your project directory.</p>
+
+<pre><code>mkdir -p /{{ root }}/{redis,certs,data,dkim,mail,overrides/rspamd,filter,dav,webmail}
+</pre></code>
+
+<p>Then download the project file. A side configuration file makes it easier
+to read and check the configuration variables generated by the wizard.</p>
+

+{% call macros.panel("info", "Step 3 - Deploy docker stack") %}
+<p>To deploy the docker stack use the following commands. For more information about setting up docker swarm nodes read the
+	<a href="https://docs.docker.com/get-started">docker documentation</a></p>
+
+<pre><code>cd {{ root }}
+docker swarm init
+docker stack deploy -c docker-compose.yml mailu
+</pre></code>
+
+In the docker stack deploy command, mailu is the app name. Feel free to change it.<br/>
+In order to display the running container you can use<br/>
+<pre><code>docker ps</code></pre>
+or
+<pre><code>docker stack ps --no-trunc mailu</code></pre>
+Command for removing docker stack is
+<pre><code>docker stack rm mailu</code></pre>
+
+Before you can use Mailu, you must create the primary administrator user account. This should be {{ postmaster }}@{{ domain }}. Use the following command, changing PASSWORD to your liking:
+
+<pre><code>docker exec $(docker ps | grep admin | cut -d ' ' -f1) python manage.py admin {{ postmaster }} {{ domain }} PASSWORD 
+</pre></code>
+
+<p>Login to the admin interface to change the password for a safe one, at
+{% if admin_enabled %}
+one of the hostnames 
+<a href="https://{{ hostnames.split(',')[0] }}{{ admin_path }}">{{ hostnames.split(',')[0] }}{{ admin_path }}</a>.
+{% else %}
+<a href="http://127.0.0.1:8080">http://127.0.0.1:8080</a> (only directly from the host running docker).
