+# landingpage
+
+The public face of my server. 
+Not much to see here honestly,
+just a few simple lines of html explaining what this server is about and how to contact me.
+
+I don't see anybody else benefiting massively from this role but me, 
+but if you want the same web presence go for it I suppose 😉
+
+## Defaults
+
+```
+landingpage_upstream_file_dir: "{{ docker_stack_files_dir }}/{{ stack_name }}"
+```
+
+The on-target directory where the proxy configuration file should be stashed.
+
+```
+landingpage_use_https: true
+```
+
+Whether the service should be reachable through http (port 80) or through https (port 443) and provision an https certificate. Usually you will want this to stay `true`.
+
+```
+landingpage_version: latest
+```
+
+The docker image version to be used in stack creation.
+
+```
+subdomain_alias: www
+```
+
+If the deployed container should be served over a uri that is not the stack name. 
+By default, it will be set to `www.yourdomain.com` - 
+if this option is not set it will be served on `landingpage.yourdomain.com` instead.
