+## Overriding configuration templates
+
+If you can't customize via variables because an option isn't exposed, you can override the template used to generate the virtualhost configuration files or the `nginx.conf` file.
+
+```yaml
+nginx_conf_template: "nginx.conf.j2"
+nginx_vhost_template: "vhost.j2"
+```
+
+If necessary you can also set the template on a per vhost basis.
+
+```yaml
+nginx_vhosts:
+  - listen: "80 default_server"
+    server_name: "site1.example.com"
+    root: "/var/www/site1.example.com"
+    index: "index.php index.html index.htm"
+    template: "{{ playbook_dir }}/templates/site1.example.com.vhost.j2"
+  - server_name: "site2.example.com"
+    root: "/var/www/site2.example.com"
+    index: "index.php index.html index.htm"
+    template: "{{ playbook_dir }}/templates/site2.example.com.vhost.j2"
+```
+
+You can either copy and modify the provided template, or extend it with [Jinja2 template inheritance](http://jinja.pocoo.org/docs/2.9/templates/#template-inheritance) and override the specific template block you need to change.
+
+### Example: Configure gzip in nginx configuration
+
+Set the `nginx_conf_template` to point to a template file in your playbook directory.
+
+```yaml
+nginx_conf_template: "{{ playbook_dir }}/templates/nginx.conf.j2"
+```
+
+Create the child template in the path you configured above and extend `geerlingguy.nginx` template file relative to your `playbook.yml`.
+
+```
