 # Example
 
-A extended example is in the [Example Webserver](/posts/20210326-example-webserver/) post.
+This role installs only `php-fpm`. It works best together with the [nginx role](20210326-ansible-nginx/), but you can also use it as a standalone:
+
+```yaml
+---
+- hosts: jellyfish
+  user: root
+
+  roles:
+    - role: geekoops-php-fpm
+      vars:
+        apcu_enable: true
+        apcu_shm_size: 32M
+        php_memlimit: 256M
+        php_maxuploadsize: 64M
+```
+
+A more extended example of this role together with `nginx` can be found in the [Example Webserver](/posts/20210326-example-webserver/) post.
