+## Adjusting PHP ini values
+
+Sometimes you may need special [`php.ini`](https://www.php.net/manual/en/ini.list.php) values. For instance, perhaps your setup requires a bit more memory. You can add additional `php.ini` files in the values.yaml by providing `nextcloud.phpConfigs.NAME_OF_FILE`. Here's an examples:
+
+```yaml
+nextcloud:
+  phpConfigs:
+    zz-memory_limit.ini: |-
+      memory_limit=512M
+```
+
+> [!Note]
+> Be sure to prefix your file name with `zz` to ensure it is loaded at the end.

 ## Running `occ` commands
 Sometimes you need to run an [occ](https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/occ_command.html) command on the Nextcloud container directly. You can do that by running commands as the user `www-data` via the `kubectl exec` command.
