+## Add additional .ini files
+
+PHP has been configured at compile time to scan the `/opt/bitnami/php/etc/conf.d/` folder for extra .ini configuration files so it is also possible to mount your customizations there.
+
+For example, you can override the default `max_file_uploads` setting by doing the following:
+
+1. Create a file called _custom.ini_ with the following content:
+
+```
+max_file_uploads = 30M
+```
+
+2. Run the php-fpm container mounting the custom file.
+
+```bash
+$ docker run -it -v /path/to/custom.ini:/opt/bitnami/php/etc/conf.d/custom.ini bitnami/php-fpm php -i | grep max_file_uploads
+
+```
+
+You should see that PHP is using the new specified value for the `max_file_uploads`.
