 ### Notes & Warnings
 
 - **This is an unsupported configuration created by the community**
-- If you're using php5, change all instances of `php7.0-fpm` to `php5-fpm` and change `/run/php/php7.0-fpm.sock` to `/var/run/php5-fpm.sock`
+- **Replace `7.3` with the PHP version you installed, e.g. if you're using Raspbian Stretch (Debian 9) replace `7.3` with 7.0`.**
+- The `php7.3-sqlite` package must be installed otherwise Networking and Querying will throw an error that it can't access the database.
