   - `save_name` - This parameter controls the name of the save file this script will use to start the server.
-  - `experimental` - This parameter controls if the script will download the latest build or the experimental build of the game. See the [Factorio download page](https://www.factorio.com/download) for more information.
+  - `version` - This parameter controls what version of Factorio the script will download. See the [Factorio archived downloads page](https://factorio.com/download/archive/) for a list of versions.
+    - Set this parameter to `stable` if you want the most recent stable release of the game, and `latest` if you want the most recent experimental release.
   - If you have modified any default config files except for the `config.ini`, you'll want to change the commands' parameters to match those files. I'll assume you're storing them in the `./data` directory. You can find more arguments on the [Factorio Wiki](https://wiki.factorio.com/Command_line_parameters).
     - `extra_params_create=""` - This parameter adds additional flags to the `--create` command the script runs if a save matching `save_name` is not found.
