Workshop

Many Steam games support the steam workshop. It is an easy way to share community maps and addons and is very useful for custom servers, without needing to worry about setting up FastDL. LinuxGSM adds workshop pre-configuration to game server scripts as when available.

You will need a Steam API key, a collection to subscribe to (you can create one), and some config parameters in your LinuxGSM config.

Getting a Steam API Key

Simply go to https://steamcommunity.com/dev/apikey and follow instructions.

Do not share this key.

Creating a collection and get the collection ID

Go browse collections for your desired game, and click "Create a collection".

Add some addons to the collection, then publish the completed collection. Then get the collection page id which can be found on the page URL. For example:

https://steamcommunity.com/sharedfiles/filedetails/?id=274397080

The collection id would be 274397080.
