Welcome!
To start crafting, gathering resources or processing them, you'll likely need a property where you can place various crafting stations or processing stations, depends on what you are crafting or processing. There are various crafting stations for different item types, such as weapon crafting, tools, etc.

But first of all, you'll need resources, which can be gathered at various places around the map, such as with various recycling stations scattered across the map, or mining materials at the Davis Quartz Quarry, gathering crude chemicals at the Murrieta Oil Field, or by performing a heist to get ahold of more rare items.

Various resources will need to be processed, which could be done at the Grand Banks Foundry, which will allow you to process various ores into resources required for crafting items.

🌴 There's a lot more to this, but we hope that you'll figure that out!
