Compendium
The Compendium is your main resource for tracking everything in the game.
The Compendium is broken down into 7 main sections: Items, Cargo, Creatures, Resources, Structures, Collection, and Knowledge. Each section includes a search feature, which allows you to quickly access whatever you're trying to find.
On the Items, Cargo, and Structures sections, you'll be able to see the Info, Obtain, and Use tabs for each recipe you've unlocked. As you progress, anything that could potentially unlock new recipes will have a yellow "?" beside it. If you see an item like this in storage, it's generally recommended to move it to your inventory to unlock the recipes and then place it back.
You can quickly open the Compendium at any time by pressing the C key. You can also hover over an item with your cursor and then hold the Alt key and left click the item. This will open the Compendium displaying that specific item's page.
