How can I find out what I can use my items/resources to make?

[Chewett]

I have a lot of items and resources but don't know what I could do with them. Is there a helpful page or something?

Go to your Items Inventory and click on the Correlations button at the top.  This will show you what your various resources can be used to make.  To find out what tools do, you need to find a place that they can be used in-game, to harvest the appropriate resource - or just ask someone.
