Forge metal with a vv2 ingot [one of the main entry points]
If you have a vv2 ingot in your inventory, you can use it to forge metals. Just right-click it and select 'forge metal'. This will create an ore block of the type you selected. The metal will be placed in your inventory. To apply it to something, simply place it on top of an item that is already equipped with a metal block (e.g., an armor piece or weapon).
