How do I use Bottarga di Tonno when cooking spaghetti? - tonno tuna

One of my colleagues went to Rome, and I love cooking, I asked him to bring some Italian ingredients. One thing I got was a pot of something called litle bottarga di tonno, I said, it is a dry powder and salted tuna roe. I know that if you can cook spaghetti, but can someone me a recipe?
