Garlic Shrimp Pasta

1 Boil pasta in water till tender, save 1 cup of pasta water for use later. I always put some oil, salt, and fresh herbs in with my pasta when I boil it. Drain and set aside when done.
2 While pasta is boiling, wash shrimp.
3 Melt butter over medium heat. Add shrimp.
4 Let cook till a little pink and starting to curl. Then add garlic.
