Grind the beans.
You can also grind them in a top pouring cup for a lower center of gravity. I recommend grinding on a level stable surface or sitting down and locking the cup between the knees (most comfortable) for an extra grip.
Grinding is by far the hardest part of the entire coffee-making process and takes about 2 minutes. Some of the beans and pieces might be flying out as you grind, so be ready for that.
