Basically, start with removing the fuel cover (carefully!) and then work your way down.
1. Fuel cover.
2. U-shaped piece (behind the fuel cover)
3. Side painted panels (there's a couple bolts under the seat for this one)
4. Footrest panels.
None of the fasteners are really hidden; it just takes a little time at first to make sure you've got everything. Also, be sure to check the spring clips before putting any panels back on. They have a tendency to fall off and there's nothing worse than getting 90% of the panels on only to realize you can't screw something down.
