lets put a little more detail behind what users can expect:

START WITH WALLET CLOSED

1. drop bootstrap.dat in datadir directory
2. launch mintcoin
3. you will have a loading screen saying "importing bootstrap"
4. import time varies between computers but a modern computer will take about a day and half to import
5. bootstrap will auto rename once completed
6. if bootstrap is renamed and wallet doesn't load, you can force quit and relaunch (we are aware of certain instances where it will hang, and it will be addressed in next release)
