usually you would step it up. This way you wont need as big a starter. There is a calculator some one made or found on this site that does that.

4 secs in searching gave me the thread :p here it is Step calculator thread

Smack the Wyeast pack, wait for it to swell.
Make 5L of 1.040 wort, sanitise/sterilise wort and flask/stirbar (if the flask is borosilicate you can do all this at once by boiling the wort in the flask).
Cool wort, pitch yeast, cover flask (aluminum foil works fine).
Place on stir-plate for a couple of days.

Since you are using a full pack you don't have to step it up - assuming the pack is fairly new and healthy - the inoculation rate is well within accepted ranges. However, you did step the starter (say by making a 1L starter first) you might end up with some more healthy yeast cells at the end of the process - which would be more useful if the pack is a bit old and the yeast in it might not be in the best of shape.
