After transferring the crust to your pie tin, make the edges pretty - see below for tips on transferring, and fluting ideas.
To perfectly size the parchment paper, take a big piece, fold in half, then fold in half the long way, and then keep folding the short corners together while keeping the middle of the sheet to the side. You should end up with a triangle. Hold the tip of the triangle over the centre of the pie crust, and cut around the edge to the same length as the interior of the pie crust. When you unfold the parchment paper, it should magically be very close to a perfectly-sized circle. This is known as a cartouche. Some pedantic people might say it's not. They're wrong.
Cover with parchment paper and add some pie weights or an identical pie tin and weigh it down with something like a ramekin. Bake until the edges are lightly browned, Anywhere from 7-15 minutes at 375F. This depends a lot on the moisture content, and the thickness of the crust.
NOTE - if the edges are getting much darker than the middle, make a "pie shield" by loosely covering the edge with aluminum foil. 3 pieces about 2-3 inches wide is usually sufficient. This slows down the cooking on the edge.
Remove from the oven, remove the parchment paper and weights, and then dock the base of the crust. This will let any steam escape so the crust doesn't bubble up.
Bake at 375F for around 15 more minutes, or until the top of the pie is golden brown.
