The first thing you need to do is get all your supplies together.
Once we begin cutting into the roots air and light will be our
enemies- we will have to work fairly fast, and don't need to have
to go looking for the goldarned compost. If you are working
outdoors, a shady location is preferred. Mix your soil with
whatever ammendments you use, and get the pots or buckets mostly
filled up and watered well. Watering the newly mixed soil helps
it settle and reduces air pockets, and having water available is
handy if your roots dry out during the transplant (or you get mud
in your eye
)
