If you are using a bottling bucket you must bottle immediately after siphoning your beer into there, it's not for aging of any type and it's different from a secondary.
I'm assuming you bought a kit with two buckets, and only one has a spigot. If so, you don't have a secondary so don't worry about it. Do your boil and pour your cooled wort into the non-spigot bucket along with the yeast. Let it sit around 3 weeks (take hydrometer readings). Once you're ready to bottle, add boiled priming sugar to bucket with spigot, siphon fermented beer into same bucket, then bottle immediately. Let beer carbonate in bottles at least 3 weeks at 70* before opening.
