If you have a second bucket, then batch priming is the simpler solution. Make up a sugar syrup, bring to the boil and allow to cool. Put this in the empty bucket. Next, syphon the beer out of the fermentation bucket, onto the sugar syrup, avoiding splashes. The beer will mix with the syrup and the sugar should be distributed evenly, but you can always give it a gentle stir with a beer paddle, but don't splash it around or it will introduce unwanted oxygen.
It's best to have a bottling bucket fitted with a tap, and a bottling stick, but you can use a bottling stick with a piece of 5/16 syphon tubing and a racking cane, held in place with a clip.
Priming every bottle is the alternative, it takes longer and the beer can foam up when it hits the sugar, but many people do it.
