Syncing Audio

[katiemcc]

I'm new to editing and am a bit confused about syncing audio to video. If I was to record audio on an audio recorder connected to a shotgun microphone, would I have to sync it up to the video before I start editing or would I sync it on the timeline in my editing software?

if you look through mac break studios you tube videos,
