Completely new to planting veg…

Hello all, I’ve been wanting to grow my own veg for a while, but literally haven’t a clue where to start. Do I just put seeds straight into soil/compost? I will be potting & using raised beds as my garden constantly sprouts nettles, even when I think their gone (turned the whole garden over at one point to pull the roots out) out comes another lol. But back to my question any tips or advice on where to start? Please help a girl out x
