confused how I should start solids

So I'm starting solids next month and I'm still confused on how to start it. How did y'all start your LO on solids? Now I know that I should only do one food for a couple days because of allergies and what not. but what I mean is like do I feed him baby food once a day for a week or twice a day. I need help so I know before we start! Thanks!! :)
