Ovulation help

Will someone please explain how to track for ovulation with the strips??? I’ve never done it, never had to, but my Doctor suggested i start doing so. I know little to nothing about doing so. How many tests/strips should i buy for a month? When do i test? How many times a day do i test? What day of my cycle should i start testing? Please help!! Most simplified , detailed explanation would be amazing😁👍🏻 thank you
