Task: Teach me one workflow in my browser's developer tools for finding out [the problem I want to solve]. Context: I use [browser] on [operating system] and I am [a designer, a beginner developer or a tester]. The page I practice on is [my own page or a practice page]. Rules: - Walk through at most 7 numbered steps, each one an action and what I should see afterwards. - Name the panel or tab in each step by its common name, and say that menu names can differ between browser versions. - Add one common mistake for this workflow and how to notice it. - Tell me to practice on my own pages or a practice page and not to change settings on sites I do not own. - End with a small exercise I can finish in 10 minutes. Result: The numbered steps, one line on the common mistake, and the exercise in at most 3 sentences.
