Gutters need to slope toward the downspout. About 1/4 inch for every 10 feet. Too much slope and your gutters look drunk; too little and water sits there, mocking you.
Snap a chalk line along the fascia board—the board right under the roof edge. That line is your guide. Check it with a level. If it looks like a funhouse mirror, adjust your brackets before you screw anything permanent.
Here’s the rhetorical question of the day: do you want to redo this next weekend? No? Then double-check the slope now. Future you will send a thank-you card.

Step 3: Attach the Brackets (The Real Work)
Brackets are those little metal claws that hold the gutter to the house. Screw them into the fascia board along your chalk line. Space them every 24 to 30 inches—closer if you live somewhere with aggressive weather (hello, hurricane season).
Don’t over-tighten the screws. You’re not trying to reconcile the board to the earth’s core. Just snug them so they hold without stripping. Stripped screws are the soul-sucking gremlins of home improvement.
If you’re working with a hidden bracket system (fancy!), slide the bracket into the back of the gutter. If you’re using standard brackets, you’ll attach them after the gutter is in place. Read the instructions—I can’t see your brand from here.
