Step 1 Soil Preparation
Rake your lawn to remove any leaves or use a mulching lawn mower to mulch leaves until they are small enough to settle in amongst the blades of grass. It is important that the grass seed makes contact with the soil so dethatching your lawn with a dethatching rake or aerating your lawn is also good at this time. If those options are not available then it's a good idea to rake in a thin layer of enriched soil over your lawn. Don't put so much down that you kill your grass; less than a quarter of an inch is plenty. Scotts® Lawn Soil works well for this purpose.
