When first starting out, use a shovel to dig a trench about a foot wide and eight inches deep. Put the soil from the trench in a wheelbarrow. Next spread some manure or compost in the trench and cover it with the soil from the next trench. Repeat this until you've reached the last trench, then fill it with the soil in the wheelbarrow. Afterward, add manure, compost, peat, or any other nutrient-rich materials and work it into the soil with a hoe.
