First step is to thoroughly understand the building process and sequence of construction as well as all the materials, fasteners, tools, etc. Then for building, start small with a chicken coop or shed with relatively low risk if the build goes south. Going from zero to house without serious supervision from experience builders is a recipe for a failed structure.

Check out Larry Haun's books as well as the Essential Craftsman Youtube channel where he films an entire house build. Also the Build Channel with Matt Risinger is great for more advance topics.
