First step should always be a good reloading manual. The important thing about a reloading manual is it presents the steps to reloading in a logical and organized format.

There are probably over a dozen reputable publishers to choose from.
Pretty much all of the big manufacturers in the industry put one out and they are all good. Most experienced reloaders own several.
Once you have read through the manual twice, and have a basic understanding of the whole process start to finish, you can then take to youtube or come back to the forum to ask more specific questions about individual steps in the process, tools, components, etc.
Reloading is both an art and a science, and for many experienced reloaders also includes a healthy amount of ritual and superstition. Its a wonderful hobby in its own right.
It may seem daunting at first, but many reloaders are self taught with little to no supervision or training from experts. It can be very rewarding, and not only will it give you better ammo, will probably help you understand what goes on in a firearm when you pull the trigger and will make you a better shooter.
Don't be afraid to dive in, but a good manual, comprehensive but reading for the novice, will help you tackle it in a logical organized digestible fashion.
