There are many good books on the subject; Moran/Barney's book, Jim Hrisoulas', lots of great information. Get em and read, read, read! Build 10 or 20 in your mind first and your hands, when finally dirty, will almost have 'already been there', almost. I read everything that I could find, everything! I was reading old manuscripts from the Berlin museum, online, of course.. All through my smithing career, I always had to read everything that I could find because, what if someone had some method whereby I might improve my work? And that is, after all, what that is about. Every knife, sword, axe is built technecally and creatively upon the previous. So much to learn, enjoy the ride. And the burns. Funny thing about the burns, I was real tempted to break out the tattoo equipment and tattoo a small 'legend' on the burns describing what I learned with/from each!
Wanna get started sooner? Get an acetylene or propane or even a Bernzomatic torch, some pliers, vice-grips, a small smooth faced hammer or two (like little sledge-hammers, not carpentry type), something to bang on (go to local machine shop and ask to buy a small block of steel (or some shape with a flat spot and perhaps some rounded) 15 or 20 pounds will do, and get some med to big nails/spikes at the hardware store. Find a place to put your anvil where it wont bounce and move (secure it). Hold nails in visegrips, heat to cherry red (and different colors) and whak away at the nail. Play, experiment, see what happens if... or if... Pound it when its cold. See the difference between that and cherry hot. Try it hotter, toward the orange and yellow range. Make a clothes hook. Play, play, play! Be creative. Hot metal is like clay in many ways, and moves like clay, you just use a hammer instead of your fingers. You have to master it before you can use your fingers and just squeeeeze that blade into shape!

Get simple books for some good habits. 'Forgery' is exercise for body and mind and spirit.
And with the nail and Bernzomatic set up, you have very little invested, can sample the techniques and stand to lose very little and can have some fun.
