It is not complicated, the concept is simple, your skill level both as a roper and horse person is the key. Stockmanship is very important as well, the quieter you can handle your cattle to get them caught the better. Once you have a critter roped you have to get them to stand. Once standing walk around it 450 ° so that you end in the 3 o'clock position if there head is 12 o'clock. As you walk around be sure to lay your rope above the hocks, it will keep you from loosing the back legs. Now you give some slack and move your critter off easy and let it step over your rope with their front feet. Once the step over dally and tighten your rope, don't jerk them down, just ride off and you will draw their hind legs to their head and lie them down easily. If your critter takes off just keep your dally and set your horse they will pull their hind feet out from under themselves and it will fold their head around as it comes tight laying them over on their side. Ride up and dally short, holding the tale of your rope, instead of tying off, when you step off so you can loosen your dally in the event you need to let the critter go if it gets up on you. When you are ready to take your rope off slip some rope through your dallies and pull enough slack to get it off the head. It will be much easier to remove your rope if you can lie the critter down with your rope on the top side, if it ends on the bottom it can be difficult to pull slack through. Just a note, it is much easier to do the whole process if you use something besides rubber to wrap your horn, I use the strands out of a nylon rope, being able to quickly and easily slide rope is a big advantage. You can always tie one down if you are able, it is probably much safer and reduces the possibility of a wreck. It will take a few tries to get the hang of it, then it becomes simple on all sizes off cattle. It is probably easier on everything involved to doctor big cattle this way compared to heading and healing them. Sorry if there are a bunch off typos I am on my cell phone and don't use it very well.
