x2. Youtube is great.
There are a lot of articles on this online that are worth looking into.
A few basics:
First thing to learn is what drag is. I won't try to explain because there are better sources of info than me. Learn how to "mend" a line. That's how you fix it. I will say this, if you cast a fly across a stream and let it drift, your line will belly out in the current and drag the fly across/through the water. This looks unnatural as most things are drifting unimpeded and this also makes the fly put a little disturbance in the water as it cuts across current. Fish can detect this and it looks unnatural.
The cure is learning to "mend" the line. Mending is an essential skill in flyfishing. Essentially you are repositioning the line upstream so it doesn't belly out during the drift. I find myself doing this: cast out and then give the line a little flip to get the slack positioned upstream of the fly. I repeat it a few times in the drift since the line inevitably catches up. If you are seeing a big belly or arc in your line, you've probably got drag. You want your line to look zig-zagged as it drifts so the fly is going downstream naturally.
What will happen is that the current pulling on your fly line will take it downstream faster the than the fly. A big D-shaped, arcing belly will form in the line. (I tried to draw but it didn't work). Don't let that belly form!
Get that upstream. If you are not fishing with an indicator, let the fly swing down below you and let it hang there for a bit. It looks like some critter suspended or rising in the water column and that often gets a fish to hit (normally a hard one).
