Here's a very basic primer.
As Dean said I use a 10 ft rod. It is a 5 wt G Loomis GLX Classic. It is not a true euro nymphing rod. It is too stiff but I use it for both dry and nymphing.
Here's one way to rig the flies. In a pure Euronymphing rig, they do not add split shot; they vary the weight of the flies. They also cannot use traditional "bobbers" as strike indicators. All indicators must be a part of the line or the leader. The fishing regulations in Europe is what developed this method of fishing.
However we can add weights and "bobber" so you can hybridize the rig above by adding split shot.
An entire book can be written on the special flies that are used. For a beginner, you can use bead head flies but the special flies are slim and weighted to sink very fast.
Rather than a high rod position, I use a lower parallel rod position. It is less tiring than holding the rod up and you have more control of the rift with the rod in a lower position. Also it is easier to set the hook with just a flip of the wrist. Take a look at the photo below. He is leading the flies just a bit and keeping the line off of the water.
There is a very slight bow in the line. Below is a bicolor strike indicator that is use to detect very subtle tales. You both "fee" and "see" the takes.
Indicator material that is placed into the leader. Usually it is used as the butt section OR a thinner version is placed just after the butt as part of the transition section.
This an "improved" version with high viz microdots to aid in detection.
Below is a graphic sequence of what you are going to try to do. You locate the likely position of fish. You position yourself so that you cast above the fish so that your flies will be at the level of the fish when the flies reaches the fish's lie. You know when the strike will likely occur.
This is not a random exercise but the result of many hours of experience. The "sixth sense" that you may think great nymphers have detecting strikes is a combination of experience and knowledge. They know their equipment, how to weight the flies, where to cast and when the strike will likely occur. You may not even see anything but they just know a fish has taken the fly.
Here is a frame taken from a video showing the bicolor indicator just above the water.
Here are more photos as examples. I want you to notice the different types of water from very fast in the first photo to slower in others and shallow to deep.
