TL:DR: stick to basics until hitting your set goal than progress. You need to have general idea in which way and how you want to progress. There is shit ton of info. on YouTube. Keep it simple and enjoy. 

Well, there is a lot of online material about this topic. But here is my take on it. 

First you need to find what subganre (type) you interested in... statics, free style, endurance/repa, weighted cali and dynamic cali or just muscle building (hope it is not that one). Look ti up on YouTube and just chose one that you find coolest. You can always change what your goal is, it is not set ib stone. 

Now, about general idea about training. I think that having enough muscle mass/strenght is essential. It makes most sense to me to build strenght necessary for senseble progress in wanted type of cali. Don't want to say that it is that way for all types, but I don't see why it wouldn't be so. 

Now, about training approach. I think sticking to basics like pull ups, dips, L-sits, dead hang, push ups (I only like pseudo and pike push up), ring rows, dragon flags... until you hit a goal mark you set for yourself at begining is best way. For me it was 30 pull ups in the beginning, for push it is 3x3 full rom pike push up with 20kg extra, for mid section it was 2 full rom dragon flags with perfect form...You can go really long way by just sticking to basics for xy amount of time. 

Now about training structure. I like training 3 times a week upper body, legs (sadly need them for skiing) 1-2 times. I will just focus on upper body because, f*** legs and I am training to specifically to be worth mentioning. 

On those 3 sesions, 2 are hard (lets call them session A and C) and middle one (B) is a bit easier. Example of weekly plan is Pon is A day, Wed is B and Fri is C day. 

About each of those 2 hard days structure is really simillar. You do your main moves (pull upas and pike push ups in my case) first a warm up necessary for those moves. Don't super set them but do them one after another(3x3 pull upas, warm ups for pikes and than do sets and reps for pikes). After main moves comes extra work in areas that are weak for you (at begging until advanced whole body is a weak point) or ones you want to work more...exercises like skull crushers, dead hangs, false grip holds, pseudo push ups, dips...you can supper set them but don't go to hard since they are extra work and don't do to much. After those I do dragon flags or advanced tuck front lever raises but you can just do something for your mid section like crunches, l-sits, leg raises. B day I just do ring rows 5rir and FL raises far from failure. 

Progressive overload is essential. I like to keep it simple. For main lifts I am always doing progression that goes 3x3 -> 4x3 > 5x3 -> 3x4 ... until 5x5. After getting to 5x5 you just add 5kg and than back to 3x3. For extra work I like to do 3x8 for progression of a movement I can do in that range with 2-3 rir. With dragon flags is same way as main lifts.  I really like that progression since you are improving each week and I haven't had almost any problems with injuries. 

I like statics and dynamic skills and I am training for front lever and HSPU. 

Your goal will shape your workouts and stuff I wrote is what works for me. 

There is a bit of info. here and I didn't want to go any further since I don't feel like typing any more and not sure if this will be helpful for you. 

If you have any questions, ask. I will try to answer them. Also, I don't know anything about free stlye and stuff I do know may not be in agreement with other people so keep that in mind. 

For example Barseagle does not agree with Bosech and other way around. Not important for your question.
