The recommended INT tutorial

Is there an easier way to test or use an INT? I consulted past guides, encountered too many errors and spent three weeks trying to reproduce their results, but still ran into problems. For example, I have to change the ubuntu kernel, onos build error (npm install cost 1000+s), cannot pass the BPFcollector test, demo-bmv2 topo cannot ping…Although most of the above problems are solved, it is not a stable job (Good times and bad).I think this is outrageous
So I wonder if there is a more viable INT tutorial in the last two years that avoids the trivial operation process? Thank you so much (it took too much time,this is likely to discourage novices from trying INT )
