Hello @rene.anthony and welcome to OGS 
regarding the tutorial it has been brought up before and there is more discussion here if you were interested and/or wanted to give more pointers Does the learn to play go section need more explanations? For what it’s worth, I am trying/hoping to improve the section, but keep getting interrupted by real life duties. But it should get better soon hopefully - fingers crossed.
If you would not mind a bit of self advertisement - if you are looking for a more detailed introduction to the game together with several other OGS users we have built this tutorial - which is more “explanation” focused to provide a counterpart to the OGS “quick” one.
