Tutorial for LoL

Can you make or at least copy someones guide how to play LoL and post it on client, basic stuff like, that objectives are worth more than kills not worth more gold than kill but worth more overall, when to pull back, when not to overstay, going for baron when they shouldn´t, adc going alone with no vision etc. I´m seriously tierd of pinging and typing like idiot every game when and what someone should do, than one second I don´t ping I see tower diving that could take 2 towers instead of that one kill she got and died, I swear the amount of people I started seeing in ranked that have no clue how to play the game is astonishing and in low/mid plat at that, I don´t care if they feed sure there will be games where I can´t do jack shit because is 10 2 or when I feed, it´s ok I win some I lose some, but I´m sick of getting huge lead than losing it because some idiot tought it was great idea to stay when he shouldn´t. Oh and give me some tips how you win with players like this? Do you just ignore them or do you try to help them? PS: Thank you for all the time you spent reading this rant and sorry if I posted it in wrong board type.
