I would start with good reliable books, like Minhaj al- Muslim, and authentic websites, like islamqa.com or islamweb.net, by reputable scholars.
Six etiquettes of learning
lbn Qayyim Al-Jawziyyah
said: "There are six stages to knowledge:
Firstly: Asking questions in a good manner.
Secondly: Remaining quiet and listening attentively.
Thirdly: Understanding well.
Fourthly: Memorising.
Fifthly Teaching.
Sixthly- and it is its fruit: Acting upon the knowledge and keeping to its limits."
