“Fishing smarter for trout” By Tony Bishop is a great book for beginners
Has lots of info on where to look for fish and methods and such.
He also has a website you can find with google easy enough.
Try trademe for the book i got one for a friend for less than $10.
Starting fly fishing practice on a lawn with a bit of wool on the end of your leader and get the process right before you tie on a fly failure to do so will end up with a lot of $2 casts ( your fly cracking off the leader when you don’t wait for the loop to straighten before starting you forward stroke)
