Hey there mate.
For starters, i highly reccomend you to start using a Gainer, they are really good. Mutant mass or Super mass are two good ones.
Other than that its not so much about how MUCH you lift, considering you need to get the exercises right. Considering ur height you should start with really, really light weights for about two months before attempting anything heavier (Ofcourse you adjust this on the go).
Im ur height, and i made the mistake to lift too heavy. My shoulder went caput and had to train it up for two months. Also, remember to stretch out after every session.
Try to eat four times a day, at roughly the same times. Coupple that with 3 gainer shakes-per day and you will notice a weight gain. Also, eat somewhat proper.
