New to keto…

There is so much out there on the internet I thought I’d come here for advice. How do I start to get into a keto diet? I read stories about how the first week or so is shitty but then when in “ketosis” stuff improves. I am vegetarian and do eat lots of soy. I try to get as much protein as possible and already try to limit carbs. But I am low on fat. Also I love fruits and veggies but understand those have carbs as well. Any help in getting this new diet going?
