Re connecting to hotspot, this is basically just like connecting to your WiFi router.

When you get a hangup, search the forum and if you can't find what you need doing that then just ask. Try to be specific since general questions can be difficult to tackle !
My tip, don't try to accomplish everything at once. You'll get overwhelmed. The easiest way to go about it is a single profile and then as you go, you'll see if you want to add profiles for isolation. In terms of the inevitable "Aurora vs Google" question, a burner Google Play account you control is the ideal solution. Even using a personal Play account gets benefits from GOS & non-priviliged Google services. It's one of the perks of GOS, you can use it however you want and know you're miles ahead of stock Android/competitors.
Lastly, make sure to verify your install and set Auditor. Some users seem to skip that step and wonder about it down the road... It's all at the bottom of the install guide.
Welcome and enjoy your GOS experience
