I don't have one at hand currently. Any part you're stuck on in particular? I'll gladly give hints, and maybe make stuff more intuitive in future updates. There's a thread on animeotk where people share hints as well
Did you do the first quest that prompts when you exit the apartment? The one to find Adik and Irina. There's only 1 sidequest (in the little playground) available before the girls join your party. You can check your quest log in the menu if you need a reminder
