It would probably be a good idea to take the tutorial and watch a couple of videos, I'll post my "welcome blurb" below the line. For your specific questions: I am assuming since you said "Monster Manual" you are playing D&D5e. I'll proceed under that assumption. When creating a game, be sure to choose a character sheet. For 5e I would suggest the official sheet, it will make life easier for you. Choosing that sheet automatically connects your game to the resources of the SRD. This stands for System Reference Document, and is a subset of the rules that Wizards of the Coast makes available for free. There are quite a few monsters, base character classes, spells and such available for free, but it is a definitely a subset. The "i" icon on the sidebar to your right while in the game is your interface to the Compendium. From here you can drag monsters onto the map, spells onto character sheets and much more. This is freely available info and contains no WotC art or trademarked items (like Mind Flayers™). For many people this is enough, and might be good to test with while you are getting started. Feel free to ask any specific questions. Here's the welcome: First off: Welcome to Roll20! If you are looking for a quick hands-on introduction I would recommend taking the Tutorial . For a more in-depth guide, you can check out the excellent Tutorial Videos by Carlos Luna on Youtube, or my own video, Starting from Scratch . Additionally, starting your own test game to play with different features and controls is a great way of getting used to the software and layout!
