A comprehensive 5th Edition Dungeons & Dragons Framework for MapTool with character sheet and character creation tools, a compendium of items, features, spells and creatures and campaign management tools.
The framework can also be found at https://forums.rptools.net/viewtopic.php?f=85&t=28435
The .cmpgn file is all you need to run the framework. Olders versions are still available in case you are facing problems and want to downgrade.
This folder contains images and tokens that are not framework-specific, that you can use to create your own campaign.
You can check all the framework specific videos in the article about Video Tutorials, as well as generic MapTool tutorials.
Other than that, you can find help on various tools at the wiki.
