I've made a D&D 5e campaign that has gone over well DMing for a couple different groups of players.
I'd like to compile it into a format that is digitally distributable and easier to navigate than a traditional physical book or pdf module.
My first thoughts on doing this is to use Twine or a similar program and organize the information by chapters or scenes, then having an appendix that will link to given information about an in-game location, item, etc.

I guess my thoughts could be summed up in a few questions:

• Are there adventure templates or programs Google didn't tell me about that make the process of putting this information together efficient and patron-GM friendly?
• Even better, have you made a distributable adventure module, and if so, how did you go about making it accessible to the every-day GM? This question has less to do with marketability and more to do with functionality/user-friendliness on the GM-side.
• And I guess that brings up another good question: do you think that itch.io is a good place to distribute your role-playing adventure module for an existing game ruleset like D&D?

Looking forward to your ideas, experiences, and input :)
