Grimoire

Grimoire is a Jekyll quasi-wiki theme built specifically for RPG-oriented worldbuilding, turning Markdown content into a static lore site without a database or server-side application.

What is Grimoire?

Grimoire is an open-source Jekyll theme that functions as a quasi-wiki for tabletop role-playing game worldbuilding. It takes Markdown files as input and produces a static wiki website, hosted on any Jekyll-compatible platform. The project is maintained by Nereare and distributed as the Ruby gem nereare_grimoire. It is released under the Hippocratic License and uses Semantic Versioning for releases, with a CHANGELOG documenting history. The documentation at nereare.github.io/Grimoire provides installation and running instructions. The repository includes a Contributor Code of Conduct (Contributor Covenant v1.4) and Contributing Guidelines.
