+# JC2-MP Wiki
+
+This is the JC2-MP wiki, recovered from a 2014 backup and deployed to GitHub Pages.
+
+## About
+
+After recovering the wiki content from a 2014 wikitext dump, we built a custom Rust-based static site generator to render it. The SSG parses MediaWiki markup, processes templates, and generates a fully static website that mirrors the original wiki, without any of the overhead of running MediaWiki itself.
+
+Some effort will be made to salvage additional content from Internet Archive as time and effort permit.
+
+## Building the Site
+
+```bash
+cargo run
+```
+
+This generates the static site in the `output/` directory. This is run by the CI, which will then automatically deploy to GitHub Pages.
