+# schema
+
+this wiki has no imposed structure. pages are markdown files with optional YAML frontmatter.
+
+## frontmatter
+
+```yaml
+---
+title: Page Title
+visibility: public | private | unlisted
+tags: [topic1, topic2]
+---
+```
+
+## wikilinks
+
+link pages with `[[page-name]]` or `[[page-name|Display Text]]`. links resolve by filename — `[[linear-algebra]]` finds `wiki/courses/linear-algebra.md`.
