+# Quickstart: Relational Document System
+
+This guide provides a quick overview of how to use the relational document system.
+
+## 1. Create a Document
+
+Create a new markdown file (e.g., `people/john-doe.md`) with YAML frontmatter:
+
+```markdown
+---
+type: person
+name: John Doe
+email: john.doe@example.com
+---
+
+# John Doe
+
+This is a document about John Doe.
+```
+
+## 2. Create a Query
+
+Create a new markdown file to define a query (e.g., `views/all-people.md`):
+
+````markdown
+```notex
+query: person
+sort_by: name
+```
+````
+
+## 3. View the Results
+
+When you open the `views/all-people.md` file, the plugin will execute the query and display the results in a virtual buffer:
+
+```
+| name     | email                  |
+|----------|------------------------|
+| John Doe | john.doe@example.com   |
+| ...      | ...                    |
+```
+
+## 4. Linking Documents
+
+You can link to other documents using the standard markdown syntax:
+
+```markdown
+See also: [John Doe](people/john-doe.md)
+```
