+Quartz supports [Obsidian Bases](https://help.obsidian.md/bases), which allow you to create dynamic, database-like views of your notes. See the [official Obsidian documentation](https://help.obsidian.md/bases/syntax) for the full syntax reference.
+
+## Quick Example
+
+Create a `.base` file in your content folder:
+
+```yaml
+filters:
+  and:
+    - file.hasTag("task")
+
+views:
+  - type: table
+    name: "Task List"
+    order:
+      - file.name
+      - status
+      - due_date
+```
+
+Each view gets its own page at `<base-name>/<view-name>`.
+
+## Wikilinks
+
+Link to base views using the standard [[Navigation.base#Plugins|wikilink]] syntax:
+
+```markdown
+[[my-base.base#Task List]]
+```
+
+This resolves to `my-base/Task-List`.
+
+## Configuration
+
+This functionality is provided by the [[ObsidianBases]] transformer plugin (which parses `.base` files) and the [[BasePage]] emitter plugin (which generates the pages).
