+# Importing Slides
+
+Split presentations into multiple files for reusability.
+
+## Basic Import
+
+```md
+# Title
+
+This is a normal page
+
+---
+src: ./pages/toc.md
+---
+
+<!-- Content here is ignored -->
+
+---
+
+# Page 4
+
+Another normal page
+```
+
+## Import Specific Slides
+
+Use hash to select slides:
+
+```md
+---
+src: ./another-presentation.md#2,5-7
+---
+```
+
+Imports slides 2, 5, 6, and 7.
+
+## Reuse Slides
+
+Import the same file multiple times:
+
+```md
+---
+src: ./pages/toc.md
+---
+
+<!-- later... -->
+
+---
+src: ./pages/toc.md
+---
+```
+
+## Frontmatter Priority
+
+Main entry frontmatter overrides imported file frontmatter for duplicate keys.
