+- Preamble content (between header and first section) is preserved
+- Multiple authors and descriptions are supported
+- Keywords and tags are automatically converted to Nostr t-tags

-   - d tag: publication identifier
-   - title tag: publication title
-   - a tags: references to 30041 content events (format: "30041:pubkey:d-tag")
-
-3. **Process**: When creating a 30040 event:
-   - Write your content with document title (= Title) and sections (== Section)
-   - The system will automatically split it into one 30040 index event and multiple 30041 content events
-   - The 30040 will have empty content and reference the 30041s via a tags`;
+1. **Content Structure**: Ensure your AsciiDoc starts with a document title (= Title)
+   - Add at least one section (== Section) for normal documents
+   - Use "index card" format for empty publications
+   - Include metadata in header lines or attributes, 
+     or add them manually to the tag list
+
+2. **Metadata**: Add relevant metadata to improve discoverability:
+   - Author: Use header line or :author: attribute
+   - Summary: Use :summary: or :description: attribute
+   - Keywords: Use :keywords: or :tags: attribute
+   - Version: Use revision line or :version: attribute
+   - Publication date: Use revision line or :published_on: attribute
+
+3. **Event Structure**: The system will automatically create:
+   - 30040 index event: Empty content with metadata and a-tags
+   - 30041 section events: Individual section content with section metadata
+
+4. **Common Issues**:
+   - Missing document title: Start with "= Your Title"
+   - No sections: Add "== Section Name" or use "index card" format
+   - Invalid metadata: Use proper AsciiDoc attribute syntax (:key: value)
+
+5. **Best Practices**:
+   - Include descriptive titles and summaries
+   - Use keywords for better searchability
+   - Add author information when relevant
+   - Consider using preamble content for introductions`;
