+## Documentation from External Sources (Blog Posts, Announcements)
+
+When adapting content from external sources like blog posts into documentation:
+
+**DO:**
+- Work on one version, or topic at a time - never combine multiple versions in a single PR. Some blog posts or source material may include many versions or preview builds. The issue or task should specify which one to focus on.
+- Copy working code samples directly from source when available. Follow the rules under ["Code Snippets"](#code-snippets) above.
+- Create a checklist TODO for each section of the source document before writing.
+- Map each documentation section 1:1 to source content.
+- Explicitly state what is copied vs. generated in PR description.
+- Add disclaimers about AI usage when applicable.
+
+**DON'T:**
+- Invent or elaborate on features not explicitly mentioned in source.
+- Create placeholder sections without content.
+- Assume feature details or characteristics.
+- Combine information from multiple versions/sources.
+- Add examples without verifying they demonstrate the stated feature.
+
+**PR Description Must Include:**
+- Content source breakdown. In the description, list each section of the source document and indicate whether it was copied verbatim, adapted, or newly generated.
+- Note all generated sections requiring expert review.
+- Clear warnings about any uncertainties.
