+Limit further_reading resources to 4-6 essential links. Prioritize:
+- Direct relevance to the topic
+- Arm-specific Learning Paths over generic external resources  
+- Foundation knowledge for target audience
+- Required tools (install guides)
+- Logical progression from basic to advanced

+Avoid overwhelming readers with too many links, which can cause them to leave the platform.

 ### Internal links
 
-Use a relative path format for internal links that are on learn.arm.com. 
-For example, use: descriptive link text pointing to a relative path like learning-paths/category/path-name/
+Use the full path format for internal links: `/learning-paths/category/path-name/` (e.g., `/learning-paths/cross-platform/docker/`). Do NOT use relative paths like `../path-name/`.
 
 Examples:
-- learning-paths/servers-and-cloud-computing/csp/ (Arm-based instance)
-- learning-paths/cross-platform/docker/ (Docker learning path)

 ### External links
 
 Use the full URL for external links that are not on learn.arm.com, these open in a new tab.

+### Link Verification Process
 
+When creating Learning Path content:
+- Verify internal links exist before adding them
+- Use semantic search or website browsing to confirm Learning Path availability
+- Prefer verified external authoritative sources over speculative internal links
+- Test link formats against existing Learning Path examples
+- Never assume Learning Paths exist without verification
