 .SYNOPSIS
-    Compiles changelog entries from YAML files into CHANGELOG.md.
+    Compiles changelog entries from YAML files into CHANGELOG.md with contributor attribution.
 
 .DESCRIPTION
     This script reads all YAML files from the changelog-entries directory,
     validates them against the schema, groups them by section and subsection,
     and inserts the compiled entries into CHANGELOG.md under the specified version section.
     
+    The script automatically extracts contributor information from git commit history
+    based on PR numbers. For each change, it attributes the PR to the contributor and
+    identifies first-time contributors to add them to a "New Contributors" section.
+    
+    Contributor attribution:
+    - Changes are attributed inline as: "description by @username in [[#123](link)]"
+    - First-time contributors are listed in a "New Contributors" section
+    - Bot accounts and Microsoft employees are excluded from attribution
+    - External contributors are identified from GitHub noreply emails or non-microsoft.com emails
+    
     If no version is specified, entries are added to the "Unreleased" section at the top.
     If there is no "Unreleased" section and no version is specified, a new "Unreleased" 
     section is created using the next semantic version number.
