+$tip.TipText = @'
+The Group-Object cmdlet groups objects by the value of a specified property, similar to SQL's GROUP BY clause. Each group has a Count property showing how many objects share the same value, and a Group property containing the matching objects.
+
+This is great for quickly summarizing data: counting files by extension, spotting duplicate values, grouping processes by status, and more. Use -NoElement when you only need the counts and don't need the grouped objects themselves (saves memory). Combine with Sort-Object to rank results.

+$tip.Example = @'
+# Count files in a directory by extension.
+Get-ChildItem -Path 'C:\Temp' | Group-Object -Property Extension
+
+# Show only the count and name (no grouped objects) for a lighter result.
+Get-ChildItem -Path 'C:\Temp' | Group-Object -Property Extension -NoElement | Sort-Object Count -Descending
+
+# Find duplicate values in an array.
+$fruits = 'apple','banana','apple','cherry','banana','apple'
+$fruits | Group-Object | Where-Object Count -gt 1
+
+# Group running processes by their status, then inspect one group.
+$groups = Get-Process | Group-Object -Property Responding
+$notResponding = ($groups | Where-Object Name -eq 'False').Group
+
+# Group services by start type and show a summary.
+Get-Service | Group-Object StartType -NoElement | Sort-Object Count -Descending
