 ## New in v1.28
 
+# Experimental Feature: 'sourceEdit'
+New feature that adds an 'edit' subcommand to the 'source' command. This can be used to set an explicit source to be implicit and vice-versa. For example, with this feature you can make the 'winget-font' source an implicit source instead of explicit source.
+
+To enable this feature, add the 'sourceEdit' experimental feature to your settings.
+```
+"experimentalFeatures": {
+    "sourceEdit": true
+},
+```
+To use the feature, try `winget source edit winget-font` to set the Explicit state to the default.
