+Unfortunately, JSON files do not support comments, but you can add extra entries to the JSON to use as comments. You will see an error in about:policies, but the policies will still work properly. For example:
+
+```
+{
+ "policies": {
+ "Authentication": {
+ "SPNEGO": ["mydomain.com", "https://myotherdomain.com"]
+ }
+ "Authentication_Comment": "These domains are required for us"
+ }
+}
+```
