+A config object has a "plugins" key defined as an array${isArrayOfStrings ? " of strings" : ""}. It looks something like this:
+
+    {
+        "plugins": ${JSON.stringify(plugins)}
+    }
+
+Flat config requires "plugins" to be an object, like this:
+
+    {
+        plugins: {
+            ${isArrayOfStrings && plugins[0] ? plugins[0] : "namespace"}: pluginObject
+        }
+    }
+
+Please see the following page for information on how to convert your config object into the correct format:
+https://eslint.org/docs/latest/use/configure/migration-guide#import-plugins-and-custom-parsers
+
+If you're using a shareable config that you cannot rewrite in flat config format, then use the compatibility utility:
