-    EditorConfig plugins can be developed by using one of the EditorConfig core libraries.
+    EditorConfig editor plugins must follow the <a href="https://spec.editorconfig.org">specifications</a>. They can be developed with the help from one of the EditorConfig core libraries.
     The EditorConfig core libraries accept as input the file being edited, find and parse relevant <code>.editorconfig</code> files, and pass back the properties that should be used.
     Please ignore any unrecognized properties and property values in your editor plugin for future compatibility, since new properties and permitted values will be added in the future.
