 - alignment of consecutive assignments by the equal sign;
 - pretty rich set of alignment settings in `File | Settings | Editor | Inlay Hints | Java | Java Code Aligner`.
 
+Please note, that fields alignment is performed only if its modifiers are placed
+in [the canonical order](https://docs.oracle.com/javase/specs/jls/se7/html/jls-8.html#jls-8.3.1).
+
 From the technical side, plugin works by adding invisible inlay hints (like the ones shown as parameter names for method
 calls), which can be made visible via `Enable debug mode` in settings above.
 
 Additionally, the plugin provides **folding of explicit types** to `var` and `final var` for local variable
 declarations, which can be enabled in `File | Settings | Editor | General | Code Folding | Java Code Aligner`.
