 comment brings nothing more than the type hint and variable name already do,
 it SHOULD be removed. Descriptions are OPTIONAL if you want to document a type.
 
+If you want to use pseudo-types, generics, array shapes or templates for
+static-analysis, prefer the usage of `@phpstan-` annotations over classic
+annotations to keep IDE support, and over `@psalm-` annotations for consistency.
+Keep standard annotations if necessary.
