+## enforce-map-style
+
+_Description_: This rule enforces consistent usage of `make(map[type]type)` or `map[type]type{}` for map initialization. It does not affect `make(map[type]type, size)` constructions.
+
+_Configuration_: (string) Specifies the enforced style for map initialization. The options are:
+- "any": No enforcement (default).
+- "make": Enforces the usage of `make(map[type]type)`.
+- "literal": Enforces the usage of `map[type]type{}`.
+
+Example:
+
+```toml
+[rule.enforce-map-style]
+  arguments = ["make"]
+```

 ## error-naming
 
 _Description_: By convention, for the sake of readability, variables of type `error` must be named with the prefix `err`.
