 CAUTION: Due to the flat representation structure, Map keys need to be simple types, such as ``String`` or ``Number``.
 
 Mapping behavior can be customized by registering the corresponding `Converter` in `RedisCustomConversions`.
-Those converters can take care of converting from and to a single `byte[]` as well as `Map<String,byte[]>`.
+Those converters can take care of converting from and to a single `byte[]` as well as `Map<String, byte[]>`.
 The first one is suitable for (for example) converting a complex type to (for example) a binary JSON representation that still uses the default mappings hash structure.
 The second option offers full control over the resulting hash.
