+Struct tags can be used to change the name of the item, or to ignore it.

 ### Golang map types
 
-Supported key types: `int`, `int8`, `int16`, `int32`, `int64`, `string`.  
+Supported key types: all integer types, `string`.  
 Supported value types: `string`, `[]byte`.
 
 ## Helper types
 
 Some actions are more complicated then necessary with the use of the default Go types and `MapOperations`.
 
-This is why goriak contains the types `goriak.Counter` and `goriak.Set`. Both of these types will help you performing actions such as incrementing a value, or adding/removing items.
