 ## Structures
 
 Inputs and outputs of API calls are represented as plain Python classes derived from
-`Structure` class. All structures have a constructor with a single parameter that
-creates a structure object from a JSON object represented as a `dict` (as returned
-from `json.load()`). The constructor automatically converts field names from camel
-case to snake case (if needed) and creates nested structures in accordance with fields'
-type specifications.

-The constructor is designed to be used internally, but you can also use it to
-initialize a structure. These code snippets are equivalent:

 `json()` method converts the structure back to a `dict` representing a JSON structure,
 converting all field names to camel case.
