  PEP257 docstrings for file "./docs/__init__.py"
  Cover `./docs/__init__.py` file with docstrings and follow [PEP257](https://www.python.org/dev/peps/pep-0257/). We use [pydocstyle](https://pypi.org/project/pydocstyle/) for validation.
  
  Current validation log:
  
  ```
  ./docs/__init__.py:1 at module level:
          D104: Missing docstring in public package
  ```
  
  Subtask for #742 
  
  </issue>
