* Docstrings are required for classes, attributes, methods, and functions.
* Docstrings should utilize the [napolean style][docstrings] in order to make them read well, regardless of whether they are viewed through `help()` or on [Read the Docs][rtd].
* Please try to be consistent with the way existing docstrings are formatted. In particular, note the use of single vs. double backticks as follows:
* Double backticks
* Inline code
* Variables
* Types
* Decorators
* Single backticks
* Methods
