 Simple types
 ^^^^^^^^^^^^
 Simple types include
- - int: numeric integers
- - float: numeric floating point values
- - bool: boolean values (True, False, On, Off etc)
- - str: any string
- - bytes: an immutable sequence of numbers in [0, 255]
- - pathlib.Path: filesystem paths as represented by python's standard library `pathlib`
- - Enums: User defined enums
+ - ``int``: numeric integers
+ - ``float``: numeric floating point values
+ - ``bool``: boolean values (True, False, On, Off etc)
+ - ``str``: any string
+ - ``bytes``: an immutable sequence of numbers in [0, 255]
+ - ``pathlib.Path``: filesystem paths as represented by python's standard library ``pathlib``
+ - ``Enums``: User defined enums
 
 The following class defines fields with all simple types:
