+The minium for docstrings is covering all parameters in an `Args:` block.
+
+```python
+Args:
+    width (int): The width of something
+    height (int): The height of something
+    title (str, optional): The title of something
+```
+
+* `Args:` should be used for all parameters
+* `Returns:` can be used if the return value needs additional explanation outside of
+   the current docstring. If the return type is already clear from type annotation it
+   can be omitted.
+* `Raises:` can be used if the function raises exceptions that need to be documented
+* `Yields:` can be used if the function is a generator and yields values
+* `Attributes:` we should try to avoid and instead document the attributes in the code
+* Types are visible in the api docs. It's not mandatory to include complex types in the
+  docstring, however, simpler typing is easy enough to include.
+* Using `optional` is a good way to indicate that a parameter is optional.
+* Properties and attribute docs don't need a return type when the return type
+  is already clear from type annotation.

+Attribute docstring in module or class:
+
+```py
+my_attribute_in_class_or_module: type = value
+"""This is a docstring for the attribute."""
