-If you do wish to use *Black* alongside `isort`, you can pass the following
-command-line arguments to ensure compatible behaviour:
-```
-$ isort --multi-line=3 --trailing-comma --force-grid-wrap=0 --line-width=88 [ file.py ]

-Or use the equivalent directives in your isort config:
```

multi_line_output=3

line_length=88

### Line length
You probably noticed the peculiar default line length. *Black* defaults
It will also insert proper spacing before and after function definitions.
It's one line before and after inner functions and two lines before and
-after module-level functions. *Black* will not put empty lines between
-function/class definitions and standalone comments that immediately precede
-the given function/class.
+after module-level functions and classes. *Black* will not put empty
+lines between function/class definitions and standalone comments that
+immediately precede the given function/class.
+
+*Black* will enforce single empty lines between a class-level docstring
+and the first following field or method. This conforms to
+[PEP 257](https://www.python.org/dev/peps/pep-0257/#multi-line-docstrings).
+
+*Black* won't insert empty lines after function docstrings unless that
+empty line is required due to an inner function starting immediately
+after.
