-### Configuration
+### Profile
+
+Since version 5.0.0, isort supports
+[profiles](https://pycqa.github.io/isort/docs/configuration/profiles/) to allow easy
+interoperability with common code styles. You can set the black profile in any of the
+[config files](https://pycqa.github.io/isort/docs/configuration/config_files/) supported
+by isort. Below, an example for `pyproject.toml`:
+
+```toml
+[tool.isort]
+profile = "black"
+```
+
+### Custom Configuration
+
+If you're using an isort version that is older than 5.0.0 or you have some custom
+configuration for _Black_, you can tweak your isort configuration to make it compatible
+with _Black_. Below, an example for `.isort.cfg`:

 
 ```

 include_trailing_comma = True
 force_grid_wrap = 0
 use_parentheses = True
