+## Check style of notebooks
+
+We can check the code style of our notebooks using [`ruff`][ruff] and
+[`nbqa`][nbqa]. Simply run the following command to check the style of the
+notebooks:
+
+```bash
+nbqa ruff notebooks
+```
+
+And run this to autoformat them:
+
+```bash
+nbqa ruff --fix notebooks
+```
+
+Alternatively, you can use the targets we have in the `Makefile`, like `make
+check` and `make format`. Read more information about the available targets
+by running `make help`.
