+    $ git push origin vX.Y.Z
+    ```
+
+### Manual QA in Jupyter
+
+We don't currently have automated tests for Jupyter, so we do this QA step manually.
+
+The `full_build` job in the `release_build` workflow in CircleCI produces a tarball of artifacts `output.tgz` 
+which you should download and decompress, which will give you a directory called `output`. The filenames within 
+will contain version numbers; make sure the version numbers are correct.
+
+Set up an environment with Jupyter, AnyWidget, and Pandas installed (`pip install jupyter anywidget pandas`). Then:
+
+- unzip downloaded `output.tgz`
+- `pip uninstall plotly`
+- `pip install path/to/output/dist/plotly-X.Y.Z-py3-none-any.whl`
+
+You'll want to check, in both JupyterLab (launch with `jupyter lab`) and Jupyter Notebook (launch with `jupyter notebook`), 
+that `go.Figure()` and `go.FigureWidget()` work as expected. 
 
-**Create a branch `git checkout -b release-X.Y.Z` *from the tip of `origin/main`*.**
+Notes:
+- **Start by creating a brand new notebook each time** so that there is no caching of previous results
+- **Do not run the Jupyter commands from the root `plotly.py/` directory on your machine** because Jupyter may be confused 
+by metadata from previous plotly.py builds
 
-Manually update the versions to `X.Y.Z` in the files specified below.
+Code for testing `go.Figure()`:
+```python
+import plotly
+import plotly.graph_objects as go
 
- - `pyproject.toml`
-   + update version
- - `CHANGELOG.md`
-   + update the release date
- - Commit your changes on the branch:
-   + `git commit -a -m "version changes for vX.Y.Z"`
- - Create a tag for Github release
-   + `git tag vX.Y.Z`
-   + `git push --atomic origin release-X.Y.Z vX.Y.Z`
- - Create a Github pull request from `release-X.Y.Z` to `main` and wait for CI to be green
+print(plotly.__version__)  # Make sure version is correct
+fig = go.Figure(data=go.Scatter(x=[1, 2, 3, 4], y=[1, 3, 2, 4]))
+fig.show()  # Figure should render in notebook
+```
 
-### Download and QA CI Artifacts
+Code for testing `go.FigureWidget()`:
+```python
+import plotly
+import plotly.graph_objects as go
 
-The `full_build` job in the `release_build` workflow in CircleCI produces a tarball of artifacts `output.tgz` which you should download and decompress, which will give you a directory called `output`. The filenames contained within will contain version numbers.
+print(plotly.__version__)  # Make sure version is correct
+fig = go.Figure(data=go.Scatter(x=[1, 2, 3, 4], y=[1, 3, 2, 4]))
+figure_widget = go.FigureWidget(fig)
+figure_widget  # Figure should render in notebook
+```
 
-To locally install the PyPI dist, make sure you have an environment with JupyterLab installed (maybe one created with `conda create -n condatest python=3.10 jupyter anywidget pandas`):
+Once these are verified working, you can move on to publishing the release.
 
-- `tar xzf output.tgz`
-- `pip uninstall plotly`
-- `conda uninstall plotly` (just in case!)
-- `pip install path/to/output/dist/plotly-X.Y.X-py3-none-any.whl`
+### Merge the release PR and make a GitHub release
