 # Releasing Jupyter Notebook
 
-## Automated releases
+## Using `jupyter_releaser`
 
-The recommended way to make a release is to use [`jupyter_releaser`](https://github.com/jupyter-server/jupyter_releaser#checklist-for-adoption).
+The recommended way to make a release is to use [`jupyter_releaser`](https://jupyter-releaser.readthedocs.io/en/latest/get_started/making_release_from_repo.html).
 
-We follow a similar bump strategy as in JupyterLab: https://github.com/jupyterlab/jupyterlab/blob/master/RELEASE.md#bump-version
+## Manual Release
 
-If you would still like to do the release manually instead, read below.
+To create a manual release, perform the following steps:
+
+### Set up
+
+```bash
+pip install hatch twine
+git pull origin $(git branch --show-current)
+git clean -dffx
+```
+
+### Update the version and apply the tag
+
+```bash
+echo "Enter new version"
+read new_version
+hatch version ${new_version}
+git tag -a ${new_version} -m "Release ${new_version}"
+```
+
+### Build the artifacts
+
+```bash
+rm -rf dist
+hatch build
+```
+
+### Publish the artifacts to pypi
+
+```bash
+twine check dist/*
+twine upload dist/*
+```
