+Synthetic Data Generator
+
+This extension is composed of a Python package named `jupyterlab-synthetic-data`
+for the server extension and a NPM package named `jupyterlab-synthetic-data`
+for the frontend extension.
+
+## Requirements
+
+- JupyterLab >= 3.0
+
+## Install
+
+To install the extension, execute:
+
+```bash
+pip install jupyterlab-synthetic-data
+```
+
+## Uninstall
+
+To remove the extension, execute:
+
+```bash
+pip uninstall jupyterlab-synthetic-data
+```
+
+## Troubleshoot
+
+If you are seeing the frontend extension, but it is not working, check
+that the server extension is enabled:
+
+```bash
+jupyter server extension list
+```
+
+If the server extension is installed and enabled, but you are not seeing
+the frontend extension, check the frontend extension is installed:
+
+```bash
+jupyter labextension list
+```
+
+## Contributing
+
+### Development install
+
+Note: You will need NodeJS to build the extension package.
+
+The `jlpm` command is JupyterLab's pinned version of
+[yarn](https://yarnpkg.com/) that is installed with JupyterLab. You may use
+`yarn` or `npm` in lieu of `jlpm` below.
+
+```bash
+# Clone the repo to your local environment
+# Change directory to the jupyterlab-synthetic-data directory
+# Install package in development mode
+pip install -e "."
+# Link your development version of the extension with JupyterLab
+jupyter labextension develop . --overwrite
+# Server extension must be manually installed in develop mode
+jupyter server extension enable jupyterlab-synthetic-data
+# Rebuild extension Typescript source after making changes
+jlpm build
+```
+
+You can watch the source directory and run JupyterLab at the same time in different terminals to watch for changes in the extension's source and automatically rebuild the extension.
+
+```bash
+# Watch the source directory in one terminal, automatically rebuilding when needed
+jlpm watch
+# Run JupyterLab in another terminal
+jupyter lab
+```
+
+With the watch command running, every saved change will immediately be built locally and available in your running JupyterLab. Refresh JupyterLab to load the change in your browser (you may need to wait several seconds for the extension to be rebuilt).
+
+By default, the `jlpm build` command generates the source maps for this extension to make it easier to debug using the browser dev tools. To also generate source maps for the JupyterLab core extensions, you can run the following command:
+
+```bash
+jupyter lab build --minimize=False
+```
+
+### Development uninstall
+
+```bash
+# Server extension must be manually disabled in develop mode
+jupyter server extension disable jupyterlab-synthetic-data
+pip uninstall jupyterlab-synthetic-data
+```
+
+In development mode, you will also need to remove the symlink created by `jupyter labextension develop`
+command. To find its location, you can run `jupyter labextension list` to figure out where the `labextensions`
+folder is located. Then you can remove the symlink named `jupyterlab-synthetic-data` within that folder.
+
+### Packaging the extension
+
+See [RELEASE](RELEASE.md)

+# Making a new release of jupyterlab-synthetic-data
+
+The extension can be published to `PyPI` and `npm` manually or using the [Jupyter Releaser](https://github.com/jupyter-server/jupyter_releaser).
+
+## Manual release
+
+### Python package
+
+This extension can be distributed as Python
+packages. All of the Python
+packaging instructions in the `pyproject.toml` file to wrap your extension in a
+Python package. Before generating a package, we first need to install `build`.
+
+```bash
+pip install build twine hatch
+```
+
+Bump the version using `hatch`. By default this will create a tag.
+See the docs on [hatch-nodejs-version](https://github.com/agoose77/hatch-nodejs-version#semver) for details.
+
+```bash
+hatch version <new-version>
+```
+
+To create a Python source package (`.tar.gz`) and the binary package (`.whl`) in the `dist/` directory, do:
+
+```bash
+python -m build
+```
+
+> `python setup.py sdist bdist_wheel` is deprecated and will not work for this package.
+
+Then to upload the package to PyPI, do:
+
+```bash
+twine upload dist/*
+```
+
+### NPM package
+
+To publish the frontend part of the extension as a NPM package, do:
+
+```bash
+npm login
+npm publish --access public
+```
+
+## Automated releases with the Jupyter Releaser
+
+The extension repository should already be compatible with the Jupyter Releaser.
+
+Check out the [workflow documentation](https://github.com/jupyter-server/jupyter_releaser#typical-workflow) for more information.
+
+Here is a summary of the steps to cut a new release:
+
+- Fork the [`jupyter-releaser` repo](https://github.com/jupyter-server/jupyter_releaser)
+- Add `ADMIN_GITHUB_TOKEN`, `PYPI_TOKEN` and `NPM_TOKEN` to the Github Secrets in the fork
+- Go to the Actions panel
+- Run the "Draft Changelog" workflow
+- Merge the Changelog PR
+- Run the "Draft Release" workflow
+- Run the "Publish Release" workflow
+
+## Publishing to `conda-forge`
+
+If the package is not on conda forge yet, check the documentation to learn how to add it: https://conda-forge.org/docs/maintainer/adding_pkgs.html
+
+Otherwise a bot should pick up the new version publish to PyPI, and open a new PR on the feedstock repository automatically.
