+A JupyterLab extension.
+
+## Requirements
+
+- JupyterLab >= 3.0
+
+## Install
+
+To install the extension, execute:
+
+```bash
+pip install jupyterlab_minio_browser 
+```
+
+## Uninstall
+
+To remove the extension, execute:
+
+```bash
+pip uninstall jupyterlab_minio_browser 
+```
+
+## 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_minio_browser  directory
+# Install package in development mode
+pip install -e .
+# Link your development version of the extension with JupyterLab
+jupyter labextension develop . --overwrite
+# 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
+pip uninstall jupyterlab_minio_browser 
+```
+
+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-minio-browser ` within that folder.
+
+### Testing the extension
+
+#### Frontend tests
+
+This extension is using [Jest](https://jestjs.io/) for JavaScript code testing.
+
+To execute them, execute:
+
+```sh
+jlpm
+jlpm test
+```
+
+#### Integration tests
+
+This extension uses [Playwright](https://playwright.dev/docs/intro/) for the integration tests (aka user level tests).
+More precisely, the JupyterLab helper [Galata](https://github.com/jupyterlab/jupyterlab/tree/master/galata) is used to handle testing the extension in JupyterLab.
+
+More information are provided within the [ui-tests](./ui-tests/README.md) README.
+
+### Packaging the extension
+
+See [RELEASE](RELEASE.md)

RELEASE.md

+# Making a new release of jupyterlab_minio_browser 
+
+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
+```
+
+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.
