 The JupyterLab-Blockly extension is ready to be used as a base for other projects: you can register new Blocks, Toolboxes and Generators. It is a great tool for fast prototyping.
 
 ## Creating a new JupyterLab extension
-You can easily create a new JupyterLab extension by using a `cookiecutter`. You can read more documentation about `cookiecutters` [here](https://cookiecutter.readthedocs.io/en/latest/), but the process is fairly straight-forward.

 ```

- the `cookiecutter` will ask for some basic information about your project. Once completed, it will create a directory containing several files, all forming the base of your project. You will mostly work in the `index.ts` file, located in the `src` folder.

+You will need to request the `jupyterlab-blockly` package as a dependency for your extension, in order to ensure it is installed and available to provide the token `IBlocklyRegistry`. To do this, you need to add the following line to your `pyproject.toml` file.
 
-```python
-// setup.py : 57
+```toml
+// pyproject.toml : 26
 
-setup_args = dict(
-  ...
-  install_requires=['jupyterlab-blockly>=0.3.2,<0.4']
-  ...
-)
+dependencies = [
+    "jupyterlab-blockly>=0.3.2,<0.4",
+    ... // add any additional dependencies needed for your extension
+]
 ```
 
-Moreover, as we are working with deduplication of dependencies and the extension you are creating requires a service identified by a token from `jupyterlab-blockly`, you need to add the following configuration to your `package.json` file.
-
+Additionally, you will need to add the webpack configuration for loading the `Blockly` source maps.
+
+You can do this, by creating the following `webpack.config.js` file inside your root directory:
+
+```js
+// @ts-check
+
+module.exports = /** @type { import('webpack').Configuration } */ ({
+  devtool: 'source-map',
+  module: {
+    rules: [
+      // Load Blockly source maps.
+      {
+        test: /(blockly\/.*\.js)$/,
+        use: [require.resolve('source-map-loader')],
+        enforce: 'pre'
+      }
+    ].filter(Boolean)
+  },
+  // https://github.com/google/blockly-samples/blob/9974e85becaa8ad17e35b588b95391c85865dafd/plugins/dev-scripts/config/webpack.config.js#L118-L120
+  ignoreWarnings: [/Failed to parse source map/]
+});
 ```
-// package.json : 88-101
 
+and by connecting the `webpack` config to your `jupyterlab` intstance, by adding the following line inside your `package.json`: 
+
+```json
 "jupyterlab": {
-  "sharedPackages": {
-     "jupyterlab-blockly": {
-       "bundled": false,
-       "singleton": true
-     },
-     "blockly": {
-       "bundled": false,
-       "singleton": true
-     }
-   }
- }
-```
-This ensures your extension will get the exact same token the provider is using to identify the service and exclude it from its bundle as the provider will give a copy of the token. You can read more about deduplication of dependencies [here](https://jupyterlab.readthedocs.io/en/stable/extension/extension_dev.html#deduplication-of-dependencies), in the official *Extension Developer Guide for JupyterLab*.
