-## Updating Dependencies
 
-To update `@wordpress` dependencies, simply execute:
+### The `entries` directory and entry points
+All directories created in the `entries` directory can serve as entry points and will be compiled with [@wordpress/scripts](https://github.com/WordPress/gutenberg/blob/trunk/packages/scripts/README.md#scripts) into the `build` directory with an accompanied `index.asset.php` asset map.
+
+#### Enqueuing Entry Points
+
+You can also include an `index.php` file in the entry point directory for enqueueing or registering a script. This file will then be moved to the build directory and will be auto-loaded with the `load_scripts()` function in the `functions.php` file. Alternatively, if a script is to be enqueued elsewhere there are helper functions in the `src/assets.php` file for getting the assets.
+
+### Scaffold a block with `create-block`
+
+Use the `create-block` command to create custom blocks with [`@wordpress/create-block`](https://developer.wordpress.org/block-editor/reference-guides/packages/packages-create-block/) and follow the prompts to generate all the block assets in the `blocks/` directory. 
+Block registration, script creation, etc will be scaffolded from the `bin/create-block/templates/block/` templates. Run `npm run build` to compile and build the custom block. Blocks are enqueued using the `load_scripts()` function in `src/assets.php`.
+
+### Updating WP Dependencies
+
+Updates the [WordPress dependency packages](https://developer.wordpress.org/block-editor/reference-guides/packages/packages-scripts/#packages-update) used in the project to their latest version.
+
+To update `@wordpress` dependencies to their latest version use the packages-update command:
+
+```sh
+npm run packages-update
+```
+
+This script provides the following custom options:
+
+-   `--dist-tag` – allows specifying a custom dist-tag when updating npm packages. Defaults to `latest`. This is especially useful when using [`@wordpress/dependency-extraction-webpack-plugin`](https://www.npmjs.com/package/@wordpress/dependency-extraction-webpack-plugin). It lets installing the npm dependencies at versions used by the given WordPress major version for local testing, etc. Example:
 
 ```sh
-npm run update-dependencies WPVERSION
+npm run packages-update --dist-tag=wp-WPVERSION`
 ```
 
 Where `WPVERSION` is the version of WordPress you are targeting. The version
-must include both the major and patch version (e.g., `5.9.3`). For example:
+must include both the major and minor version (e.g., `6.1`). For example:
 
 ```sh
-npm run update-dependencies 5.9.3
