-# Magento 2 PWA
+# PWA Metapackage for Magento Open Source Extensions
 
-Welcome to the Magento 2 PWA Open Source Extensions
+Welcome to PWA metapackage for Magento Open Source extensions.
+As a metapackage for Magento Open Source, this repo enables PWA extension developers to add any additional Magento Open Source features they need to support their PWA modules.
 
-## Modules
-### [Magento_ContactGraphQlPwa (magento/module-contact-graph-ql-pwa)](ContactGraphQlPwa/README.md)
-Provides GraphQl functionality for the contact-us form.
+## Current Modules
 
-### [Magento_NewsletterGraphQlPwa (magento/module-newsletter-graph-ql-pwa)](NewsletterGraphQlPwa/README.md)
-Provides additional GraphQl functionality for the newsletter subscriptions in PWA.

+## Development setup
+
+To setup and develop your PWA extension modules locally, use the following instructions:
+
+### Installation as a git-based composer package
+
+1. Clone and/or navigate to your [`magento2` git repository](https://github.com/magento/magento2) and check out the latest develop branch, e.g. `2.4-develop`. You may also check out and use any `2.4` release tags.
+
+    ```bash
+    git clone [email protected]:magento/magento2.git
+    cd magento2
+    ```
+
+1. Create an `ext` directory within the root of your `magento2` project:
+
+    ```bash
+    mkdir ext
+    ```
+
+1. Clone the `magento2-pwa` repository into your vendor directory name:
+
+    ```bash
+    git clone [email protected]:magento-commerce/magento2-pwa.git ext/magento/magento2-pwa
+    ```
+
+1. Update the `magento2/composer.json` settings to create a better development workflow for your extension modules:
+
+    -  Update the `minimum-stability` for packages to `dev`. This allows for the installation of development modules:
+
+        ```bash
+        composer config minimum-stability dev
+        ```
+
+    -  To work with `stable` packages, ensure that the `prefer-stable` property is `true`. This property should already be included in the `composer.json` file, right above the `minimum-stability` setting.
+
+    -  Configure `composer` to find new extension modules. The following command configures `composer` to treat any extension code inside the `ext` directory as a package and creates a symlink to the `vendor` directory:
+
+        ```bash
+        composer config repositories.ext path "./ext/*/*/*"
+        ```
+
+1. Install the `pwa` metapackage:
+
+    ```bash
+    composer require magento/pwa
+    ```
+
+At this point, you should see symlinks for all the `pwa` modules inside the `vendor` directory. These symlinks allow you to:
+
+-  Run a Magento installation with additional modules.
+-  Develop locally using the standard git workflow.
+
+You may need to ensure that there are no `Magento_PWA*` modules listed as `enabled` when you run `bin/magento module:status`. If there are, [follow the docs on how to enable modules](https://devdocs.magento.com/guides/v2.3/extension-dev-guide/build/enable-module.html).
+
+### Setting up the Git workflow
+
+To improve the developer experience even further, you can add these configurations as well:
+
+1. Exclude all the `ext` directories in the project's `.git` configuration:
+
+    ```bash
+    echo ext >> ./.git/info/exclude
+    ```
+
+1. Skip your project's root directory `composer.\*` files to avoid committing them by mistake:
+
+    ```bash
+    git update-index --skip-worktree composer.json
+    git update-index --skip-worktree composer.lock
+    ```
+
+    NOTE: You can reverse this operation anytime as needed:
+
+    ```bash
+    git update-index --no-skip-worktree composer.json
+    git update-index --no-skip-worktree composer.lock
+    ```
+
+## Cloud deployment extension installation
+
+1. Add https://repo.magento.com as a composer repository by adding the following to your cloud instances `composer.json` file.
+
+    ```json
+    "repositories": {
+        "repo": {
+            "type": "composer",
+            "url": "https://repo.magento.com"
+        }
+    },
+    ```
+
+1. Require in `magento/magento2-pwa` extension by adding the following to your cloud instances `composer.json` file.
+
+    ```json
+    "require": {
+        "magento/magento2-pwa": "0.0.1"
+    },
+    ```
+
+1. Ensure your `auth.json` file has valid credential for `repo.magento.com`.
+
+1. Run `composer update` to update your `composer.lock` file.
+
+1. Push the changes and deploy your cloud instance.
