 # WordPress on App Engine Standard for PHP 7.2
 
-This is a simple command-line tool for downloading and configuring
-WordPress on App Engine Standard for PHP 7.2.
-
-## Common Prerequisites
-
-* Create a new Cloud Project using the [Cloud Console][cloud-console]
-* Enable Billing on that project
-* Install [Google Cloud SDK][gcloud-sdk]
-* [Enable Cloud SQL API][cloud-sql-api-enable]
-* Install [Composer][composer]
-
-### Create and configure a Cloud SQL for MySQL instance
-
-> **Note**: In this guide, we use `wordpress` for the instance name and the database
-name. We use `root` for the database user name.
-
-1. Create a new Cloud SQL for MySQL Second Generation instance with the following
-command:
-    ```sh
-    $ gcloud sql instances create wordpress \
-        --activation-policy=ALWAYS \
-        --tier=db-n1-standard-1
-    ```
-    > **Note**: you can choose `db-f1-micro` or `db-g1-small` instead of
-    `db-n1-standard-1` for the Cloud SQL machine type, especially for the
-    development or testing purpose. However, those machine types are not
-    recommended for production use and are not eligible for Cloud SQL SLA
-    coverage. See our [Cloud SQL SLA](https://cloud.google.com/sql/sla)
-    for more details.
-
-1. Next, create the database you want your WordPress site to use:
-    ```sh
-    $ gcloud sql databases create wordpress --instance wordpress
-    ```
-1. Finally, change the root password for your instance:
-    ```sh
-    $ gcloud sql users set-password root \
-        --host=% \
-        --instance wordpress \
-        --password=YOUR_INSTANCE_ROOT_PASSWORD # Don't use this password!
-    ```
-
-## Create or Update a WordPress project for App Engine
-
-The `wp-gae` command provides a convenient way for you to either create
-a new WordPress project or add the required configuration to an existing one.
-
-### Setup
-
-1. Download this repository and `cd` into the `appengine/php72/wordpress` directory
-    ```sh
-    $ git clone https://github.com/GoogleCloudPlatform/php-docs-samples.git
-    $ cd php-docs-samples/appengine/php72/wordpress
-    ```
-1. Install the dependencies in this directory using composer
-    ```sh
-    $ composer install
-    ```
-    > **Note** If you receive an error about extensions, install `phar` and `zip` PHP
-    extensions and retry.
-
-### Create a new WordPress Project
-
-To download WordPress and set it up for Google Cloud, run the `create` command:
-
-```sh
-$ php vendor/bin/wp-gae create
-```
-
-The command asks you several questions, please answer them. Then you'll have a
-new WordPress project. By default it will create `my-wordpress-project` in the
-current directory.
-
-> **Note**: To determine the region your database is in, run `gcloud sql instances describe wordpress`
-
-### Update an existing WordPress Project
-
-If you are migrating an existing project to Google Cloud, you can use the
-`update` command:
-
-```sh
-$ php vendor/bin/wp-gae update path/to/your-wordpress-site
-```
-
-The command asks you several questions, please answer them. This will copy
-[a few files][wp-gcp-files] and write the proper configuration. Then your
-WordPress project will be ready to deploy to Google Cloud!
-
-## Deploy to Google Cloud
-
-`cd` into the root of your WordPress project.
-
-```sh
-$ cd my-wordpress-project
-```
-
-Run the following command to deploy your project to App Engine:
-
-```sh
-$ gcloud app deploy app.yaml cron.yaml
-```
-
-Now you can access your site, and continue the installation step! The URL is
-https://PROJECT_ID.appspot.com/
-
-### Enable the Google Cloud Storage plugin
-
-To use the [Google Cloud Storage plugin][gcs-plugin] for media uploads, follow
-these steps.
-
-1. Configure the App Engine default GCS bucket for later use. The default App
-   Engine bucket is named YOUR_PROJECT_ID.appspot.com. Change the default Access
-   Control List (ACL) of that bucket as follows:
-    ```
-    $ gsutil defacl ch -u AllUsers:R gs://YOUR_PROJECT_ID.appspot.com
-    ```
-1. Go to the Dashboard at https://PROJECT_ID.appspot.com/wp-admin. On the
-   Plugins page, activate the `Google Cloud Storage plugin`.
-1. In the plugins Settings page, set your Bucket name to the bucket you
-   configured in Step 1.
-
-After activating the plugin, try uploading a media object in a new post
-and confirm the image is uploaded to the GCS bucket by visiting the
-[Google Cloud console's Storage page][cloud-storage-console].
-
-## Local Development
-
-To access this MySQL instance, use Cloud SQL Proxy. [Download][cloud-sql-proxy-download]
-it to your local computer and make it executable.
-
-Go to the [the Credentials section][credentials-section] of your project in the
-Console. Click 'Create credentials' and then click 'Service account key.' For
-the Service account, select 'App Engine app default service account.' Then
-click 'Create' to create and download the JSON service account key to your
-local machine. Save it to a safe place.
-
-Run the proxy by the following command:
-
-```sh
-$ cloud_sql_proxy \
-    -dir /cloudsql \
-    -instances=YOUR_PROJECT_ID:us-central1:wordpress \
-    -credential_file=/path/to/YOUR_SERVICE_ACCOUNT_JSON_FILE.json
-```
-
-> **Note**: Make sure to run the command under a user with write access in the `/cloudsql` directory. This proxy will use this folder to create a unix socket.
-
-Now you can access the Cloud SQL instance with the MySQL client in a separate
-command line tab.
-
-```
-$ mysql --socket /cloudsql/YOUR_PROJECT_ID:us-central1:wordpress -u root -p
-mysql> use database wordpress;
-mysql> show tables;
-mysql> exit
-```
-
-## Various Workflows
-
-### Install and Update WordPress, Plugins, and Themes
-
-Because the `wp-content` directory on the server is read-only, you have
-to perform all code updates locally. Run WordPress locally and update the
-plugins and themes in the local Dashboard, deploy the code to production, then
-activate them in the production Dashboard. You can also use the `wp-cli` utility
-as follows (be sure to keep the Cloud SQL proxy running):
-
-```
-# Install the wp-cli utility
-$ composer require wp-cli/wp-cli-bundle
-# Now you can run the "wp" command to update Wordpress itself
-$ vendor/bin/wp core update --path=wordpress
-# You can also update all the plugins and themes
-$ vendor/bin/wp plugin update --all
-$ vendor/bin/wp theme update --all
-```
-
-If you get the following error:
-
-```sh
-Failed opening required 'google/appengine/api/urlfetch_service_pb.php'
-```
-
-You can set a `WP_CLI_PHP_ARGS` environment variable to add
-`include_path` PHP configuration for wp-cli.
-
-```sh
-$ export WP_CLI_PHP_ARGS='-d include_path=vendor/google/appengine-php-sdk'
-```
-
-Then try the above commands again.
-
-### Remove Plugins and Themes
-
-First deactivate them in the production Dashboard, then remove them
-completely locally. The next deployment will remove those files from
-the production environment.
