+Deploying to Platform.sh
+========================
+
+This step by step cookbook describes how to deploy a Symfony web application to 
+`Platform.sh`_ . You can read more about using Symfony with Platform.sh on the 
+official `Platform.sh documentation`_.
+
+Deploy an existing site
+-----------------------
+
+In this guide, we assume your codebase is already versioned with Git.
+
+Get a project on Platform.sh
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You need to subscribe to a `Platform.sh project`_. Choose the development plan
+and go through the checkout process.
+
+Once your project is ready, give it a name and choose: **Import an existing
+site**.
+
+Prepare your Application
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+To deploy your Symfony application on Platform.sh, you simply need to add a 
+``.platform.app.yaml`` at the root of your Git repository which will tell
+Platform.sh how to deploy your application (read more about `Platform.sh 
+configuration files`_).
+
+.. code-block:: yaml
+
+    # This file describes an application. You can have multiple applications
+    # in the same project.
+
+    # The name of this app. Must be unique within a project.
+    name: php
+
+    # The toolstack used to build the application.
+    toolstack: "php:symfony"
+
+    # The relationships of the application with services or other applications.
+    # The left-hand side is the name of the relationship as it will be exposed
+    # to the application in the PLATFORM_RELATIONSHIPS variable. The right-hand
+    # side is in the form `<service name>:<endpoint name>`.
+    relationships:
+        database: "mysql:mysql"
+
+    # The configuration of app when it is exposed to the web.
+    web:
+        # The public directory of the app, relative to its root.
+        document_root: "/web"
+        # The front-controller script to send non-static requests to.
+        passthru: "/app.php"
+
+    # The size of the persistent disk of the application (in MB).
+    disk: 2048
+
+    # The mounts that will be performed when the package is deployed.
+    mounts:
+        "/app/cache": "shared:files/cache"
+        "/app/logs": "shared:files/logs"
+
+    # The hooks that will be performed when the package is deployed.
+    hooks:
+        build: |
+          rm web/app_dev.php
+          app/console --env=prod assetic:dump --no-debug
+        deploy: |
+          app/console --env=prod cache:clear
+
+    # The configuration of scheduled execution.
+    # see http://symfony.com/doc/current/components/console/introduction.html
+    #crons:
+    #    symfony:
+    #        spec: "*/20 * * * *"
+    #        cmd: "php cron.php example:test"
+
+For best practices, you should also add a ``.platform`` folder at the root of
+your Git repository which contains the following files:
+
+.. code-block:: yaml
+
+    # .platform/routes.yaml
+    "http://{default}/":
+        type: upstream
+        upstream: "php:php"
+
+.. code-block:: yaml
+
+    # .platform/services.yaml
+    mysql:
+        type: mysql
+        disk: 2048
+
+Configure database access
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Platform.sh overrides your database specific configuration via importing the
+following file:
+
+.. code-block:: yaml
+
+    # app/config/parameters_platform.php
+    <?php
+    $relationships = getenv("PLATFORM_RELATIONSHIPS");
+    if (!$relationships) {
+      return;
+    }
+
+    $relationships = json_decode(base64_decode($relationships), TRUE);
+
+    foreach ($relationships['database'] as $endpoint) {
+      if (empty($endpoint['query']['is_master'])) {
+        continue;
+      }
+
+      $container->setParameter('database_driver', 'pdo_' . $endpoint['scheme']);
+      $container->setParameter('database_host', $endpoint['host']);
+      $container->setParameter('database_port', $endpoint['port']);
+      $container->setParameter('database_name', $endpoint['path']);
+      $container->setParameter('database_user', $endpoint['username']);
+      $container->setParameter('database_password', $endpoint['password']);
+      $container->setParameter('database_path', '');
+    }
+
+    # Hack.
+    ini_set('session.save_path', '/tmp/sessions');
+
+Make sure this file is listed in your *imports*:
+
+.. code-block:: yaml
+
+    # app/config/config.yml
+    imports:
+        - { resource: parameters_platform.php }
+
+Deploy your Application
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Now you need to add a remote to Platform.sh in your Git repository (copy the 
+command that you see on the Platform.sh web UI):
+
+.. code-block:: bash
+
+    $ git remote add platform kjh43kbobssae@git.eu.platform.sh:kjh43kbobssae.git
+
+Commit the Platform.sh specific files created in the previous section:
+
+.. code-block:: bash
+
+    $ git add .platform.app.yaml .platform/* 
+    $ git add app/config/config.yml app/config/parameters_platform.php
+    $ git commit -m "Adding Platform.sh configuration files."
+
+Push your code base to the newly added remote:
+
+.. code-block:: bash
+
+    $ git push -u platform master

+    ...
+
+That's it! Your application is being deployed on Platform.sh and you'll soon be
+able to access it in your browser.
+
+Deploy a new site
+-----------------
+
+You can start a new `Platform.sh project`_. Choose the development plan and go 
+through the checkout process.
+
+Once your project is ready, give it a name and choose: **Create a new site**.
+Choose the *Symfony* stack and a starting point such as *Standard*.
+
+That's it! Your Symfony application will be bootstaped and deployed. You'll soon
+be able to see it in your browser.
