+# Booking Server Skeleton for PHP
+
+This is a reference implementation of
+[API v3 Booking Server](https://developers.google.com/maps-booking/guides/end-to-end-integration/implement-booking-server)
+based on PHP
+
+### Prerequisites
+
+Requires an installation of
+
+*   [Apache](https://httpd.apache.org/)
+*   [PHP](https://secure.php.net/)
+
+## Getting Started
+
+The Booking Server is implemented using PHP and Apache. To properly route the
+requests it makes use of the
+[.htaccess file](https://httpd.apache.org/docs/current/howto/htaccess.html) so
+make sure that
+[AllowOverride](https://httpd.apache.org/docs/current/mod/core.html#allowoverride)
+is enabled for the directory.
+
+It is required that you implement an SSL certificate and have all requests
+served over https. If your server does not already have an SSL certificate setup
+you can review the
+[Apache SSL/TLS documentation](https://httpd.apache.org/docs/2.4/ssl/ssl_howto.html).
+
+The implementation is also not using protocol buffer libraries, but instead
+relies on simple JSON serialization methods.
+
+To download the project execute the following command:
+
+    git clone https://maps-booking.googlesource.com/php-maps-booking-rest-server-v3-skeleton
+
+The entire code base consists of only three files:
+
+*   .htaccess instructs apache to route all of the /v3/ requests through
+    bookingserver.php
+*   bookingserver.php handles the request logic, including authentication
+*   apiv3methods.php has the methods implementing API v3 interface
+
+After you downloaded the files you should place them in a servable directory.
+Note that whichever directory you put them in will automatically be the parent
+to the /v3/ folder (which you do not need to create).
+
+## Testing your Booking Server
+
+For instructions on how to test your booking server refer to the
+[booking server testing](https://developers.google.com/maps-booking/guides/end-to-end-integration/test-booking-server)
+section of our documentation. It is reccomended that you download and run the
+[booking test utility](https://maps-booking.googlesource.com/maps-booking-v3/).
+To install it, follow the provided installation instructions in its README page.
