Add documentation for my OpenTools-specific WooCommerce container for Docker

README.md

 # ecommerce-woocommerce-data
 
 Docker data container for woocommerce.
+
+- Container uses supervisord to run WordPress and WooCommerce with apache and mysql. MySQL is optionally running in the same container and make sure both keep running
+
 Contains wordpress + woocommerce installation script.
+
+- Use the apache image and install wordpress manually
+- Optionally connect to a mysql container or install mysql directly inside the WooCommerce container (default user/password: wordpress/wordpress)
+- Add script to install WooCommerce, and also to setup an Apache virtual host (.test TLD), using sudo
+
+## Requirements
+
+You can optionally link to a mysql container, but this container also provides a running MySQL/MariaDB instance that will be used if no mysql container is linked. So there are NO external requirements, except maybe Apache set up for proxying requests.
+
+## How to run an WooCommerce test container
+
+    ./wc-docker-create.sh CONTAINERNAME 8000 "OpenTools Ordernumber TEST"
+
+This will run the install script to 
+* Start a instance of the docker-woocommerce image with name "wc-CONTAINERNAME" on port 8000 (configurable)
+* The wc-docker-create.sh script currently links my development directories for various OpenTools plugins as volumes. If you don't want this, please remove the corresponding -v options in the script.
+* The internal MariaDB database server will be used (default root user/pw: root/root) with database "wc_CONTAINERNAME" and wordpress database user/password: wordpress/wordpress
+* An Apache vhost (domain wc-CONTAINERNAME.test, which is assumed to point to localhost, i.e. 127.0.0.1) is added to /etc/apache2/sites-enabled/development.conf. This vhost will simply reverse-proxy to http://127.0.0.1:$PORT/)
+* WooCommerce is installed with URL http://wc-CONTAINERNAME.test and the given site name.
+  * Wordpress user/password is opentools/opentools
+  * Latest WooCommerce and debug-bar plugins are installed
+  * A tiny disable-curl plugin is provided and activated, because otherwise downloading plugins from the Web would fail... (curl does not seem to have updated some API...)
+  * When asked on the console, open the wc-setup page to create the WC pages and setup shipping, payment and localization options:
+
+    http://wc-CONTAINERNAME.test/wp-admin/admin.php?page=wc-setup or http://127.0.0.1:$PORT/wp-admin/admin.php?page=wc-setup
+
+  * Press Enter afterwards. This will create a simple main menu with the most important WC entries, set up the Shop as start page and insert a dummy product for testing purposes
