+## Docker quickstart
+
+To quickly try out the plugin, without affecting your other WordPress installations:
+
+ - [install Docker](http://docker.com)
+ - `docker run --name devmysql -e MYSQL_ROOT_PASSWORD=banana -d mariadb` # run a MySQL container for the WordPress one to later use
+ - `docker run --name plugindevwp --link devmysql:mysql -p 8080:80 -d wordpress` # run the official WordPress image, linking to your MySQL instance
+ - `docker exec -it plugindevwp bash` # get CLI access to the container
+ - `docker-php-ext-install zip` # install zip extension for PHP, which the plugin requires
+ - `service apache2 reload` # enables new extension to be used
+ - `exit` # leave the container's shell
+ - `docker ps` # get WordPress container's id so you can connect from the host
+ - `docker inspect __yourcontainerid__ | grep Address` # get IP for connecting in your browser
+ - open IP in browser and perform WP installation as usual
+ - install the plugin by searching by its name, else go back into container and use `wp-cli` method
+
