 ### Setting up an external database for use with MagicBox
 
 > The MagicBox is a transient thing; it lasts only until the container is stopped.  Users must configure an external database if they wish for their world to persist.
+
+For utility we will use a MySQL container for this purpose.
+
+`$ docker pull mysql:latest`
+
+Now let's spin up our new mysql server.  Choose your own root password here.
+
+`$ docker run --name mysql -p 3306:3306 -v mysql_volume:/var/lib/mysql/ -d -e "MYSQL_ROOT_PASSWORD=ROOTPASS" mysql`
+
+Copy the mb.data/magicbanesql.conf file making the following edits.
+
+- Set your own password
+- Change localhost to the wildcard.  (Allows remote access)
+
+```console
+SET GLOBAL log_bin_trust_function_creators = 1;
+CREATE USER 'magicbox'@'%' IDENTIFIED BY 'YOURPASSHERE';
+CREATE DATABASE magicbane;
+GRANT ALL PRIVILEGES ON *.* TO 'magicbox'@'%';
+FLUSH PRIVILEGES;
+```
