+# Database
+
+## Routines
+
+### Create
+
+    CREATE DATABASE `z` DEFAULT CHARACTER SET utf8mb4 DEFAULT COLLATE utf8mb4_unicode_ci;
+    CREATE USER 'z'@'%' IDENTIFIED BY 'legendofZ';
+    GRANT ALL PRIVILEGES ON z.* TO 'z'@'%'
+
+### Export
+
+Export database structure only:
+
+    $ mysqldump --routines --triggers --no-data -u z -p z | sed 's/ AUTO_INCREMENT=[0-9]*\b//' > create.sql
+
+Export data only:
+
+    $ mysqldump --no-create-info --skip-triggers --complete-insert -u z -p z > import.sql
+
+### Import
+
+Import database structure:
+
+    $ mysql -u z -p z < create.sql
+
+
+Import data:
+
+    $ mysql -u z -p z < import.sql
+
+
+_Note: You may need to delete all triggers before importing data and recreate them after the import (using triggers.sql)!_
+
+### Update
+
+There is currently no official database update procedure. As soon as we hit version 1.0 we will provide update scripts.
+
+However the following routine—which is a combination of the commands above—appears to be sufficient:
+
+    $ mysqldump --no-create-info --skip-triggers --complete-insert -u z -p z > ~/data.sql
+    $ mysql -u z -p z < db/create.sql
+    $ mysql -u z -p z < db/drop.sql
+    $ mysql -u z -p z < ~/data.sql
+    $ mysql -u z -p z < db/procedures.sql
+    $ mysql -u z -p z < db/triggers.sql
