+# MariaDB setup
+
+This directory hosts any new SQL table added to genenetwork3. When preparing
+statements, be sure to follow [this](https://www.sqlstyle.guide/) style guide.
+
+Also, not that in some tables, we use the json data format; therefore make
+sure you have MariaDB version 10.2 and later which include a range of JSON
+supporting functions. Read about that
+[here](https://mariadb.com/resources/blog/json-with-mariadb-10-2/)
