+## About database drivers
+
+Our docker images come with little to zero database driver support since
+each envrionment requires different drivers, and mataining a build with
+wide database support would be both challenging (dozens of databases,

+build times, larger images, lower layer cache hit rate, ...).

+add database support for the database you need.
