+# Crate driver
+
+This is a driver for the [Crate](https://crate.io) database. It is based on the Crate
+sql driver by [herenow](https://github.com/herenow/go-crate).
+
+This driver does not use transactions! This is not a limitation of the driver, but a 
+limitation of Crate. So handle situations with failed migrations with care!
+
+## Usage
+
+```bash
+migrate -url http://host:port -path ./db/migrations create add_field_to_table
+migrate -url http://host:port -path ./db/migrations up
+migrate help # for more info
+```
