+# Database Interface Spec
+
+This repository hosts the gRPC API for the Database standard. The interfaces defined in the [gRPC specification](database.proto) are meant to be the common interface for database object provisioning and management across various database object vendors.
+
+### Build and Test
+
+1. `database.proto` is generated from the specification defined in `spec.md`
+
+2. In order to update the API, make changes to `spec.md`. Then, generate `database.proto` using:
+
+```sh
+# generates cosi.proto
+make generate-spec
+```
+
+3. Do it all in 1 step:
+
+```
+# generates database.proto and builds the go bindings
+make all
+```
