+## Project setup
+
+The build downloads proto definitions
+from [open-telemetry/opentelemetry-proto](https://github.com/open-telemetry/opentelemetry-proto) and
+generates Java bindings:
+
+```shell
+./gradlew build
+```
+
+By default protos definitions will be downloaded for the latest published tag
+of `opentelemetry-proto-java`. For example, if the latest version
+is [0.20.0](https://github.com/open-telemetry/opentelemetry-proto-java/tree/v0.20.0), protos will be
+downloaded from
+the [v0.20.0 release](https://github.com/open-telemetry/opentelemetry-proto/releases/tag/v0.20.0).
+This can be overridden for the build or other gradle tasks (e.g. `publishToMavenLocal`)
+with `-Prelease.version.prop`:
+
+```shell
+./gradlew build -Prelease.version.prop=1.0.0

-Java code-generation for the OpenTelemetry Protocol Buffer data model. This repository contains
-workflows and build scripts that pull releases
-from [opentelemetry-proto](https://github.com/open-telemetry/opentelemetry-proto) to generate and
-build Java bindings and publish them to the

-on [Maven Central](https://search.maven.org/artifact/io.opentelemetry.proto/opentelemetry-proto). To
-do so, add the following as dependencies to your build configuration and replace `{{version}}` with
-your desired version.

-## Support
+# :warning: Not intended for production use :warning:
 
 The generated java bindings published from this repository are provided as-is.
 
-For generic documentation on how to use protobuf bindings,
-see [gRPC documentation](https://grpc.io/docs/languages/java/generated-code/)
-and [protobuf java documentation](https://protobuf.dev/reference/java/java-generated/).
+They are only used within the OpenTelemetry project by test suites
+and are not intended for production use.
 
-We have no intention of eventually publishing stable artifacts. If you need guarantees,
+There is no intention of eventually publishing stable artifacts. If you need any guarantees,
 please generate your own bindings,
 consulting [grpc codegen](https://grpc.io/docs/languages/java/generated-code/#codegen) and
