-## Getting Started
-
-### Cloning
-
-Clone the repository with submodules:
-
-```bash
-git clone --recurse-submodules https://github.com/stringintech/kernel-bindings-spec.git
-```
-**Note:** go-handler currently depends on go-bitcoinkernel via a submodule.
-
-
-### Building
-
-Use the provided Makefile to build the project:
-
-```bash
-# Build everything!
-make build
-```
-
-### Running Tests
-
-```bash
-# Run all conformance tests with both Go and Rust handlers
-make test
-
-# Run a specific test file with both Go and Rust handlers
-make test-single TEST=testdata/chainstate_basic.json
-```
+**Handler binaries** are not hosted in this repository. They must be implemented separately and should:
+- Implement the JSON protocol for communication with the orchestrator
+- Call the binding API to execute operations
+- Pin to a specific version/tag of this test repository
