+# External Chaincode Builder and Launcher for Kubernetes
+
+This is chaincode builder that uses **Kubernetes bare pods** to build and run [Hyperledger Fabric](https://www.hyperledger.org/use/fabric) chaincode.
+
+The goal is to provide a Kubernetes-native way to handle external builders and launchers for Fabric chaincode deployments.
+
+---
+
+## Features
+
+- Uses Kubernetes bare pods for chaincode build and execution.
+- Integrates with the [Fabric Operator](https://github.com/hyperledger-labs/fabric-operator) and the [Fabric Operations Console](https://github.com/hyperledger-labs/fabric-operations-console).
+- Simplifies development workflows on Kubernetes without relying on Docker-in-Docker or privileged containers.
+
+---
+
+## Getting Started
+
+
+
+### Run the Tests
+
+Once Kubernetes is enabled on Docker Desktop:
+
+```bash
+go test ./...
+```
+
+---
+
+## Usage with Fabric Operator & Fabric Operations Console
+
+This external builder is compatible with both:
+
+- [Fabric Operator](https://github.com/hyperledger-labs/fabric-operator): Automates lifecycle management of Fabric networks on Kubernetes.
+- [Fabric Operations Console](https://github.com/hyperledger-labs/fabric-operations-console): A GUI-based tool to interact with and manage Hyperledger Fabric networks.
+
+You can configure this external chaincode builder within your operator or console deployment for custom chaincode packaging and deployment flows.
