+## Development environment
+
+There is a [Visual Studio Code Dev Container](https://code.visualstudio.com/docs/devcontainers/containers) which should help develop and test the k8s builder in a consistent development.
+It includes a preconfigured nano Fabric test network and minikube which can be used to run end to end tests.
+
+Build your latest k8s builder changes.
+
+```
+GOBIN="${PWD}"/.fabric/builders/k8s_builder/bin go install ./cmd/...
+```
+
+[Configure kubernetes](./docs/KUBERNETES_CONFIG.md) and export the kubeconfig path.
+
+```
+export KUBECONFIG_PATH="${HOME}/.kube/config"
+```
+
+Start the Fabric test network in the `.fabric/test-network-nano-bash` directory.
+
+```
+./network.sh start
+```
+
+In a new shell in the `.fabric/test-network-nano-bash` directory.

+```
+
+Set up the environment for running peer commands and check everything is working.
+
+```
+. ./peer1admin.sh
+peer channel list
+```
+
+Deploy the chaincode package as usual, starting by installing the k8s chaincode package.
+
+```shell
+peer lifecycle chaincode install go-contract-v0.7.2.tgz
+```
+
+Export a `PACKAGE_ID` environment variable for use in the following commands.
+
+```shell
+export PACKAGE_ID=$(peer lifecycle chaincode calculatepackageid go-contract-v0.7.2.tgz) && echo $PACKAGE_ID
+```
+
+Note: the `PACKAGE_ID` must match the chaincode code package identifier shown by the `peer lifecycle chaincode install` command.
+
+Approve the chaincode.

+```shell
