+In your `config.override.mk` set the following to variables:
+```Makefile
+FPC_CCENV_IMAGE=ubuntu:22.04
+ERCC_GOTAGS=
+```
+This configuration sets a standard Ubuntu image as alternative to our `fabric-private-chaincode-ccenv` image and overrides the default build tags we use to build `ercc`.
+
+Next you can build `ercc` using the following command:
+```bash
+GOOS=linux make -C $FPC_PATH/ercc build docker
+```
+
+For building a chaincode, for instance `$FPC_PATH/samples/chaincode/kv-test-go`, just run: 
+```bash
+GOOS=linux make -C $FPC_PATH/samples/chaincode/kv-test-go with_go docker
+```
+
+You can test your FPC chaincode easily with one of the [sample deployments](samples/deployment) tutorials.
+We recommend to start with [the-simple-testing-network](samples/deployment/fabric-smart-client/the-simple-testing-network).

+Notes:
+- On Mac use a recent version of bash (`brew install bash`).
+- TODO more to come
