[csantanapr]

What is your environment, configuration, and command?

Linux 86

What did you do and What did you see instead?

git clone
cd idpbuilder
make build

It errors with

./hack/embedded-resources.sh
./hack/argo-cd/generate-manifests.sh: line 8: kustomize: command not found
./hack/gitea/generate-manifests.sh: line 11: helm: command not found

Additional Information. Logs.

We should document the dependencies in addition of golang, user needs kustomize and helm installed.
We can have the Makefile handle this installation, and also update the devcontainer.json file
