 ## Build
 
+If you want to run the build scripts with Podman, set the environment variable
+`export USE_PODMAN=true`

 To build all of the components together (recommended) for dev/test, run `./build_registry.sh` to build a Devfile Registry index image that is populated with the mock devfile registry data under `tests/registry/`.
 
 Once the container has been pushed, you can push it to a container registry of your choosing with the following commands:

 This folder contains the integration tests for the OCI-based Devfile Registry. The tests can be run against either a remote devfile registry (such as https://registry.stage.devfile.io), or a local devfile registry running your machine (such as in Minikube, or Docker Desktop).
 
 ## Build
+If you want to run the build scripts with Podman, set the environment variable
+`export USE_PODMAN=true`
 
 The integration tests can be built to either run in a Docker container, or locally on your machine.
