# Help Menu

define HELP_MENU_HEADER
# Getting Started

To build this project, you must have the following installed:

- git
- make
- docker (19.03 or higher)
- buildx (https://github.com/docker/buildx)

## Creating a Builder Instance

The build process makes use of features not currently supported by the default
builder instance (docker driver). To create a compatible builder instance, run:

```
docker buildx create --driver docker-container --name local --buildkitd-flags '--allow-insecure-entitlement security.insecure' --use
```

If you already have a compatible builder instance, you may use that instead.

> Note: The security.insecure entitlement is only required, and used by the unit-tests target and targets which build container images
for applications using `img` tool.

## Artifacts

All artifacts will be output to ./$(ARTIFACTS). Images will be tagged with the
registry "$(REGISTRY)", username "$(USERNAME)", and a dynamic tag (e.g. $(REGISTRY_AND_USERNAME)/image:$(IMAGE_TAG)).
The registry and username can be overriden by exporting REGISTRY, and USERNAME
respectively.
