-A Makefile is provided for ease of use. There are separate targets for each file generated, however `make` can be used to generate the final image and `make clean` can be used to clean up the workspace. The resulting ISO will be stored in the `build` directory.

+The Makefile contains all of the commands that are run in the action. There are separate targets for each file generated, however `make` can be used to generate the final image and `make clean` can be used to clean up the workspace. The resulting ISO will be stored in the `build` directory.

+
+### VSCode Dev Container
 There is a dev container configuration provided for development. By default it will use the existing container image available at `ghcr.io/jasonn3/build-container-installer:latest`, however, you can have it build a new image by editing `.devcontainer/devcontainer.json` and replacing `image` with `build`. `Ctrl+/` can be used to comment and uncomment blocks of code within VSCode.
 
 The code from VSCode will be available at `/workspaces/build-container-installer` once the container has started.
 
 Privileged is required for access to loop devices for lorax.
