It would be useful to add a "Building with Docker" section within the "Getting Started" section.

Also the following sections should be updated to be usable with Docker (using includeos-qemu image):

• Running unit tests
• Testing the installation
• Writing your first service
• Testing the example service

It should be verified also that hioa-cs/IncludeOS examples build and run using Docker (where possible this should be part of CI/CD chain).
