    - Call it "mikropml_demo"
    - Make it Public
    - Don't check the box next to "Initialize this repository with a README"
    - Click the green "Create repository" button
  - Go to your command line and enter the following replacing `<your_github_id>` with your GitHub user id

		git clone git@github.com:SchlossLab/mikropml_demo.git
		cd mikropml_demo
		git reset --hard {{ page.start_hash }}
		git remote set-url origin git@github.com:<your_github_id>/mikropml_demo.git
		git push -u origin master
