 ## 4. Using the template to create a new repo.
 
+> There are three steps: i.) create a new repo form the template; ii.) modify you repo settings so that GitHub pages are built from Actions.  iii.) Commit changes and trigger the GitHub Action and deployment. We recommend reading all instructions first.

 Let's assume you wanted to create a new discrete-event simulation model of cancer services.  
 
 1. The first step is to copy the template. Click on the green "use this template" button in the top right and select "create a new repository"
 2. You will be prompted to enter a name of the repository - e.g. `cancer_model` - and a short description
 3. Click on "Create Repository"

+By default the build is trigged on any commit to the `main` branch.  Push a small commit and it will trigger the build.  This will take a few minutes.  Your site will be published under https://{USERNAME}.github.io/{DEMO_REPO_NAME}

 The repo contains two environment files. To install more dependencies for your DES model and analysis you need to edit the ``environment.yml`` file.
