This is a barebones example of how to create a starter template for sanity.io/create.
It contains a template folder with a simple web site and the studio. These will be set up as two projects on Netlify from the same repo. The configuration is found in sanity-template.json.
Go to our work in progress documentation for starter templates.
Let us know in the #beta channel in our Slack community if you try this out and have questions.
