In addition to building a Cloud Assembly template from a blank canvas, you can take advantage of existing code.

Cloud template cloning

To clone a template, go to Design, select a source, and click Clone. You clone a cloud template to create a copy based on the source, then assign the clone to a new project or use it as starter code for a new application.

Uploading and downloading

You can upload, download, and share cloud template YAML code in any way that makes sense for your site. You can even modify template code using external editors and development environments.

Note: A good way to validate shared template code is to inspect it in the Cloud Assembly code editor on the design page.
