As a theme developer, you start with a baseline theme and develop your own from there. Best practice is to start development using the SuiteCommerce Base Theme. This is available as a SuiteApp in NetSuite. Simply install this SuiteApp and activate it using the Manage Extensions Wizard. Use the theme developer tools to fetch the theme files into a theme development workspace and start developing.

The following tutorials assume that you have already activated the SuiteCommerce Base Theme using the Manage Extensions Wizard and fetched theme files using the theme developer tools.
