FAQ

Does this apply to websites and web apps? Yes. The term "Work" covers any code, markup, stylesheets, scripts, or configuration files used to build or run a website or application.

Can I use this in proprietary software internally? Yes. The ShareAlike obligation only triggers when you distribute the work to others.

Can I dual-license? The license text does not explicitly allow dual-licensing. If you need that, consider using a standard license or adding a specific clause.
