     <Description>EnvelopeGenerator.Web is an ASP.NET MVC application developed to manage signing processes. It uses Entity Framework Core (EF Core) for database operations. The user interface for signing processes is developed with Razor View Engine (.cshtml files) and JavaScript under wwwroot, integrated with PSPDFKit. This integration allows users to view and sign documents seamlessly.</Description>
