This is currently very shoddy and is still a prototype. The Hayden.WebServer project includes a web application that will display threads archived with the Hayden backend.
Obviously you need to have a database set up with the appropriate schema. The creation script can be found in Hayden.WebServer/MySQLCreateDatabase.sql
Set the appropriate values for the connection string and file location in appsettings.json and it should start as-is. Do not run this unless you know your way around building a .NET Core app.
