While we won't cover every file in the root Rock folder, below are a couple that you should be aware of. License.aspx: Rock uses several open-source projects in its core. Attribution for each of these projects is given here. We also note each of their licenses so as to show that our license (Apache) is not in conflict with theirs.Web.config: This is the core settings file for any ASP.Net application. Unless you know exactly what you're doing you should stay away from editing this file. Keep in mind that any change to this file will cause Rock to restart.
