+    // with this we can very easily fetch the latest version of FlightCore
+    // and redirect to it, without having to update any version numbers on
+    // every release, simply change the search query to either "win-setup"
+    // or "appimage", without a query you will be redirect to the release
+    // page instead of the download
+    //
+    // so generally a request would look like this:
+    // 
+    //    r2northstartools.github.io/FlightCore/index.html?win-setup
+    //
+    // or
+    //
+    //    r2northstartools.github.io/FlightCore/index.html?appimage
+    //
+    // and to redirect to the release page:
+    //
+    //    r2northstartools.github.io/FlightCore/index.html
