-      Browserosaurus is an open-source (MIT license), Electron-based app for macOS. It
-      works by setting itself as the default browser; any clicked links in non-browser
-      apps are now sent to Browserosaurus where it’ll present you with a menu of
-      all your installed browsers. You may now decide which browser you’d like to
-      continue opening the link with.
