+# Shell
+
+[AppShellModule](../../app/src/app/app-shell/app-shell.module.ts) is designated as a main layout for the application.
+
+I order to attach routes to appShell, `withRoutes(routes: Routes | AppShellRoutesConfig)` method should be used.
+
+Passed routes are going to be attached to [shell main route](../../app/src/app/app-shell/app-shell.routes.ts)
+
+If you would like to provide custom app guard, you can provide your own using [SHELL_AUTH_TOKEN](../../app/src/app/app-shell/app-shell.routes.ts)
+
+## Shell Service
+
+In order to use `shell`, you need to provide `SHELL_APP_SERVICE` which provides necessary options for shell component to work.
