 - `/spa resurrect name iPlayer` - resurrects the player whose name matches "iPlayer"
+
+### Popup/Menu Front End
+This front end provides access to the features via in-game radio menus.
+The main menu can be accessed by either running `spa menu` command in game console or typing `!spa menu` or `/spa menu` in game chat.
+To get this menu to show up, the client must have `admin.base` permission.
+
+### MoTD Front End
+This front end provides allows to administrate the server from the in-game MoTD screen, providing the most impressive experience with the interactive graphical interface.
+Its main screen shows up after running `spa motd` in game console or typing `!spa motd` or `/spa motd` in game chat.
+The admin must have `admin.base` permission to open the MoTD front end.
+
+### Web Front End
+Web front end is the only front end that allows admins to access Source.Python Admin features remotely, without even playing on the server.
+All it requires is a web-browser, then the admin can sign in via Steam OpenID.
+Web front end works in two modes: offline and online.
+
+- **online** mode provides an access to the regular set of the features;
+- **offline** mode works directly with the server database - this is useful, for example, for banning players even when the game server is offline.
+
+The switching between online and offline modes is done automatically.
