    created a modified version of Nimbus that resets the Friends test environment, and I created a GodMode9 script to
    automate save backups and switching save slots for the system modules.

    1. Reboot into GodMode9 and open the scripts menu.
    2. Run the `FriendsAccountSwitcher` script and select "Create a new save slot". Name the slot something descriptive
       like `pretendo_official`.
    3. Reboot into the Home Menu and open the Homebrew Launcher. From there, run the `ResetFriendsTestAccount.3dsx` app
       and press A when a white line appears at the top of the screen (the Nimbus GUI was removed).
    4. Open the Friend List applet. You should be "online" and have a new friend code that is different from your friend
-      code on the official servers.
-   5. Reboot into GodMode9 and open the scripts menu again.
-   6. Run the `FriendsAccountSwitcher` script and select "Create a new save slot" again. Name the slot something
-      descriptive like `local_server`.
-   7. You now have multiple test Friends accounts saved on your SD card at `sd:/gm9/out/friends_accounts/`. You can
-      switch between them by running the `FriendsAccountSwitcher` script, selecting "Create a new save slot", and
-      following the instructions.
+      code on the official servers. If you don't go online, you have not successfully connected to your selfhosted
+      server.
+   5. Reboot into GodMode9, run the `FriendsAccountSwitcher` script again, and select "Create a new save slot". Name the
+      slot something descriptive like `local_server`.
+   6. You now have multiple test Friends accounts saved on your SD card at `sd:/gm9/out/friends_accounts/`. You can
+      switch between them by running the `FriendsAccountSwitcher` script, selecting "Load a save slot", and following
+      the instructions.
       - Pay careful attention to the script's instructions. When loading a save slot, it will first save the current
         Friends and account system modules save data to the last-used save slot. Create a new slot if you don't want to
         overwrite your existing save data.
+      - **How does this work?** Each of your Friends saves contains both your prod (Nintendo) and test (Pretendo)
+        account data, as well as a config that determines which account is currently active. So, your
+        `pretendo_official` slot contains your Nintendo prod friends account, your Pretendo official test account, and a
+        config that makes the test account active. Your `local_server` slot contains the same prod account but a
+        different test account, and with the config making the test account active. (The account sysmodule save data
+        seems to work in a similar way.)
+      - If you save a slot with Nimbus set to Nintendo, your save slot's config will be set to making the prod account
+        active. You can switch it back to Pretendo by using Nimbus again.
+
 7. Open System Settings using your `local_server` Friends test account and create a new PNID or sign in to one you
    created on your Wii U or website.
