+In most cases (if you are running vanilla Atmosphere), you don't need to use Incognito_RCM at all. The incognito feature is now built-in with Atmosphere - below shows how to enable it.
+
+_There are still some cases where Incognito_RCM is useful, but it is a brute-force method intended for users who know what they are doing!_
+
+**Enable incognito-mode in Atmosphere**
+
+In your Atmosphere installation on your SD card, copy the file **exosphere.ini** from `SD:/atmosphere/config_templates` to the root of your SD card.
+
+Open the file in your preferred text editor and amend the values for **blank_prodinfo_emummc** and **blank_prodinfo_sysmms** from `0` to `1`.
+
+The final section in the file should look like this;
+
+```[exosphere]
+debugmode=1
+debugmode_user=0
+disable_user_exception_handlers=0
+enable_user_pmu_access=0
+blank_prodinfo_sysmmc=1
+blank_prodinfo_emummc=1
+allow_writing_to_cal_sysmmc=0
+```
+
+You can confirm that it is working by checking the serial number in the settings!
