+- Due to an osu!stable bug you need to sign-in **twice** across different osu! launches before your credentials for a
   specific server can be saved.
 - Shortcuts will have to be recreated if you've moved the location of the following:
     - `osu!` install directory
     - `osu-switcher.exe`
 
+## How does it work?
+
+osu! stores auth details in the `<osu-dir>/osu!.<username>.cfg` config file, under the following keys:
+
+- `Username` -> Public username
+- `Password` -> A login session specific key
+- `CredentialEndpoint` -> The auth server these credentials are meant for
+
+In short, the created shortcuts launch this switcher program, which backs up the credentials for the currently logged in
+server, and restores saved credentials for the target server from the custom `<osu-dir>/osu!switcher.ini` config file.
+
+Additionally, in the `<osu-dir>/osu!.db` binary database, there is an additional field that stores the last
+login username. If this does not match the `Username` from the config file, then you are automatically logged out.
+This is changed when switching logins as well.

 ## Disclaimer
 
-This is NOT a tool for multiaccounting.
-I am an [akatsuki](https://akatsuki.pw) player and find it very annoying to change accounts between servers.
+**This is NOT a tool for multi-accounting.**\
+I often play on private servers often find it annoying to keep re-entering my login details.
 This tool allows you to switch accounts *between* servers, not on the same server.
+This tool does not spoof any device fingerprinting in order to bypass multi-account detection.
