 Lockpick_RCM is a bare metal Nintendo Switch payload that derives encryption keys for use in Switch file handling software like hactool, hactoolnet/LibHac, ChoiDujour, etc. without booting Horizon OS.
 
-Due to changes imposed by firmware 7.0.0, Lockpick homebrew can no longer derive the latest keys. In the boot-time environment however, there are fewer limitations.
+Due to changes imposed by firmware 7.0.0, Lockpick homebrew can no longer derive the latest keys. In the boot-time environment however, there is no such limitation.
 
 Usage
 =
 * Launch Lockpick_RCM.bin using your favorite payload injector
 * Upon completion, keys will be saved to `/switch/prod.keys` on SD
-* If the console has Firmware 7.x, the `/sept/` folder from [Atmosphère](https://github.com/Atmosphere-NX/Atmosphere/releases) or [Kosmos](https://github.com/AtlasNX/Kosmos/releases) release zip containing both `sept-primary.bin` and `sept-secondary.enc` must be present on SD or else only keyblob master key derivation is possible (ie. up to `master_key_05` only)
+* If the console has Firmware 7.x or higher, the `/sept/` folder from [Atmosphère](https://github.com/Atmosphere-NX/Atmosphere/releases) or [Kosmos](https://github.com/AtlasNX/Kosmos/releases) release zip must be present on SD or else only keyblob master key derivation is possible (ie. up to `master_key_05` only)
