 # Ledger wallets SDK for Rust Applications
 
-Crate that allows developing Ledger Nano apps in Rust with a default configuration.
+Crate that allows developing Ledger device apps in Rust with a default configuration.
 
 Contains:
 
 - some safe wrappers over common syscalls
 - IO abstractions
 - signature abstractions
+- UI libraries (the `ui` module for Nano (S/SP/X) apps, `nbgl` module for Stax and Flex apps)
 
-This SDK is incomplete in the sense that wrappers are currently missing, and not all wrappers have a nice Rust abstraction on top, but two apps were made using it:
