 ## Recovery
 
 ```
-nix-shell shell.nix --run ./build_recovery.sh
+./build_twrp.sh
 ```
 
+This builds the recovery inside the nix-shell FHS environment (shell.nix);
+the script re-executes itself there, so it works from the host even though
+`nix-shell --run` is broken by the `exec android-env` shellHook.
