Some translation work. Otherwise, good work by the mirrorer! A lifesaver.

 ## Introduction
 
 PicoKey firmware allows to convert a Raspberry Pico into a Hardware Security Module (HSM), FIDO2 device or OpenPGP card, to store private and secret keys, perform signing and ciphering operations, without exposing the key.

+"""Interactive commissioning helper for PicoKey
+
+This script collects commissioning options (VID:PID, LED, options,
+product name, curves, etc.) and writes them to a JSON file
+(`commission_config.json`). It can optionally attempt to apply the
+configuration when `--apply` is passed; the apply action is a safe
+stub and will ask for confirmation before performing any hardware
+changes.
+
+Usage:
+  python configure.py        # interactive
+  python configure.py --out mycfg.json
+  python configure.py --yes --out mycfg.json
+  python configure.py --apply  # will prompt before touching device
