+Bluefin and Silverblue, use [Distrobox](https://distrobox.it/) and run the install and build steps

+From the repository root, follow the launcher configure, build and install steps in

+Qt libraries and plugins are bundled. You can also launch directly on a Fedora Atomic host

+# Notification localization
+
+Trophy notification subtitles use the configured console language. Trophy names still come
+from the game's metadata. The launcher trophy dialogs are unchanged.
+
+Edit `assets/localization/<locale>.json`, using flat UTF-8 string values:
+
+```json
+{
+  "trophy.toast.earned": "Trophy earned!"
+}
+```
+
+CMake converts the catalogs into C++ byte arrays in the build directory. The emulator parses
+the embedded catalogs once and falls back to `en-US.json` for missing translations. No language
+files or translation service are needed at runtime. Rebuild after editing a catalog.
+
+For local testing, rebuild `kyty_emulator`, choose a game's Console Language in the launcher,
+and unlock a trophy with notifications enabled. Installed system fonts provide non-Latin
+glyphs; the selected language needs an appropriate font on the host.
