+Add native Linux packaging support for FastSM, making installation much simpler on Debian/Ubuntu (.deb) and Fedora/RHEL (.rpm).
+
+### What's included
+
+- **New files:**
+  - `packaging/linux/build_packages.sh` � uses `fpm` to build both package formats from the PyInstaller output
+  - `packaging/linux/fastsm.desktop` � XDG desktop entry for app menu integration
+  - `packaging/debian/copyright` � Debian copyright metadata
+
+- **Modified files:**
+  - `build.py` � added `--package` flag that calls the packaging script on Linux
+  - `.github/workflows/build.yml` � installs fpm, runs packaging, uploads .deb/.rpm as artifacts, includes in release
+  - `README.md` � documents package install instructions
+  - `.gitignore` � ignores *.deb and *.rpm build artifacts
+
+### How it works in CI
+
+After the PyInstaller Linux build completes, `fpm` wraps the output into .deb and .rpm packages that:
+- Install the binary bundle to `/opt/FastSM/`
+- Register the desktop entry at `/usr/share/applications/fastsm.desktop`
+- Copy docs to `/usr/share/doc/fastsm/`
+- Declare runtime dependencies (GTK3, libnotify, SDL2, ALSA, PulseAudio, GStreamer)
+
+### Local usage
+```
+python build.py
+python build.py --package
+bash packaging/linux/build_packages.sh ~/app_dist/FastSM/dist/FastSM 0.5.0
+```
+
+### Note
+The copyright file currently says "All Rights Reserved" since the project has no LICENSE file. You may want to update `packaging/debian/copyright` and the `APP_LICENSE` variable in `build_packages.sh` once a license is chosen.
