-### OS Icon Symlinks
-
-Some distributions share the same logo. Use symlinks instead of duplicating files:
-
-**Common symlinks:**
-
-```bash
-cd app/src/main/assets/osicons/
-
-# Arch-based distributions
-ln -s archlinux.svg manjaro.svg
-ln -s archlinux.svg endeavouros.svg
-
-# Ubuntu derivatives
-ln -s ubuntu.svg kubuntu.svg
-ln -s ubuntu.svg xubuntu.svg
-ln -s ubuntu.svg lubuntu.svg
-
-# Debian-based
-ln -s debian.svg kali.svg
-ln -s debian.svg raspbian.svg
-```
-
-**Why symlinks:**
-- Reduces APK size
-- Ensures consistency when upstream icon changes
-- Makes maintenance easier
-
-**Note:** Git tracks symlinks, so they work across all platforms when cloned.
