+### Build AppImage (Universal Linux Package)
+
+**Prerequisites for AppImage:**
+```bash
+# On Arch/EndeavourOS
+sudo pacman -S fuse2
+
+# On Ubuntu/Debian
+sudo apt install fuse libfuse2
+```
+
+**Build the AppImage:**
+```bash
+chmod +x build-appimage.sh
+./build-appimage.sh
+```
+
+This creates a universal `ProductivityCake-1.1.0-x86_64.AppImage` that works on:
+- ✅ Arch Linux / EndeavourOS / Manjaro
+- ✅ Ubuntu / Debian / Linux Mint
+- ✅ Fedora / RHEL / CentOS
+- ✅ openSUSE
+- ✅ Any Linux distro with FUSE support
