+## Building (Flatpak)
+
+1) Install flatpak
+
+2) Install runtime and SDK
+
+```
+flatpak --user install flathub \
+  org.freedesktop.Platform//25.08 \
+  org.freedesktop.Sdk//25.08 \
+  org.freedesktop.Sdk.Extension.rust-stable//25.08
+```
+
+3) Build flatpak
+
+```
+flatpak-builder --user --force-clean --repo=repo build-dir sh.nubo.immich-rs.yml
+```
+
+Add `--disable-rofiles-fuse` if running in an environment without FUSE.
+
+4) Export flatpak bundle
+
+```
