+### Installer (Inno Setup)
+
+Script: `installer/EbbesMemeClipboard.iss` (tracked; `installer/output/` is gitignored).
+Inno Setup 6 installs **per-user** to `%LocalAppData%\Programs\Inno Setup 6\`, not Program
+Files — that tripped up the first attempt to locate `ISCC.exe`.
+
+- Per-user install by default (no UAC), with a wizard page letting the user pick
+  "just me" vs "all users" (`PrivilegesRequired=lowest` +
+  `PrivilegesRequiredOverridesAllowed=dialog`).
+- Optional unchecked tasks: desktop icon, start-with-Windows.
+- **Don't double-compress.** Publishing with `EnableCompressionInSingleFile=false` and
+  letting Inno's LZMA2 do the work gives a ~51 MB setup vs ~70 MB, and the installed app
+  starts faster because there's no decompression at launch.
+- **Uninstall only removes the autostart entry if it points at the installed copy.** The
+  app's own Settings toggle writes the same `Run` value name, so an unconditional delete
+  would wipe out a portable build's autostart. This was a real bug caught in testing.
+- User data under `%AppData%\EbbesMemeClipboard` is deliberately preserved on uninstall;
+  only the re-downloadable `GifCache` is removed.
+- Verified end-to-end: silent install → files/shortcut/uninstall-entry present → app runs →
+  silent uninstall → everything removed, user data and unrelated autostart intact.
+- An installer does **not** fix SmartScreen warnings; only code signing does.
+
 Note: the published single-file exe takes **~10 seconds on first launch** before the tray
 icon appears (native library self-extraction to TEMP). Not a bug. Subsequent launches are
 faster.
