+## Installing the daemon
+
+Strata is two parts: the GNOME Shell extension and a small background daemon
+(`strata-daemon`) that does the storage, search, and thumbnailing. Installing
+the extension from [GNOME Extensions](https://extensions.gnome.org/extension/10291/strata/)
+is only half the setup; **without the daemon the extension does nothing.**
+
+Install the daemon with whichever fits your system:
+
+- **Arch (AUR):** `paru -S strata-daemon` (or `strata-daemon-git` for the latest `main`).
+- **From source:**
+
+  ```sh
+  git clone https://github.com/Edu4rdSHL/Strata.git
+  cd Strata
+  make install-daemon    # builds and installs to ~/.local/bin
+  ```
+
+  Make sure `~/.local/bin` is in your `$PATH`.
+
+Then log out and back in (Wayland) or `Alt+F2` → `r` (X11). The extension finds
+`strata-daemon` in `$PATH` and starts it automatically; no separate service is
+needed.
+
+For distro packages and the systemd user service, see [Install](#install).
+
 ## Requirements
 
 - GNOME Shell 50. Older releases may work if built from source but are not tested or supported.
