Bump version to 1.0.6

The Web Store dashboard rejects any manifest containing a "key" field
("key field is not allowed in manifest"), but extension/manifest.json
pins one so unpacked/dev installs get a stable ID. Add a third release
asset with key stripped from a copy, so future releases have an
upload-ready zip without touching the pinned manifest.

-- A toolbar toggle enables **auto-capture**: while on, every download Chrome

 ## Requirements

+- Linux with KGet installed and running (or set to autostart)
-- One of: Google Chrome, Chromium, Brave, Vivaldi, Microsoft Edge
+- A Chromium-based browser: Chrome, Chromium, Brave, Vivaldi, or Edge

+
+**Arch / Manjaro**
+```bash
+sudo pacman -S kget python dbus libnotify kconfig
+```
+
+**Debian / Ubuntu / KDE neon**
+```bash
+sudo apt install kget python3 dbus-bin libnotify-bin kf6-kconfig-bin
+```
+
+**openSUSE**
+```bash
+sudo zypper install kget python3 dbus-1 libnotify-tools kconfig-tools
+```
+
+(`notify-send` and `kwriteconfig6` package names shift around between distro
+versions. If a command above fails, drop that one package and search your
+package manager for the binary name instead. Everything else still works
+without them.)
 
 ## Install
 
+1. Install the extension from the Chrome Web Store: **`<CHROME_WEB_STORE_URL>`**
+   *(placeholder, fill in once the listing is live)*.
+2. Click the extension's toolbar icon. The popup detects that the native
+   messaging host isn't set up yet and shows a one-line command; run it in a
+   terminal, then click "I ran it, check again" in the popup:
+   ```bash
+   curl -fsSL https://raw.githubusercontent.com/andwati/kget-capture/main/install-remote.sh | bash
+   ```
+   (or with `wget`: `wget -qO- https://raw.githubusercontent.com/andwati/kget-capture/main/install-remote.sh | bash`)
+
+   This downloads the latest release and runs its `install.sh`, which
+   registers the native host for every supported browser it finds installed
+   and prints any remaining setup warnings. No git clone required. If you'd
+   rather run it yourself: download and extract `kget-capture-vX.Y.Z.zip`
+   (the source archive, not `kget-capture-extension-vX.Y.Z.zip`) from the
+   [Releases page](https://github.com/andwati/kget-capture/releases), then
+   from inside that folder run `./install.sh` directly.
+3. Open your browser's download settings (`chrome://settings/downloads`,
+   `brave://settings/downloads`, etc.) and turn **off** "Ask where to save
+   each file before downloading". Chrome shows this dialog itself, before the
+   extension gets a chance to intercept the download, so this one-time change
+   is required (no extension API can do it for you).

+- `kget-capture-store-vX.Y.Z.zip`: same extension, but with `key` stripped,
+  for uploading to the Chrome Web Store dashboard. The Store rejects any
+  manifest containing `key` ("key field is not allowed in manifest") since
+  it assigns its own permanent ID on first publish, which won't match the
+  pinned ID (`keys/extension-id.txt`) the other zips use. After the first
+  successful Store publish, update `native-host/com.kget_capture.host.json`'s
+  `allowed_origins` to include the Store-assigned ID alongside the pinned
+  one, so both installs can reach the native host.
