+# Install tutorial (Jellyfin 10.10.x)
+
+Step-by-step installation of the Floatplane plugin through Jellyfin's own plugin
+catalogue. Every screenshot is from a stock Jellyfin 10.10.7 (linuxserver.io image).
+You need to be a Jellyfin **administrator**. Total time: about two minutes.
+
+Other ways to install (no screenshots): the `install.sh` script and a manual unzip —
+see the [README](https://gitea.brasse-pc.eu/brasse/jellyfin-plugin-floatplane#install).
+
+## 1. Add the plugin repository
+
+Open **Dashboard → Plugins → Repositories**. The list only contains the default
+"Jellyfin Stable" repository.
+
+![Repositories page](img/install-01-repositories.png)
+
+Press the **+** button next to the "Repositories" title. In the dialog, enter any name
+and this URL:
+
+```
+https://gitea.brasse-pc.eu/brasse/jellyfin-plugin-floatplane/releases/download/latest/manifest.json
+```
+
+![New repository dialog](img/install-02-add-repository.png)
+
+Press **Save**. Jellyfin warns that third-party repositories carry risks — confirm with
+**Ok**.
+
+![Confirm repository](img/install-03-confirm-repository.png)
+
+The repository now appears in the list.
+
+![Repository added](img/install-04-repository-added.png)
+
+## 2. Install the plugin from the catalogue
+
+Open **Dashboard → Plugins → Catalog** and scroll to the **Channels** section. The
+Floatplane card shows the plugin logo (the catalogue may take a few seconds to load).
+
+![Catalog](img/install-05-catalog.png)
+
+Click the card. The plugin page shows the description, the newest revision and the
+**Install** button.
+
+![Plugin page](img/install-06-plugin-page.png)
+
+Press **Install** and confirm the warning with **Install**.
+
+![Confirm install](img/install-07-confirm-install.png)
+
+## 3. Restart Jellyfin
+
+Back on **Dashboard → Plugins → My Plugins** the Floatplane card says **Status Restart**:
+the files are downloaded, but plugins are only loaded when the server starts.
+
+![Restart required](img/install-08-restart-required.png)
+
+Go to **Dashboard**, press **Restart** and confirm.
+
+![Restart confirm](img/install-09-restart.png)
+
+Wait half a minute and log in again. **My Plugins** now shows Floatplane with
+**Status Active**.
+
+![Plugin active](img/install-10-active.png)
+
+> If the Restart button is missing (some Docker set-ups), restart the container instead:
+> `docker restart jellyfin`.
+
+## 4. Configure the plugin
+
+Click the Floatplane card (or its ⋮ menu → Settings). The settings page opens with a
+status block at the top.
+
+**Session.** For playback the plugin needs your Floatplane session. Log in at
+floatplane.com in your browser, open the developer tools (F12) → *Application*
+(Chrome/Edge) or *Storage* (Firefox) → *Cookies* → `https://www.floatplane.com`, copy
+the **Value** of the cookie named `sails.sid` and paste it here. Press
+**Validate cookie** — the plugin answers with your user name and subscriptions.
+
+![Session settings](img/install-11-settings-session.png)
+
+**Extra creators** is optional: creators you are not subscribed to but want to browse
+(public listings work without a session, playback does not). The example uses
+`linustechtips`.
+
+![Extra creators](img/install-12-settings-creators.png)
+
+Press **Save** at the bottom. The status block reloads and lists the creators the plugin
+found, with their sub-channels.
+
+![Saved](img/install-13-settings-saved.png)
+
+## 5. Browse
+
+Go to the home screen: a **Floatplane** tile is now under *My Media*. Open it to see the
+creators, then "All videos" and the sub-channels. Playback needs the session from step 4.

+# Update tutorial
+
+How to get a newer version of the Floatplane plugin. Three ways, from least to most
+manual. All of them keep your settings (the configuration file is separate from the
+plugin folder).
+
+## Automatic (default)
+
+Jellyfin's scheduled task **Update Plugins** runs every night and installs newer
+versions of plugins that come from a configured repository — the Floatplane plugin
+ships with `autoUpdate` enabled. After an automatic update the plugin shows
+**Status Restart** in *My Plugins* until Jellyfin is restarted, so in practice: when
+you notice "Restart", restart the server.
+
+You can run the task by hand under **Dashboard → Scheduled Tasks → Update Plugins** (the
+▶ button).
+
+![Update Plugins task](img/update-06-update-plugins-task.png)
+
+## Through the catalogue (manual, with screenshots)
+
+**My Plugins** shows the installed version — here `0.2.0.0`.
+
+![Current version](img/update-01-current-version.png)
+
+Open **Dashboard → Plugins → Catalog**, scroll to **Channels** and click the Floatplane
+card. The plugin page lists the newest revision from the repository. If it is newer than
+what *My Plugins* shows, press **Install**.
+
+![Plugin page with newer revision](img/update-02-plugin-page.png)
+
+Confirm the warning.
+
+![Confirm](img/update-03-confirm.png)
+
+*My Plugins* now shows both versions: the new one with **Status Restart**, the old one
+as **Superceded**.
+
+![Restart required](img/update-04-restart-required.png)
+
+Restart Jellyfin (**Dashboard → Restart**, or `docker restart jellyfin`). After the
+restart the new version is **Active**; the old folder can be removed from the card's
+⋮ menu → *Uninstall* (optional — Jellyfin ignores superseded versions).
+
+![New version active](img/update-05-new-version.png)
+
+## With the install script (Docker / native hosts)
+
+The script downloads the newest release, verifies the checksum, replaces the plugin
+folder and restarts Jellyfin. Run it on the host (with `sudo` if the plugin directory
+needs it); `--dry-run` only prints what it would do.
+
+```bash
+curl -fsSL https://gitea.brasse-pc.eu/brasse/jellyfin-plugin-floatplane/releases/download/latest/install.sh | sh -s -- --dry-run
+curl -fsSL https://gitea.brasse-pc.eu/brasse/jellyfin-plugin-floatplane/releases/download/latest/install.sh | sh
+```
+
+Example dry-run output:
+
+```
+Floatplane plugin 0.2.0.5 (release latest)
+  package:   https://gitea.brasse-pc.eu/brasse/jellyfin-plugin-floatplane/releases/download/latest/floatplane_0.2.0.5.zip
+  checksum:  b5e6b689...
+  install:   /srv/docker/jellyfin/data/plugins/Floatplane_0.2.0.5
+  remove:    /srv/docker/jellyfin/data/plugins/Floatplane_0.2.0.0
+  owner:     1000:1000
+  restart:   docker restart jellyfin
+dry run - nothing changed
+```
+
+Variables: `TAG` (default `latest`, or `vX.Y.Z`), `JELLYFIN_CONTAINER` (default
+`jellyfin`; empty = native install), `JELLYFIN_CONFIG_DIR` (host path of the container's
+`/config`; read from `docker inspect` when omitted), `PLUGINS_DIR` (override the
+detected plugin directory), `PUID`/`PGID`.
+
+## Which version is installed?
+
+*My Plugins* shows the version under the plugin name, and the top of the plugin's
+settings page says `Plugin x.y.z.n`. Releases are listed at
+https://gitea.brasse-pc.eu/brasse/jellyfin-plugin-floatplane/releases — `latest` always
+carries the newest build from `master`, `vX.Y.Z` tags are versioned releases.
