+## Web UI
+
+Yoink includes a self-hosted web interface for browsing and downloading comics from your browser.
+
+### Running directly
+
+```shell
+yoink serve
+```
+
+By default the server listens on port `8080`. Use the `-p` flag to change it:
+
+```shell
+yoink serve -p 3000
+```
+
+### Running with Docker
+
+A `docker-compose.yml` is included for quick deployment:
+
+```shell
+docker compose up -d
+```
+
+Or with Podman:
+
+```shell
+podman compose up -d
+```
+
+The web UI is then available at `http://localhost:8080`.
+
+### Features
+
+- **Download queue** — paste a comic URL into the input bar and track download progress in real time
+- **Library grid** — browse your downloaded comics as a 150×300 cover grid
+- **Filter & sort** — filter by title and sort by newest, oldest, A–Z, or Z–A
+- **One-click download** — click any cover to download the `.cbz` archive directly
+
+### Library volume
+
+Downloaded comics are stored at the path set by `YOINK_LIBRARY`. When using Docker, mount this as a volume to persist your library across container restarts:
+
+```yaml
+# docker-compose.yml
+services:
+  yoink:
+    image: git.brizzle.dev/bryan/yoink-go:latest
+    ports:
+      - "8080:8080"
+    volumes:
+      - ./library:/library
+    environment:
+      - YOINK_LIBRARY=/library
+    restart: unless-stopped
