+# I cant download anything
+
+If you are receiving errors like:
+- "OSError: [Errno 5] I/O error"
+- "OSError: [Errno 18] Cross-device link: '/tmp/random_id/name.webm' -> '/downloads/name.webm'
+- "Operation not permitted: '/downloads/name.webm'
+
+This indicates an error with your mounts and how they interact with the container. So, the basic solution is to do the following:
+
+```yaml
+services:
+  ytptube:
+    user: "${UID:-1000}:${UID:-1000}" # change this to your user id and group id, for example: "1000:1000"
+    image: ghcr.io/arabcoders/ytptube:latest
+    container_name: ytptube
+    restart: unless-stopped
+    environment:
+      - YTP_TEMP_PATH=/downloads/tmp
+      - YTP_DOWNLOAD_PATH=/downloads/files
+    ports:
+      - "8081:8081"
+    volumes:
+      - ./config:/config:rw
+      - ./downloads:/downloads:rw
+```
+
+Then run the following command to create the necessary directories and start the container:
+
+```bash
+mkdir -p ./config && mkdir -p ./downloads/{tmp,files} && docker compose -f compose.yaml up -d
+```
+
+Reference: [Issue #363](https://github.com/arabcoders/ytptube/issues/363)
+
+# I want to use link with playlist but only download the video not all the videos in the playlist?
+
+Simply create a preset, and in the `Command options for yt-dlp` field set `--no-playlist`. Then select the preset 
+whenever the link includes a playlist id.
+
+> [!NOTE]
+> You can also do the same via advanced options `Command options for yt-dlp` field, but presets are more convenient.
