+## Troubleshooting
+-   It says that it isn't connected/ip in the footer is not defined.  
+    - You must set the server ip address in the settings section (gear icon).
+-   The download  doens't start.  
+    - As before server address is not specified or simply yt-dlp process takes a lot of time to fire up. (Forking yt-dlp isn't fast especially if you have a lower-end/low-power NAS/server/desktop where the server is running)
+-   Background jobs are not retrieved.
+    -   As before forking yt-dlp isn't fast so resuming _n_ background jobs takes _n_*_time to exec yt-dlp_ Just have patience.

+## FAQ
+-   Will it availabe for Raspberry Pi/ generic ARM devices?
+    - Yes, absolutely a multi-arch docker image is planned to be released.  
+      Alternatively use the **non-docker / Manual** installation method.  
+      If you plan to use it on a Raspberry Pi ensure to have fast and durable storage.
+-   Why the docker image is so heavy?
+    - Originally it was 1.8GB circa, now it has been slimmed to ~340MB compressed. This is due to the fact that it encapsule a basic Alpine linux image + FFmpeg + Node.js + Python3 + yt-dlp.
+-   Am I forced to run it on port 3022?
+    -   Well, yes (until now).
