+
+MongoDB's latest Docker image does not support Raspberry Pi 4.
+
+The workaround is to set the MongoDB version in the docker-compose to `4.4.6` like so:
+
+```
+image: mongo:4.4.6
+```
+
+So your full docker-compose.yml may look like this:
+
+```
+version: "2"
+services:
+    ytdl_material:
+        environment: 
+            ALLOW_CONFIG_MUTATIONS: 'true'
