+## Folder Layout
+
+The recommended folder layout keeps the various pieces necessary within one folder.  
+This top folder will be shared with Sonarr or Radarr, while Jellyfin and Transmission respectively only need a partial view.

+
+## Sonarr
+
+[shroot]
+
+```
+podman run -d \
+    --name sonarr \
+    -p 8989:8989 \
+    -v /mnt/sonarr:/config \
+    -v /mnt/arrdata:/mnt/arrdata \
+    cr.hotio.dev/hotio/sonarr:latest
+```
+
+[/shroot]
+
+Configure an application in Prowlarr that points to Sonarr

+
+## Radarr
+
+[shroot]
+
+```
+podman run -d \
+    --name radarr \
+    -p 7878:7878 \
+    -v /mnt/radarr:/config \
+    -v /mnt/arrdata:/mnt/arrdata \
+    cr.hotio.dev/hotio/radarr:latest
+```
+
+[/shroot]
+
+Same as with Sonarr, configure Radarr as an application in Prowlarr
