 Run locally:

-docker build -t ndi-recorder
+# Install host dependencies
+apt install avahi-daemon avahi-utils
 
+# Build container
+docker build -t ndi-recorder .
+
+# Create a volume (change IP, device, and name) if you want to record to NFS server

 ## To do's
-- Test directly outputting to different server, e.g. H:/Opnames/wedstrijd/ or 192.168.216.52/Opnames
+- Easier changing of output folder
 - Timestamps & chopping:
-  - needs wrapper program to send `<record_chop filename="$OUTPUT_FOLDER$STREAM_NAME-$TIMESTAMP.mov"/>`)
+  - needs wrapper program to send `<record_chop filename="$OUTPUT_FOLDER/$STREAM_NAME-$TIMESTAMP.mov"/>`)
   - might be possible using a cronjob?
+  - doesn't seem like `ndi-record` responds to commands
