Update README

Use bat query param rather than header when streaming as headers not passed in HEAD requests from sonos. Improve handling of failures when fetching coverArt to return undefined rather than throwing exception (#59 )
Add additional debug logging around /stream endpoint

 ## Initialising service within sonos app

- Configure bonob, make sure to set BONOB_URL. **bonob must be accessible from your sonos devices on BONOB_URL, otherwise it will fail to initialise within the sonos app, so make sure you test this in your browser by putting BONOB_URL in the address bar and seeing the bonob information page**

 - Start bonob, 
 - Open sonos app on your device
 - Settings -> Services & Voice -> + Add a Service
- Select your Music Service, default name is 'bonob', can be overriden with configuration BONOB_SONOS_SERVICE_NAME
+- Select your Music Service, default name is 'bonob', can be overriden with configuration BNB_SONOS_SERVICE_NAME
 - Press 'Add to Sonos' -> 'Linking sonos with bonob' -> Authorize
- Your device should open a browser and you should now see a login screen, enter your navidrome credentials
+- Your device should open a browser and you should now see a login screen, enter your subsonic clone credentials
 - You should get 'Login successful!'
 - Go back into the sonos app and complete the process
- You should now be able to play music from navidrome
- Within navidrome a new player will be created, 'bonob (username)', so you can configure transcoding specifically for sonos

+## A note on transcoding

+tldr; Transcoding to mp3/m4a is not supported as sonos devices will not play the track.  Transcoding to flac works however, use BNB_SUBSONIC_CUSTOM_CLIENTS=audio/flac if you want to transcode flac->flac ie. to downsample HD flacs (see below).
+
+Sonos devices are very particular about how audio streams are presented to them, see [streaming basics](https://developer.sonos.com/build/content-service-add-features/streaming-basics/).  When using transcoding both Navidrome and Gonic report no 'content-length', nor do they support range queries, this will cause the sonos device to fail to play the track. 
+
+## Cusomisation
+
+### Audio File type specific transcoding options within Subsonic
+
+In some situations you may wish to have different 'Players' within you Subsonic server so that you can configure different transcoding options depending on the file type.  For example if you have flacs with a mixture of frequency formats where not all are supported by sonos [See issue #52](https://github.com/simojenki/bonob/issues/52) & [Sonos supported audio formats](https://developer.sonos.com/build/content-service-add-features/supported-audio-formats/)
+
+In this case you could set;
+
+```bash
+BNB_SUBSONIC_CUSTOM_CLIENTS="audio/flac"
 ```
-e BONOB_ICON_FOREGROUND_COLOR=white \
-e BONOB_ICON_BACKGROUND_COLOR=darkgrey
+
+This would result in 2 players in Navidrome, one called 'bonob', the other called 'bonob+audio/flac'.  You could then configure a custom flac transcoder in Navidrome that re-samples the flacs to a sonos supported format, ie [Using something like this](https://stackoverflow.com/questions/41420391/ffmpeg-flac-24-bit-96khz-to-16-bit-48khz);
+
+```bash
+ffmpeg -i %s -af aresample=resampler=soxr:out_sample_fmt=s16:out_sample_rate=48000 -f flac -
 ```
+
+### Changing Icon colors
+
+```bash
+-e BNB_ICON_FOREGROUND_COLOR=white \
+-e BNB_ICON_BACKGROUND_COLOR=darkgrey
+```
