+
+## Cast your Linux audio to DLNA receivers
+
+You need `pactl`, `parec` and `ffmpeg` executables/dependencies on your system to run sblast.
+
+If you have all that then you can launch `sblast` and it looks like this when you run it:
+
+```
+[user@user sblast]$ ./sblast 
+----------
+DLNA receivers
+0: Kitchen
+1: Phone
+2: Bedroom
+3: Livingroom TV
+----------
+Select the DLNA device:
+[1]
+----------
+Audio sources
+0: alsa_output.pci-0000_00_1b.0.analog-stereo.monitor
+1: alsa_input.pci-0000_00_1b.0.analog-stereo
+2: bluez_output.D8_AA_59_95_96_B7.1.monitor
+3: sblast.monitor
+----------
+Select the audio source:
+[2]
+----------
+Your LAN ip addresses
+0: 192.168.1.14
+1: 192.168.122.1
+2: 2a04:ec00:b9ab:555:3c50:e6e8:8ea:211f
+3: 2a04:ec00:b9ab:555:806d:800b:1138:8b1b
+4: fe80::f4c2:c827:a865:35e5
+----------
+Select the lan IP address for the stream:
+[0]
+----------
+2023/07/08 23:53:07 starting the stream on port 9000 (configure your firewall if necessary)
+2023/07/10 23:53:07 stream URI: http://192.168.1.14:9000/stream.mp3
+2023/07/08 23:53:07 setting av1transport URI and playing
+```
+
+There are also `-debug` and `-headers` flags if you want to inspect your DLNA device. Also, `-log` to inspect what parec and ffmpeg are doing.
+
+### Non-interactive usage and extra flags
+
+```
+[ugjka@ugjka sblast]$ sblast -h
+Usage of sblast:
+  -bitrate int
+        audio format bitrate (default 320)
+  -bits int
+        audio bitdepth (default 16)
+  -channels int
+        audio channels (default 2)
+  -chunk int
+        chunk size in seconds (default 1)
+  -debug
+        print debug info
+  -device string
+        dlna device's friendly name
+  -dummy
+        only serve content
+  -format string
+        stream audio format (default "mp3")
+  -headers
+        print request headers
+  -ip string
+        host ip address
+  -log
+        log parec and ffmpeg stderr
+  -mime string
+        stream mime type (default "audio/mpeg")
+  -nochunked
+        disable chunked tranfer endcoding
+  -port int
+        stream port (default 9000)
+  -rate int
+        audio sample rate (default 44100)
+  -source string
+        audio source (pactl list sources short | cut -f2)
+  -useaac
+        use aac audio
+  -useflac
+        use flac audio
+  -uselpcm
+        use lpcm audio
+  -uselpcmle
+        use lpcm little-endian audio
+  -usewav
+        use wav audio
+  -version
+        show sblast version
+```
+
+## Tips and tricks
+
+* If you choose `sblast.monitor` as a source, you can send apps' audio to it (in pavucotrol or whatever applet you use) without streaming entire the desktop audio
+
+<img src="img.sblast.monitor.png" width=300px alt="sblast.monitor example" title="sblast.monitor example">
+
+* If none of the built-in codecs presets satisfy you, you can specify your own with `-mime` and `-format`. For example: `-mime audio/ac3 -format ac3`, `-mime audio/opus -format opus`, `-mime "audio/x-caf" -format caf` or `-mime "audio/mpeg" -format mp2`
+
+* You can change audio features with `-rate`, `-bits` and `-channels`, e.g. `sblast -rate 48000 -bits 24 -channels 1`
+
+## Building
+
+You need the `go` and `go-tools` toolchain, also `git`
+
+then execute:
+
+```
+git clone https://github.com/ugjka/sblast
+cd sblast
+go build
+```
+
+now you can run sblast with:
+```
+[user@user sblast]$ ./sblast
+```
+
+## Bins
+
+Prebuilt Linux binaries are available on the releases [page](https://github.com/ugjka/sblast/releases)
+
+## Why not use pulseaudio-dlna?
+
+This is for pipewire-pulse users.
+
+## Caveats
+
+* You need to allow port 9000 from LAN for the DLNA receiver to be able to access the HTTP stream, you can change it with `-port` flag
+* sblast monitor sink may not be visible in the pulse control applet unless you enable virtual streams
+
+## Trivia
+
+What on earth is "x-rincon-mp3radio"
