 # lonelyradio
 
-Broadcast audio over the internet.
+Broadcast lossless audio over the internet.
 
 Decodes audio streams using [symphonia](https://github.com/pdeljanov/Symphonia).
 
 Optionally transcodes audio into and from FLAC using [flacenc-rs](https://github.com/yotarok/flacenc-rs/) and [claxon](https://github.com/ruuda/claxon).
 
-## Installation
+## Install server
-
-### Install music server
 
 ```shell
-cargo install --git https://github.com/ivabus/lonelyradio --tag 0.5.0 lonelyradio
+cargo install --git https://github.com/ivabus/lonelyradio --tag 0.6.0 lonelyradio
-```
-
-### Install CLI client
-
-```shell
-cargo install --git https://github.com/ivabus/lonelyradio --tag 0.5.0 monoclient
-```
-
-### Install GUI (Slint) client
-
-```shell
-cargo install --git https://github.com/ivabus/lonelyradio --tag 0.5.0 monoclient-s
 ```
 
 ## Run
 
 ```
-lonelyradio [-a <ADDRESS:PORT>] [-p|--public-log] [-w|--war] [-m|--max-samplerate M] [--xor-key-file FILE] [--no-resampling] [-f|--flac] <MUSIC_FOLDER>
+lonelyradio <MUSIC_FOLDER>
 ```
 
 All files (recursively) will be shuffled and played back. Public log will be displayed to stdout, private to stderr.
 
-`-m|--max-samplerate M` will resample tracks which samplerate exceeds M to M
+Look into `--help` for detailed info
-
-`--xor-key-file FILE` will XOR all outgoing bytes looping through FILE
-
-`-f|--flac` will enable (experimental) FLAC compression
 
 ### Clients
 
-[monoclient](./monoclient) is a recommended CLI player for lonelyradio that uses [monolib](./monolib)
+#### monoclient-x
+
+[monoclient-x](./monoclient-x) is a SwiftUI player for lonelyradio for iOS/iPadOS/macOS
+
+##### Build
+
+1. Build monolib with [xcframework](https://github.com/Binlogo/cargo-xcframework)
+2. Build monoclient-x using Xcode or `xcodebuild`
+
+#### monoclient-s
+
+[monoclient-s](./monoclient-s) is a GUI player for lonelyradio built with [Slint](https://slint.dev)
+
+
+##### Install
+
+```shell
+cargo install --git https://github.com/ivabus/lonelyradio --tag 0.6.0 monoclient-s
+```
+
+You may need to install some dependencies for Slint.
+
+Desktop integration will be added later.
+
+##### Build
+
+```
+cargo build -p monoclient-s
+```
+
+You may need to install some dependencies for Slint.

+# Other things
-
-### Other clients
-
-SwiftUI client is availible in [platform](./platform) directory.
 
 [monoloader](./monoloader) is a tool, that allows you to download individual audio tracks from lonelyradio-compatible servers.
 
 [monolib](./monolib) provides a C API compatible with lonelyradio for creating custom clients.
 
+The full protocol specification will be available later. If you would like to learn more about it now, please refer to the monolib.
+
 #### monolib API stability
 
 As lonelyradio has not yet reached its first major release, the API may (and will) break at any point.
 
 ### Microphone server
 
-Experimental server (lonelyradio-compatible) for streaming audio from your microphone is available in the [microserve](./microserve) crate.
+Experimental (and uncompatible with versions 0.6+) server (lonelyradio-compatible) for streaming audio from your microphone is available in the [microserve](./microserve) crate.
