+To create a simple **debian package**, you can use the *build-deb.sh.* You can also download a ready-made *.deb package from the [releases](https://github.com/DYefremov/DemonEditor/releases) page.                                                 
+Users of **LTS** versions of [Ubuntu](https://ubuntu.com/) or distributions based on them can use [PPA](https://launchpad.net/~dmitriy-yefremov/+archive/ubuntu/demon-editor) repository.  
+A ready-made [package](https://aur.archlinux.org/packages/demoneditor-bin) is also available for [Arch Linux](https://archlinux.org/) users in the [AUR](https://aur.archlinux.org/) repository. 
+* ### macOS
+**This program can be run on macOS.**  
+To run the program on macOS, you need to install [Homebrew](https://brew.sh/).  
+Then install the required components via terminal:  
+```brew install python3 gtk+3 pygobject3 adwaita-icon-theme gtksourceview3```

-Terrestrial(DVB-T/T2) and cable(DVB-C) channels are only supported for Enigma2!                                                                                                
-Main supported **lamedb** format is version **4**. Versions **3** and **5** has only **experimental** support!                                                                                                                                                        
-For version **3** is only read mode available. When saving, version **4** format is used instead!                                                                                                                                             
+```pip3 install requests telnetlib-313-and-up --break-system-packages``` 
 
+*Optional:* ```brew install pillow python-chardet ffmpeg```  
 
+Launch is similar to Linux.
+
+You can also download the ready-made package as a ***.dmg** file from the [releases](https://github.com/DYefremov/DemonEditor/releases) page.  
+Recommended copy the package to the **Application** directory.  
+Perhaps in the security settings it will be necessary to allow the launch of this application!  
+
+* ### MS Windows  
+**Windows users can also run this program.**  
+One way is to use the [MSYS2](https://www.msys2.org/) platform. You can use [this](https://github.com/DYefremov/DemonEditor/blob/master/build/BUILD_WIN.md) quick guide.   
+In addition, you can download a ready-made build (**64-bit**) from the [releases](https://github.com/DYefremov/DemonEditor/releases) page.  
+
+**All builds may contain components distributed under the GPL [v3](http://www.gnu.org/licenses/gpl-3.0.html) or lower license.

+
+## Important
+Support for DVB-T/T2 and DVB-C channels for Neutrino is not fully implemented and has an experimental status.  
+
+Main supported *lamedb* format is version **4**. Versions **3** and **5** has only **experimental** support! For version **3** is only read mode available. When saving, version **4** format is used instead.   
+
+When using the multiple import feature, from *lamedb* will be taken data **only for channels that are in the selected bouquets!**
+When importing separate bouquet files, only those services (excluding IPTV) that are in the **current open lamedb** (main list of services) will be imported.
+
+**The built-in Telnet client does not support ANSI escape sequences!**
+
+For streams playback, this app supports [VLC](https://www.videolan.org/vlc/), [MPV](https://mpv.io/) and [GStreamer](https://gstreamer.freedesktop.org/). Depending on your distro, you may need to install additional packages and libraries.   
+#### Command line arguments:
+* **-l** - write logs to file.
+* **-d on/off** - turn on/off debug mode. Allows to display more information in the logs.
