-Ability to import IPTV into bouquet (Neutrino WEBTV) from m3u files.

-### Minimum requirements:
-Python >= 3.5.2 and GTK+ 3 with PyGObject bindings.
-#### Note.
-To create a simple debian package, you can use the build-deb.sh                                                         
+***Optional:** python3-pil, python3-chardet.*                      
+## Installation and Launch
+* ### Linux                                                                                                          
+To start the program, in most cases it is enough to download the [archive](https://github.com/DYefremov/DemonEditor/archive/master.zip), unpack  
+and run it by double clicking on DemonEditor.desktop in the root directory,  
+or launching from the console with the command:```./start.py```                                                                                
+Extra folders can be deleted, excluding the *app* folder and root files like *DemonEditor.desktop* and *start.py*!      
 
-Tests only in image based on OpenPLi or last BPanther(neutrino) images with GM 990 Spark Reloaded receiver
-in my preferred linux distro (Last Linux Mint 18.* - MATE 64-bit)!
+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 [brew](https://brew.sh/).  
+Then install the required components via terminal:  
+```brew install python3 gtk+3 pygobject3 adwaita-icon-theme```                                                                  
+```pip3 install requests, pillow```
 
-#### Terrestrial and cable channels at the moment are not supported!
+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.  
+By downloading and using this packages you agree to the terms of this [license](http://www.gnu.org/licenses/gpl-3.0.html) and the possible inconvenience associated with this!**

+
+## Important
+The program is tested only with [openATV](https://www.opena.tv/) image and **Formuler F1** receiver in [Linux Mint](https://linuxmint.com/) (MATE 64-bit) distribution!  
+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!**
+If you need full set of the data, including *[satellites, terrestrial, cables].xml* (current files will be overwritten), 
+just load your data via *"File/Open"* and press *"Save"*. 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.
