-Tests  only on OpenPLi based image with  GM 990 Spark Reloaded receiver                                                               
-in my preferred linux distro (Last Linux Mint 18.* - MATE 64-bit)!
+## Minimum requirements
+*Python >= 3.5.2, GTK+ >= 3.16 with PyGObject bindings, python3-requests.*   
+   
+***Optional:** python3-gi-cairo, 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*!      
 
-Minimum requirements: Python >= 3.5.2 and GTK+ 3 with  PyGObject bindings.
+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 (experimental)
+**This program can also be run on macOS.**
+To work in this OS, you must use a [separate branch](https://github.com/DYefremov/DemonEditor/tree/experimental-mac).  
+**The functionality and performance of this version may be different from the Linux version!**
+ 
+## 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!
 
-Terrestrial and cable channels at the moment are not supported!
+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.   
+
+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.
+#### Command line arguments:
+* **-l** - write logs to file.
+* **-d on/off** - turn on/off debug mode. Allows to display more information in the logs.

+demon-editor for Debian
+----------------------
+DemonEditor
+Enigma2 channel and satellites list editor for GNU/Linux.
+
+Experimental support of Neutrino-MP or others on the same basis (BPanther, etc).
+Focused on the convenience of working in lists from the keyboard. The mouse is also fully supported (Drag and Drop etc).
+
+Main features of the program:
+   Editing bouquets, channels, satellites.
+   Import function.
+   Backup function.
+   Extended support of IPTV.
+   Support of picons.
+   Downloading of picons and updating of satellites (transponders) from the web.
+   Import to bouquet(Neutrino WEBTV) from m3u.
+   Export of bouquets with IPTV services in m3u.
+   Assignment of EPGs from DVB or XML for IPTV services (only Enigma2, experimental).
+   Preview (playback) of IPTV or other streams directly from the bouquet list (should be installed VLC).
+
+Keyboard shortcuts:
+    Ctrl + Insert - copies the selected channels from the main list to the the bouquet beginning or inserts (creates) a new bouquet.
+    Ctrl + BackSpace - copies the selected channels from the main list to the bouquet end.
+    Ctrl + X - only in bouquet list. Ctrl + C - only in services list.
+    Clipboard is "rubber". There is an accumulation before the insertion!
+    Ctrl + E - edit.
+    Ctrl + R, F2 - rename.
+    Ctrl + S, T in Satellites edit tool for create satellite or transponder.
+    Ctrl + L - parental lock.
+    Ctrl + H - hide/skip.
+    Ctrl + P - start play IPTV or other stream in the bouquet list.
+    Ctrl + Z - switch (zap) the channel (works when the HTTP API is enabled, Enigma2 only).
+    Ctrl + W - switch to the channel and watch in the program.
+    Space - select/deselect.
+    Left/Right - remove selection.
+    Ctrl + Up, Down, PageUp, PageDown, Home, End - move selected items in the list.
+    Ctrl + O - (re)load user data from current dir.
+    Ctrl + D - load data from receiver.
+    Ctrl + U/B upload data/bouquets to receiver.
+    Ctrl + F - show/hide search bar.
+    Ctrl + Shift + F - show/hide filter bar.
+
+    For multiple selection with the mouse, press and hold the Ctrl key!
+
+Minimum requirements:
+    Python >= 3.5.2 and GTK+ >= 3.16 with PyGObject bindings, python3-requests.
+
+Important:
+    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!
+
+    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.
