-# Install
+# Install vimix
 
 Check the [Quick Installation Guide](https://github.com/brunoherbelin/vimix/wiki/Quick-Installation-Guide)
 
 ### Linux
 
-Download and install a release package from https://snapcraft.io/vimix
+Download and install a released [flatpak package](https://flathub.org/apps/details/io.github.brunoherbelin.Vimix)
 
-    $ snap install vimix
+    flatpak install --user vimix
     
-NB: You might need to setup the snap permissions.
+NB: Build your flatpak package to get the latest beta version; instructions are [here](https://github.com/brunoherbelin/vimix/tree/master/flatpak).
+    
+
+[![vimix](https://snapcraft.io/vimix/badge.svg)](https://snapcraft.io/vimix)
+
+Download and install a released [snap package](https://snapcraft.io/vimix) 
+
+    snap install vimix
+    
+Install the stable debian package (slower release frequency)
+
+    sudo apt install vimix
 
 ### Mac OSX
 
 Download and open a release package from https://github.com/brunoherbelin/vimix/releases
+
 NB: You'll need to accept the exception in OSX security preference.
 
+# Build vimix
+
 ## Clone
 
-    $ git clone --recursive https://github.com/brunoherbelin/vimix.git
+    git clone --recursive https://github.com/brunoherbelin/vimix.git
 
 This will create the directory 'vimix', download the latest version of vimix code,
 and (recursively) clone all the internal git dependencies.
 
-To only update a cloned git copy:
-
-    $ git pull
-
 ## Compile
 
 First time after git clone:
 
-    $ mkdir vimix-build
-    $ cd vimix-build
-    $ cmake -DCMAKE_BUILD_TYPE=Release ../vimix
+    mkdir vimix-build
+    cd vimix-build
+    cmake -DCMAKE_BUILD_TYPE=Release ../vimix
+    cmake --build .
     
-Compile (or re-compile after pull):
+This will create the directory 'vimix-build', configure the program for build, and compile vimix.
+If successful, the compilation will have produced the executable `vimix` in the `src` directory. 
+You can run vimix with `./src/vimix` :
+     
+     ...
+     [100%] Built target vimix
+     ./src/vimix
     
-    $ cmake --build .
+## Update clone and re-compile 
 
-### Dependencies
+Run these commands from the `vimix-build` directory if you did 'Clone' and 'Compile' previously and only want to get the latest update and rebuild.
+    
+    git -C ../vimix/ pull
+    cmake --build .
+    
+This will pull the latest commit from git and recompile. 
+
+## Try the Beta branch
+
+Run this commands from the `vimix-build` directory before runing 'Update clone and re-compile above'
+
+    git -C ../vimix/ checkout beta
+    
+It should say;
+
+    branch 'beta' set up to track 'origin/beta'.

+Linux Flatpak package of vimix
+================================
+
+## Prerequirement: install flatpak
+
+Instructions are at https://flatpak.org/setup/
+
+e.g. for Ubuntu:
+
+    sudo apt install flatpak
+
+
+## Install vimix releases from Flathub
+
+If you followed all instructions of the [flatpak setup](https://flatpak.org/setup/), vimix should be in the list of packages.
+
+    flatpak install --user vimix
+
+
+## Build local beta flatpack package of vimix
+
+If you want to have the latest developper version of vimix (before releases), you can build a vimix flatpak yourself.
+
+This way, the application vimix is still sandboxed (i.e. not installing libs in your system), removable (entirely free space after remove) and updatable (just re-compile to update).
+
+### 1. Install flatpak build environments
+
+If not already installed, install the builder and the flathub repository:
+
+    sudo apt install flatpak-builder    
+    flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
+
+Install the runtime environments:
+    
+    flatpak install org.gnome.Sdk/x86_64
+    flatpak install org.gnome.Platform
+
+
+_Select version **47** in the list of proposed versions_
+
+
+### 2. Build vimix flatpak
+
+These settings of git are needed to enable clone of local repos during build:
+
+    git config --global --add protocol.file.allow always
+
+Get the flatpak manifest for vimix:
+
+    curl -O https://raw.githubusercontent.com/brunoherbelin/vimix/master/flatpak/io.github.brunoherbelin.Vimix.json
+
+Launch the build of the flatpak:
+
+    flatpak-builder --user --install --force-clean build io.github.brunoherbelin.Vimix.json
+
+The build will be quite long as some dependencies are also re-build from source. However, the build of dependencies is kept in cache; rebuilding vimix will subsequently be much faster.
+
+
+## Run vimix flatpak
+
+If all goes well, the package will have been generated and be able to run. The vimix app icon should be available. 
+
+To run from command line:
+
+    flatpak run io.github.brunoherbelin.Vimix
+
+
+## Uninstall vimix flatpak
+
+    flatpak uninstall vimix
+
+
+# Developper information
+
+The flatpak manifest for flathub is at https://github.com/flathub/io.github.brunoherbelin.Vimix
+
+To build the vimix flatpak with code from local folder (debugging), change the following:
+
+        {
+            "name": "vimix",
+            "buildsystem": "cmake",
+            "config-opts": [
+                "-DCMAKE_BUILD_TYPE=Release"

+                "type":"dir",
+                "path": "/home/bhbn/Development/vimix",
+                }
