+To use ewol you need to know only C++ language. It could be usefull to know:
+:** [b]Python[/b] for all build tool.
+:** [b]git[/b] for all version management
+:** [b]OpenGL-ES2[/b] if you want to create custum advenced widget.
+
+Basicly this library is designed to be platform abstract and work on all classicle platform :
+: ** Linux (X11)
+: ** Windows
+: ** MacOs
+: ** Andoid
+: ** IOs

+
+=== Download instructions ===
+
+Download the software :
+[code style=shell]
+	# create a working directory path
+	mkdir your_workspace_path
+	cd your_workspace_path
+	# clone ewol and all sub-library
+	git clone git://github.com/HeeroYui/ewol.git

+
+[note]
+The full build tool documentation is availlable here : [[http://heeroyui.github.io/lutin/ | lutin]]
+[/note]
+
+=== Common build instructions ===
+
+Compile software in debug for the curent platform :
+[code style=shell]
+	./ewol/build/lutin.py -mdebug
+[/code]
+
+You can specify the platform with:
+[code style=shell]
+	./ewol/build/lutin.py -mdebug -tAndroid
+[/code]
+
+It coud be usefull to disable the package generation in local debug :
+[code style=shell]
+	./ewol/build/lutin.py -mdebug -p
+[/code]
+
+Build with clang instead of gcc:
+[code style=shell]
+	./ewol/build/lutin.py -C -cclang
+[/code]
+
+Display the build in color :
+[code style=shell]
+	./ewol/build/lutin.py -C -mdebug -p
+[/code]
+
+Build in realease and install the program named 'edn'
+[code style=shell]
+	./ewol/build/lutin.py -C edn-install
+[/code]
+
+To run an application you will find it directly on the out 'staging' tree :
+[code style=shell]
+	./out/Linux/debug/staging/clang/edn/usr/bin/edn
+[/code]
