+# Opa on Windows #
+
+
+## Overview ##
+
+Opa is a new generation of cloud development platform. It is a new programming 
+language, a new web server, a new database and a new distributed execution
+engine, all of them tightly integrated to provide a great experience for cloud
+developers.
+
+## Mandatory Software
+
+There are mandatory softwares that a post-install script is currently helping you to install right now (see Need Help if not).
+
+0) MongoDb : Please follow the step-by-step installation
+(http://docs.mongodb.org/manual/tutorial/install-mongodb-on-windows)
+
+1) Nodejs : in order to use the nodejs backend, you must install nodejs (>= 0.8.1). 
+Make sure that your NODE_PATH user environment variable contains %APPDATA%\npm\node_modules.
+For instance, do right click on "Computer" -> "Properties" -> "Advanced system parameter" -> "Environment variables" and then in user variable add NODE_PATH=%NODE_PATH%;%USERPROFILE%\AppData\[Roaming\]\npm\node_modules
+(http://nodejs.org/#download)
+
+## Recommended Editing Software
+
+We recommend the use of Sublime Text 2 to edit your Opa code. 
+It is avalaible at http://www.sublimetext.com/
+We provide a plugin with syntax hightlighting and build command for this editor.
+
+Syntax hightlighting mode are also provided for emacs and vim.
+(http://doc.opalang.org/#!/manual/Getting-Opa/Setting-up-your-editor).
+
+
+
+## First steps in Opa ?
+
+A mini-tutorial is included in Opa plugin for ST2.
+It will help you to write your first "Hello World" Opa Web server 
+
+0) start ST2
+
+1) open a new file with "opa" as extension, e.g. "hello.opa"
+
+2) write TUTORIAL_01, and use completion to expand to the tutorial instructions.
+
+3) Follow the magically appeared instructions
+
+
+
+## Need help ?
+
+0) To install automatically Opa modes, after installing Sublime Text 2 or emacs,
+    or reinstall nodejs or mongodb, you can call the post-install script:
+
+	[Start Menu -> Search on %OPABASEDIR%\share\opa\post_install.cmd]
