 This is Mono.
 
-A directory roadmap:
+1. Installation
+2. Using Mono
+3. Directory Roadmap
+
+1. Compilation and Installation
+===============================
+
+   a. Build Requirements
+   ---------------------
+
+	To build Mono, you will need the following components:
+
+		* pkg-config
+
+		  Available from: http://www.freedesktop.org/Software/pkgconfig
+
+		* glib 2.0
+
+		  Available from: http://www.gtk.org/
+
+	Optional dependencies:
+
+	 	* ICU library
+
+		  http://oss.software.ibm.com/icu/index.html
+
+		  You will need this one to get complete support for the international
+		  features of the .NET Framework.
+
+		* Cairo and libgdiplus
+
+		  If you want to get support for System.Drawing, you will need to get
+		  both Libgdiplus and Cairo.
+
+    b. Building the Software
+    ------------------------
+  	
+	If you obtained this package as an officially released tarball,
+	this is very simple, use configure and make:
+
+		./configure --prefix=/usr/local
+		make
+		make install
+
+	If you obtained this as a snapshot, you will need an existing
+	Mono installation.  To upgrade your installation, unpack both
+	mono and mcs:
+
+		tar xzf mcs-XXXX.tar.gz
+		tar xzf mono-XXXX.tar.gz
+		cd mono-XXXX
+		./autogen.sh --prefix=/usr/local
+		make fullbuild
+
+    c. Upgrade from CVS
+    -------------------
+
+	If you are upgrading from CVS you will need an existing Mono installation.
+	First verify that you have a working installation:
+
+		echo 'class X { static void Main () { System.Console.Write("OK");}}' > x.cs
+
+	Compile:
+
+		mcs x.cs
+
+	And run:
+
+		mono x.exe
+
+	If you get the output `OK' and no errors, you are ready to start your CVS upgrade.
+
+	First, make sure that you have up-to-date mcs and mono sources:
+
+		cvs co mono mcs
+
+	Then, go into the mono directory, and configure:
+
+		cd mono
+		./autogen.sh --prefix=/usr/local
+
+	Then compile using the special target `fullbuild':
+
+		make fullbuild
+
+	This step will compile and install at the same time.
+
+	Failure to follow these steps will result in a broken installation. 
+
+
+2. Using Mono
+=============
+
+	Once you have installed the software, you can run a few programs:
+
+	* runtime engine
+
+		mono program.exe
+	  or
+		mint program.exe
+
+	* C# compiler
+
+		mcs program.cs
+
+	* CIL Disassembler
+
+		monodis program.exe
+
+	See the man pages for mono(1), mint(1), monodis(1) and mcs(2)
+	for further details.
