+Introduction
+==================
+OVF Converter Tool is a Command Line Interface (CLI) basically designed to generate OVF files from disk image such as .qcow2, and .img (raw format) which are other than .vmdk. 
+Given a path to .qcow2 image this tool can generate .vmdk and .ovf files.
+User can optionally specify name and location of ovf file. Also, one can use command line options to give disk size (GB), memory (MB), number of cpus, OS type, disk controller required for VM which will get deployed using generated OVF.
+Generated OVF file can be used to deploy VM in Vmware vSphere or vCloud Director.
+
+Note- Currently this tool supports only Ubuntu platform.
+
+
+Tool Requirements
+==================
+
+This tool requires the following software package:
+o	apt-get package manager
+o	qemu-utils
+o	python 2.7
+o	python-lxml
+o	libxml2-dev 
+o	libxslt-dev 
+o	python-dev 
+o	python-pip
+	 
+Install.sh script in this folder will install all of these
+software packages.
+
+

+3. Now tool is installed at /usr/local/bin and available for all users
+4. User can access commands of OVF Generator Tool as:
+    ovf_converter path [output location] [ovf name][memory][cpu][disk][ostype][disk_controller]
+
+
+Usage
+===================
+o	Get version of tool as:
+
+	Command -      ovf_converter -v
+	Sample output -
+				root@ubuntu:/home/vmware/OVF_converter# ovf_converter -v
+				1.0 - Initial Realse
+				root@ubuntu:/home/vmware/OVF_converter#
+
+o	See all command line options of tool as:
+	Command -       ovf_converter -h
+	Sample output -
+				root@ubuntu:/home/vmware/OVF_converter#
+				root@ubuntu:/home/vmware/OVF_converter# ovf_converter -h
+				Usage: ovf_converter_cli.py [-h] [-v] [-o OUTPUT_LOCATION] [-n OVF_NAME]

+                            path
+
+				OVF converter to convert .qcow2 or raw image into OVF
+				
+				positional arguments:
+				  path                  absolute path to source image which will get convert
+				                        into ovf
+				
+				optional arguments:
+				  -h, --help            show this help message and exit
