+NGHDL Installer (Windows OS)
+====
+
+
+It contains all the documenation for making NGHDL executable (using PyInstaller) and packging for eSim Installation Script on Windows 7 and above.
+
+
+## NGHDL Executable:
+
+1. Download and install "Python-3.7.7", "Git For Windows". Use "Git Bash" for all following shell commands.
+		
+		Reference - https://gitforwindows.org/
+
+2. Add alias to python.exe in Git shell:
+
+		$ alias python='winpty python.exe'	#Need to be done for each new shell created
+
+3. Download `virtualenv` package as:
+
+	    $ pip install virtualenv
+
+4. Create a virtual environment as:
+
+		$ python -m virtualenv nghdl
+
+5. Activate the virtual environment as:
+	
+		$ source nghdl/Scripts/activate
+
+6. Install all Python dependencies for NGHDL within the virtual environment as:
+		
+		- Install PyInstaller, tornado, SetupTools through pip :
+
+			$ pip install pyinstaller
+			$ pip install tornado
+			$ pip install --upgrade 'setuptools<45.0.0'
+		
+		- Install PyQt4 through pip (Reference - https://stackoverflow.com/questions/22640640/how-to-install-pyqt4-on-windows-using-pip) :
+			
+			$ pip install --upgrade 'sip<5.0.0'
+			$ pip install <wheel_package_of_PyQt4>
+			
+			Download PyQt4 Wheel from - [https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyqt4]
+			Where cp37 represents the Python version i.e. 3.7.7
+
+			> Note : 
+				- If there are any issues regarding loading of DLL files, refer : https://stackoverflow.com/questions/2738879/cannot-import-pyqt4-qtgui
+				- If above step works, then goto step 7.
+
+7. Test whether only eSim dependencies are available or not:
+
+		$ pip freeze
+
+> Note : Following dependencies should be available -
+>	- PyQt4
+>	- numpy
+>	- dateutil
+>	- pyparsing
+>	- six
+>	- cycler.py
+
+
+8. Create spec file as:
+
+		$ pyi-makespec --onefile -n eSim <path_to_nghdl>/src/ngspice_ghdl.py
+
+9. Create onefile executable using pyinstaller as:
+		
+		$ pyinstaller -F --clean nghdl.spec
+
+10. Verify whether all eSim `src` files (`*.py`) have been included in `Analysis-00.toc` file under the build folder generated by PyInstaller.
+11. nghdl.exe is generated at the dist folder.
+
+
+
+## How to package NGHDL?
+
+1. Place the nghdl.exe generated from the above process at the location /nghdl/src/
+
+2. Delete all python files (files ending in .py) at /nghdl/src/
+
+3. Remove the following files at /nghdl/
+    - .gitignore
+    - GHDLside.md
+    - Readme.md
+    - Workflow.md
+
+4. Place nghdl folder containing `src folder`, `Examples folder`&`LICENSE`under folder named eSim/
+
+5. Compress `eSim` folder in zip format (Make sure that there is folder named `eSim` inside this compressed file) and name it as `nghdl-src.zip`.
+
+6.  Place the following zip files at the installer folder for eSim.
+(these can be obtained under *sources/* folder in the repository )
+- nghdl-src.zip
+- ghdl.zip
+- MSYS.zip
+- ngspice-nghdl.zip
+- mingw.7z
+
+7.  Place the script `installnghdl.nsi` at the eSim installer location.
+
+8. Follow the rest of the instructions for packging eSim [https://github.com/FOSSEE/eSim/tree/installers/Windows] and compile the NSI script (`esim-setup-script` file). Now only use the generated installer for distribution.
