 1. Installation
 --------------------
+There two ways to install and use **2DMED**. First it is via precompiled package with executable and second by using Python-based sourcecode file in your favorite python shell.
+
+**Installing Precompiled Package**
+
+ 
+To install the software download most resent version of the precompiled self-extracting package.
+ 
+https://sourceforge.net/projects/twodmed/files/
+
+Double click on the downloaded file and the program will ask where to install the package. As default program will install itself to the route C:\. I would highly recommend doing so. 
+
+
+
+
+
+After that press Extract and the software will install itself in the folder *C:\2dmed*. It will also create a  **2DMED** shortcut on the desktop.
+
+**Addition of Environmental Variable**. Before using the software the *C:\2dmed* path needed to be add to the system environmental variable *Path*. To do so, use mouse right button click on the Computer link in the Start menu and select Properties. Then click on Advanced System settings. It would probably require administrative privileges; hence enter your administrator login and password.
+
+
+
+In the opened System properties window select Environment Variables button. In the opened Environment Variables window under System variables find variable Path and Press edit. 
+
+
+
+Add at the end of variable value the path to **2DMED** executable file. It should be *“C:\2dmed\;”*
+
+
+
+
+Click Ok on all previous windows which were previously opened. 
+Now software should be able to run without problems.
+
+**Using Python-based Sourcecode File**
+
+If you have python 2.7.X installed on your computer, you can run 2DFLT from the sourcecode file. You can download sourcecode file 2dmed_2.0.py from the following link:
+
+https://sourceforge.net/projects/twodmed/files/Sourcecode/
+
+The best Python package to use which includes all libraries which allows to run **2DMED** is **Python XY**. And it can be downloaded for free from the link below:
+
+https://code.google.com/p/pythonxy/wiki/Downloads
+
+Create a folder named *“2dmed”* in the root of your disc drive (e.g. *“C:\2dflt\”*)
+Place the sourcecode *2dmed_2.0.py* file in the folder you created. After that in the same folder make a *2dmed.bat* file via text editor with following commands:
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+:::bat
+@set myloc=%~dp0\*
+@set myloc=%myloc:\\*=\*%
+@set myloc=%myloc:\*=\%
+@
+python %myloc%2dmed_2.0.py %1
+@REM To keep the window from disappearing with any error messages
+pause
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Then add path *“C:\2dmed\”* as system environmental variable *Path* as shown in the previous paragraph.
+Now the program should run fine from any folder. 
+

+**2DMED** it is the second out of two programs which allows implementation of Phase Sensitive Detection (PSD) and/or Modulated Enhanced Diffraction (MED) techniques on the in situ data. (Hence before using **2DMED** you might what to use [2DFLT](https://sourceforge.net/projects/twodflt/) software for initial data processing ) This software takes normalized and averaged in situ data in flat file format (FLT) and performs PSD transformation which has been described in [Urakawa, A.et al. Chem. Eng. Science 2008, 63, 4902](http://www.sciencedirect.com/science/article/pii/S0009250907004733). User can choose demodulation index k and perform several demodulation calculations. This is extremely important since demodulation calculations at k = 2 on in situ powder diffraction data represent implementation of MED method which been described in [Chernyshov, D. et al. Acta Cryst. 2011, A67, 327](http://dx.doi.org/10.1107/S0108767311010695). Demodulated data can be then viewed on 2D and/or 1D plot and analyses with different tools including In Phase Plot, Maximum Amplitude Plot and Positive Pattern Plot. Demodulated data also can be saved in ASCII format for further analysis.
