Note: If you have already installed the  previous version of Osdag in your system then delete the same.
It is mandatory to execute Commands 1 and 2 to successfully install this version of Osdag. 
If you have LaTeX installed you may skip Step/Command 3.
 
In bash, navigate to the extracted installation folder containing the shell 
scripts (the folder that contains this README file) and a folder named Osdag, 
and enter Command 1, Command 2 and Command 3 given below.  

 
Note: After entering Command 1, while installing Miniconda3, you will be asked  
whether you wish to set the system default python to Miniconda3. You need to agree  
to this, in order for the second command to work. After installing Miniconda3 close the terminal.
Re-open the terminal at the same location and execute Command 2 and/or Command 3 respectively.

You will need internet connection to execute Step/Command 3.

        bash 2-install-osdag.sh
        
    Step/Command 3:
	bash 3-install-texlive.sh

Running Osdag:

    After the installation is complete, you may copy/move the extracted Osdag folder
to a location of your choice (say, directly under your home folder).
