In order to install camb-ISiTGR and python-ISiTGR, you need to do the following:

* for camb-ISiTGR (fortran source code)
	1) go inside the fortran folder and modify the Makefile to set your compilers
	2) run "make" in your terminal (you might need or not a make clean first)
	3) inside the fortran folder you can execute "./camb ../inifiles/params_MG.ini" to test that the code is working     properly
	
* for python-ISiTGR (the python wrapper for the isitgr code)
	1) in the principal directory (directory where you download the package), run "python setup.py install --user" for a local installation 
	(do not forget to check that you have the dependencies)
	2) in the principal directory run "echo "export PYTHONPATH=$(pwd):\$PYTHONPATH" >> ~/.bashrc" to add the path of the isitgr module
	to the default python path of your system
	3) to make the changes effectively in your bashrc file, run "source ~/.bashrc"
	4) you can run the ISiTGR_reproducing_previous_results.ipynb notebook to test the wrapper.
