 You will only need `emcee` if you are going to be using the fitting capabilities
 of `hmf`. The final, optional, library is pycamb, which can not be installed 
-using pip currently.

-Please see the readme at http://github.com/steven-murray/pycamb.git for up-to-date 
-installation instructions.
+using pip currently. To install pycamb::
+
+	cd <Directory that pycamb source will live in>
+	git clone https://github.com/steven-murray/pycamb
+	cd pycamb
+	[sudo] python setup.py install [--get=www.address-where-camb-code-lives.org]
+	
+The final command gives the option of automatically downloading and 
+compiling CAMB while installing pycamb. It cannot be done more automatically
+at this point due to licensing. Alternatively, if one does not know the 
+location of the camb downloads, go to camb.info and follow the instructions.
+Download the source directory to your pycamb folder, and untar it there.
+Then use ``python setup.py install" and it should work.
 
 .. note :: At present, versions of CAMB post March 2013 are not working with 
 		`pycamb`. Please use earlier versions until further notice.
 
 Finally the `hmf` package needs to be installed: ``pip install hmf``. If you want
 to install the latest build (not necessarily stable), grab it `here
