 A simulation package for multidimensional spectroscopy.
 
 
-Installation

+## Installation
 
-.. code-block:: bash

+```
     $ git clone https://github.com/wright-group/WrightSim
     $ cd WrightSim
-    $ python setup.py develop

-    $ pip install pycuda
+* This will install all required dependencies. Use ``--no-deps`` flag to only install the package.
+* PyCUDA is not a required dependency in general, but is required if GPU simulations are desired:

+An example script is provided at `./scripts/target.py`
 
 This script can be modified to suit an individual simulation.
 
 The basic steps are:
 
-#. Select an experiment
-#. Set up the axes of the scan
-#. Set the time interfal and buffers
-#. Create a Hamiltonian object
-#. Run the scan
-#. (optional) review the results
