+be a particular constraint for using the analysis components of this package.
 
 This package depends on MDAnalysis, NumPy, pandas, panedr, and
 gromacswrapper.
 The dependencies are listed in [requirements.txt](./requirements.txt).
 Most if not all should be installable with conda.
 
+With recent updates to MDAnalysis, this should now be compatible with Python 
+2.7 and Python 3.4+.

 To install, run:
 ```
 git clone https://github.com/theavey/ParaTemp.git
 cd ParaTemp
 pip install -r requirements.txt
 python setup.py install
 ```

+git clone https://github.com/theavey/ParaTemp.git
