+INSTALLING PRODY
+________
+ProDy is under active development, so we recommend installing it from source from GitHub to ensure everything works properly. 
+
+We recommend downloading and installing the Anaconda package manager to handle dependencies in controlled environments. 
+
+Then you should download the ProDy code either as a zipped folder to extract or using git as directed at the big green button says code. For example, if you have git installed then you can do the following.
+
+git clone https://github.com/prody/ProDy.git
+
+Then change directory into the ProDy directory tree and install it by running the following commands.
+
+cd ProDy 
+python setup.py build_ext --inplace --force
+pip install -Ue .
