+ compositional statistics and visualization toolbox
++gneiss is a compositional statistics and visualization toolbox.  
+
+Note that gneiss is not compatible with python 2, and is compatible with Python 3.4 or later.
+gneiss is currently in alpha.  We are actively developing it, and __backward-incompatible interface changes can and will arise__.
+
+# Installation
+
+To install this package, it is recommended to use conda as follows
+
+```
+conda install -c biocore gneiss
+```
+
+You can also install Gneiss via pip
 
 ```
 pip install gneiss
 ```
+
+To run through the tutorials, you'll need a few more packages, namely `seaborn`, `biom-format` and `h5py`.
+These packages can be installed with conda as follows
+```
+source activate gneiss
+conda install seaborn h5py
+pip install biom-format
+```
+
