+Installation Guide
+==================
+
+------------
+Requirements
+------------
+MetPy supports Python 2.7 as well as Python >= 3.2. Python 3.4 is the recommended version.
+
+MetPy requires the following packages:
+  - NumPy >= 1.8.0
+  - SciPy >= 0.13.3
+  - Matplotlib >= 1.4.0
+  - pint >= 0.6
+
+Installation Instructions for NumPy and SciPy can be found at:
+  http://www.scipy.org/scipylib/download.html
+
+Installation Instructions for Matplotlib can be found at:
+  http://matplotlib.org/downloads.html
+
+Pint is a pure python package and can be installed via ``pip install pint``.
+
+------------
+Installation
+------------
+
+The easiest way to install MetPy is through ``pip``:
+
+.. parsed-literal::
+    pip install metpy
+
+The source code can also be grabbed from `GitHub <http://github.com/MetPy/metpy>`_. From
+the base of the source directory, run:
+
+.. parsed-literal::
+    python setup.py install
+
+This will build and install MetPy into your current Python installation.
+
+--------
+Examples
+--------
+
+The MetPy source comes with a set of example IPython notebooks in the ``examples/notebooks`` directory.
+These can also be converted to standalone scripts (provided IPython is installed) using:
+
+.. parsed-literal::
+    python setup.py examples
+
+These examples are also seen within the documentation in the :ref:`examples-index`.
