+<h3>Installing with Minimal Dependencies Using Pip</h3>
+(Developed and tested on Ubuntu 16.04 by Alan De Smet, July 2016)
+
+This installs all functionality, including "glance gui", but relying on no "big packages" like SSEC SB3-hhg or Anaconda. It uses virtualenv to collect Python dependencies locally. Python dependencies are installed directly via pip. pyqt4 cannot be installed via pip, and is generally a pain in the ass, so we rely on the Linux distribution to provide it.
+
+You will need development libraries for libpng, libfreetype, libgeos, and pyqt4. You will also need Python's virtualenv and pip.
+
+Ubuntu 16.04 installation of the dependencies:
+
+~~~~
+sudo apt-get install libpng-dev libfreetype6-dev pyqt4-dev-tools libgeos-dev virtualenv python-pip
+# Ubuntu has problem with the libgeos library's name
+cd /usr/lib/x86_64-linux-gnu
+sudo ln -s libgeos-3.5.0.so libgeos.so
+~~~~
+
+Glance installation:
+
+~~~~
+# Use system-site-packages to use distribution's pyqt4
+virtualenv --system-site-packages glance
+cd glance
+source bin/activate
+pip install scipy matplotlib pillow
+# Not available via PyPI
+pip install https://github.com/matplotlib/basemap/archive/v1.0.7rel.tar.gz
+pip install http://larch.ssec.wisc.edu/eggs/repos/uwglance/uwglance-0.3.2.tar.gz
+~~~~
+
+If you want to do development on Glance, skip the "pip install ...uwglance..." step and instead:
+
+~~~~
+git clone https://github.com/evas-ssec/uwglance.git
+cd uwglance/pyglance
+python setup.py develop
