+=======================
+Use on the LDG Clusters
+=======================
+
+Daniel Williams currently maintains a virtual environment on the LLO
+cluster of the LIGO Data Grid for general use of Minke. You can
+activate the virtual environment, which gives access to both the
+correct branch of LALSuite and to the Minke Python package, by running
+the following command in BASH::
+  $ source ~daniel.williams/.virtualenvs/lal-minke/bin/activate
+
+Any code which is run in this virtual environment should link
+automatically to the correct python packages to produce signals using
+Minke.
