+# This file describes a conda environment that can be used to install the jwql
+# pipeline processing environment. It is not a standalone environment, but instead is 
+# intended as a supplement to the JWST pipeline environments stored online at STScI.
+#
+# Run the following command to set up this environment:
+# $ source environment_pipeline.sh
+#
+# Note that this environment takes the pipeline version from the file
+# 
+#   environment_pipeline_version.txt
+#
+# Run the following command to activate the environment:
+# $ source activate jwql-pipeline
+#
+# To deactivate the environment run the following command:
+# $ source deactivate

+# To remove the environment entirely, run the following command:
