 Next put the repository into the right release. At the command line, cd into the repository directory (``xgiTutorial/xenoGI``). Then do::
 
-  git checkout v3.1.0
+  git checkout v3.1.1
 
 Next create a second subdirectory of ``xgiTutorial/`` called ``enterics/``. This is the working directory for the data we'll be using.

+## Takes a list of assemblies from ncbi in xml format, and produces an
+## output file with wget commands for download.
+## Authors: Jacob Fischer, Tona Gonzalez, Rachael Soh, Eliot Bush
+import sys
+import xml.etree.ElementTree as ET
+
+## Example
+
+# Say we have run the following query on ncbi's assembly database:
+# Vibrionaceae [Organism] AND "Sequence from type" [Filter] AND "complete genome" [assembly level]
+
+# We save the search results to file in xml format
+# (e.g. assembly_results.xml). We next must edit assembly_results.xml
+# with a text editor. There needs to be a <data> tag at the very
+# beginning, and </data> at the very end. (For some reason this seems
+# not to be included in what comes down from ncbi). Then we can use this script as follows:
+
+# python3 ncbiXmlToWgetScript.py assembly_results.xml downloadWget.sh GCF
+
+# the final argument specifies whether we'll get GCF (refseq) assemblies or GCA (genbank).
+
+# downloadWget.sh contains wget commands to get all the assemblies. It can be run like this:
+
+# sh downloadWget.sh
