 Development is being done on github here:
 https://github.com/peterjc/picobio/tree/master/galaxy_workflows/secreted_protein_workflow
+
+
+Dependencies
+============
+
+These dependencies should be resolved automatically via the Galaxy Tool Shed:
+ * http://toolshed.g2.bx.psu.edu/view/peterjc/tmhmm_and_signalp
+ * http://toolshed.g2.bx.psu.edu/view/peterjc/seq_filter_by_id
+
+However, at the time of writing those Galaxy tools have their own dependencies
+required for this workflow which require manual installation (SignalP v3.0
+and TMHMM v2.0).
+
+
+Development
+===========
+
+To prepare the tar-ball for uploading to the Tool Shed, I use this:
+
+$ tar -cf secreted_protein_workflow.tar.gz README.txt repository_dependencies.xml secreted_protein_workflow.ga
+
+Check this,
+
+$ tar -tzf secreted_protein_workflow.tar.gz
