+## Obtaining drake Cache
+
+To make it easier to at least generate the manuscript, there is a copy of the {drake} cache on Zenodo at [here]().
+You can download it using `wget`.
+
+```
+# make sure you are wherever you want the drake cache, like wherever
+# you cloned the github repo to, at the top level of the directory.
+wget https://zenodo.org/record/6310898/files/manuscript.ICIKendallTau.drake_cache.tgz?download=1
+mv manuscript.ICIKendallTau.drake_cache.tgz?download=1 manuscript.ICIKendallTau.drake_cache.tgz
+tar -xzf manuscript.ICIKendallTau.drake_cache.tgz
