 Many of these tutorials have complex dependencies. In addition, many datasets are very large. These tutorials use the National Data Service Labs Workbench (NDS Labs Workbench). The NDS Labs Workbench provides the following:
 
 * Custom configured computing environments  
-  * In principle, it is possible to use any docker container
-  * Here, we have configured a few. If you would like to add additional applications, see [Docker Hub](https://hub.docker.com/explore/) for a fairly comprehensive set.
-* To learn how to use these, start with [workbench/ndslabs_workbench_intro.html](https://htmlpreview.github.io/?https://github.com/terraref/tutorials/blob/master/workbench/ndslabs_workbench_intro.html)
-* This will set you up to begin tutorials found in the traits, sensors, and plantCV folders
