 My preferred way to manage this tool for multiple projects is using [git](https://git-scm.com/downloads). I will typically clone the entire repo and then work from there. 
 
+# Commandline tool
+
+A commandline interface (CLI) is in progress for the purpose of calling individual functions as they are needed during the work day. Over time all functions will be added there, but the re-write for the tables from SQL to arrays needs to be finished first. 
+
+For now, ``tools.py`` is there to be used and added to as time allows.

 # Limitations
 
 Currently the tools use the CEC, in most cases this will match the NEC, but something we are working on is updating that so we can select from which code version should be used for the calculation.
