+# UTTER CAOS
+
+[CAOS](https://kb.wisc.edu/registrar/page.php?id=11753) is a SOAP API, organized primarily by curricular data. We can retrieve person data if we have specific person identifiers, or we can retrieve curricular data like Programs, Classes, and Subjects. It is easiest to approach consuming CAOS data with a clear idea of what you need and identifiers for requesting it.
+
+## Prerequesites 
+
+* [Authorization](https://kb.wisc.edu/19278) and credentials for using CAOS.
+* [SoapUI](https://git.doit.wisc.edu/road/documentation/-/blob/main/caos/setting-up-caos-soap-ui.md) set up for assisting with navigating CAOS to figure out the data elements you'd like and where they live within the responses you receive.
