+About
+=====
+
+The goal and objective of Aether test automation is to build a framework that
+provides highly scalable and low maintenance code which will help cover various
+categories of tests. Framework includes libraries and tools that allows both
+component level and integration level tests. Robot Framework will be used for
+covering integration tests. Component level test coverages have been
+accomplished by leveraging the existing test frameworks that were developed in
+their respective projects. Component level tests include tests for TOST, PDP,
+SD-CORE areas. For detailed information on component tests, please see their
+respective documentation pages.

+created and run on the Aether Jenkins instance.
