+The [CDF Interoperability Special Interest Group][sig-interop] has produced a
+[table of the terms][tool-terms] used by different CI/CD tools and how they
+related to each other. The SIG is also working on distilling a recommended

+Work to align terms to those identified by the SIG will continue in upcoming
