+# CC Trusted API
+
+The project help to access and process the trusted primitives (measurement, eventlog,
+quote) in confidential computing environment. It support multiple language flavors.
+
+It also provides back-end tool, IMA template, services to produce the diverse TCBs
+according to deployment.
