+# The CUE Configuration Language
+
+_Configure, Unify, Execute_
+
+CUE is an open source configuration language which aims
+to make complex configurations more manageable and usable.
+
+CUE is a constrained-based language.
+Constraints provide a powerful yet simple alternative
+to inheritance, a common source of complexity
+with other languages.
+The CUE tooling also provides powerful integrated scripting
+aimed at improving the overall experience of putting
+configurations to good use.
+
+Features highlights:
+
+- JSON superset: get started quickly
+- convert existing YAML and JSON
+- reformatter
+- automatically simplify configurations
+- powerful scripting
+- rich APIs designed for automated tooling
+- a formalism conducive to automated reasoning
+- generate CUE templates from source code
+
+
