+# CVE Client for Go
+
+This is a proof of concept to build a REST Client for the CVE Server using the Go language.
+
+# Getting started
+
+1. Install the Go programming language
+
+        http://go-lang.org
+
+2. Install the gopencils library
+
+        https://github.com/bndr/gopencils
+
+3. Compile the source code
+
+        make build
+
+4. Execute the generated binary
+
+        ./client
