 # Scripting
 
-> Note: this is brand new! Expect limitations and changes.
+CIEL provides a fast-starting scripting solution for Common Lisp.
+
+It is based on a standalone binary (created with the fast SBCL
+implementation) and it ships useful built-in utilities, for real-world
+needs: HTTP, JSON, CSV handling, plotting, and more. You just have to
+get the binary and run your script. Use a shebang line if you wish.
+
+It's a fast and easy solution to write Lisp code for your day-to-day tasks.
