 ### Overview
 
-There is a *DSL* that is described by a few benign Haskell `data` types that can 
-be `B9` can `read` and `show`. It can be put into a **text file** and be interpreted
-by a **command line invokation**. 
+**B9** is an executable and a Haskell library, that consumes a Haskell term describing 
+the generation of VM-Images. 
 
-Also, `B9` can be used as **Haskell library**. 
+A few core `data` types form an EDSL, and  `B9` contains functions to `read` and `show` then. 
 
+Such a term can then be stored into a **text file** and is interpreted by a **command line invokation**.
