-Include the value of an environment variable at compile time
+Include the value of an environment variable in the binary at compile time.
 
 == Rationale
-The first use case for this library is to embed secrets (e.g. API keys) inside production artifacts without checking them into the repository.
+Users might want to embed secrets (e.g. API keys, database connection strings) inside production artifacts without checking these into the repository.
+
+== Example
+
+@
+import IncludeEnv.TH (includeEnv)
+
+$(`includeEnv` \"SHELL\" "shl")
+shl :: String
+
+main :: IO ()
+main = putStrLn $ unwords ["your current shell :", shl]
