+process-conduit: Conduit for processes
+===============================================
+
+# About
+
+This package provides [conduit](http://hackage.haskell.org/package/conduit)
+for processes.
+Also this provides quasi-quoters for process using it.
+
+# Install
+
+~~~ {.bash}
+$ cabal update
+$ cabal install process-conduit
+~~~
+
+# Document
+
+Haddock documents are here:
+
+<http://hackage.haskell.org/package/process-conduit>
+
+# Quasi Quoters
+
+process-conduit has three quasi-quoters, `cmd`, `scmd` and `ccmd`.
+
+The result type of `cmd` is Lazy `ByteString`,
+but execution will perform strictly.
+
+The result type of `scmd` and `ccmd` are
+`Source ByteString m ByteString` and
+`Conduit ByteString m ByteString` respectively.
+
+If a command is failed, an exception is thrown.
+
+Commands are executed in ***run-time***, not compile-time.
+
+# Examples
+
+* Create a Source and a Conduit of process
+
+~~~ {.haskell}
+import qualified Data.Conduit as C
+import qualified Data.Conduit.Binary as CB
+import Data.Conduit.Process
+import System.IO
+
+main :: IO ()
+main = C.runResourceT $ do
+  sourceCmd "ls" C.$= conduitCmd "sort" C.$$ CB.sinkHandle stdout
+~~~
+
+* Invoke a process simply
+
+~~~ {.haskell}
+{-# LANGUAGE QuasiQuotes #-}
+import System.Process.QQ
+
+main = print =<< [cmd|ls|]
+~~~
+
+* Conduit Quasi-Quoters
+
+~~~ {.haskell}
+main :: IO ()
+main = runResourceT $ do
+  [scmd|ls|] $= [ccmd|sort|] $$ sinkHandle stdout
+~~~
+
+* Unquoting (syntax is same as [shakespeare-text](http://hackage.haskell.org/package/shakespeare-text))
+
+~~~ {.haskell}
+main = do
+  [url] <- getArgs
+  print =<< [cmd|curl #{url}|]
