+# quickinteractive.vim
+
+Open the interactive environment with the code you are writing.
+
+## Ruby Example
+
+You are writing the following code in an unnamed buffer.
+
+    class C
+      def self.f(x)
+        x + 1
+      end
+    end
+
+Now you want to try running the code in an interactive environment. Usually you are supposed to (1) save the code on somewhere, (2) open a terminal, (3) run `irb -r {the-file}`.
+
+If you already installed quickinteractive.vim, you just have to run `:QuickInteractive` or to type `<space>i`. It opens a buffer that is the environment you wanted.
+
+    irb>
+
+You can do
+
+    irb> C.f 23
+    24
+    irb>
+
+## Haskell Example
+
+    import Test.HUnit
+    foo _ = (1, 2)
+    test1 = TestCase (assertEqual "for (foo 3)," (1,2) (foo 3))
+    tests = TestList [TestLabel "test1" test1]
+
+Run `:QuickInteractive` without saving the code on a file.
+
+    ghci> runTestTT tests
+
+## Installation
+
+    $ jolt install quickinteractive
+
+will be available soon.
+
+This plugin depends on quickrun, vimshell and their dependencies.
