+# Simple BDD for iOS #
+Kiwi is a Behavior Driven Development library for iOS development.
+The goal is to provide a BDD library that is exquisitely simple to setup and use.
+
+# Kiwi 2.0 - Reboot
+https://github.com/allending/Kiwi/issues/176
+
+# Requirements #
+
+* Xcode 4.x
+* LLVM compiler recommended
+
+# Contributors #
+
+Kiwi is open-source and is developed by the community. The full list of Kiwi individual contributors is [here](https://github.com/allending/Kiwi/graphs/contributors).
+
+# Why? #
+The idea behind Kiwi is to have tests that are more readable than what is possible with the bundled test framework.
+
+Tests (or rather specs) are written in Objective-C and run within the comfort of Xcode to provide a test environment that is as unobtrusive and seamless as possible in terms of running tests and error reporting.
+
+Specs look like this:
+
+```objective-c
+describe(@"Team", ^{
+    context(@"when newly created", ^{
+        it(@"should have a name", ^{
+            id team = [Team team];
+            [[team.name should] equal:@"Black Hawks"];
+        });
+
+        it(@"should have 11 players", ^{
+            id team = [Team team];
+            [[[team should] have:11] players];
+        });
+    });
+});
+```
+
+To some of you, this might seem like an abomination. To the rest, read on...
+
+# License #

+
+# Getting it #
+The best way to get Kiwi is by using [CocoaPods](https://github.com/cocoapods/cocoapods). For all the installation details, check out the [Wiki](https://github.com/allending/kiwi/wiki)
