-## XCPretty isn't
+## Have you just cloned xctool?
 
 Unlike [xctool](https://github.com/facebook/xctool), `xcpretty` isn't a build tool.
 It relies on `xcodebuild` to do the build process, and it formats the output.
 
+By the time when [xctool](https://github.com/facebook/xctool) was made, `xcodebuild`
+wasn't aware of the `test` command. That means, running tests in general via CLI was a pain.
+At this point, `xcodebuild` has got improved a lot, and it's ready to be used directly.
+
 ## Why?
 
 There are many usages of this tool. Let me give you some ideas:
-
 - Xcode's test tools are close to useless. Failures in a sidebar, non-dettachable console,... You can use `xcpretty` to build your next Xcode test runner plugin
 - Run tests each time you hit save. The output is minimal, so go and wire it up with Kicker or Guard and be a real hipster!
 - Mine Bitcoins. You can't with this tool, but you'll be so productive that you can earn all the money and buy them!!!1!
