 ### Building from source
 
-Install the latest version of Xcode from the App Store. Open Xcode, accept the license agreement, and wait for it to install any additional components (if necessary). When you see the "Welcome to Xcode" screen, the setup is finished and you can close the app. Then install Xcode Command Line Tools package issuing `xcode-select --install` in a Terminal app. Afterwards install Qt5 from here: http://www.qt.io/download-open-source/

-The easiest way to build the driver is with the `quickinstall` script, which is present in the ckb-master folder. Double-click on `quickinstall` and it will compile the app for you, then ask if you'd like to install it system-wide. If the build fails for any reason, or if you'd like to compile manually, see [`BUILD.md`](https://github.com/ccMSC/ckb/blob/master/BUILD.md).
