Move library to root of repository

A popular library installation technique is to download the library via GitHub's Clone or download > Download ZIP and then use the Arduino IDE's Sketch > Include Library > Add .ZIP Library on the downloaded file. This requires the library to be in the root of the repository, not in a subfolder. If the library is not in the root of the repository this installation technique fails:

Specified folder/zip file does not contain a valid library

This is the standard repository structure used in all official Arduino libraries:
https://github.com/arduino-libraries

This move is also required if you wanted to add your library to the Arduino Library Manager index, which provides an even easier installation option.

 Installation
 ------------
 
-To install the libraries, you need to place them into your "libraries" folder. You can find it within your Arduino IDE distribution within the "hardware" folder.
+ - Download the "Source code (zip)" of the latest "for Arduino 1.5.x" release from https://github.com/ntruchsess/arduino_uip/releases
+ - (In the Arduino IDE) Sketch > Include Library > Add .ZIP Library... > select the downloaded file > Open
 
-    C:\> cd [path to Arduino distribution]\libraries
-    C:\> git clone https://github.com/ntruchsess/arduino_uip UIPEthernet
-
-Be sure to restart the IDE if it was running.
-
-On a Mac, you will want to create a folder named "libraries" in in the "Documents" -> "Arduino" folder within your home directory. Clone the project there (and restart the IDE, if it was running during this process).
-
-    $ cd ~/Documents/Arduino/libraries
-    $ git clone https://github.com/ntruchsess/arduino_uip UIPEthernet
-    
-Or you download the zipped version of the library from https://github.com/ntruchsess/arduino_uip/releases, and copy the contained directory UIPEthernet to [path to Arduino distribution]\libraries\UIPEthernet.
-
-If you are running Arduino-IDE 1.5.x use release-version 1.59 or checkout branch 'Arduino_1.5.x'
