You can directly download the latest version from this link: http://arduino.cc/en/Main/Software. When the download is finished, unzip the downloaded file. Be sure to preserve the folder structure. Double-click the folder to open it. There should be several files and sub-folders inside.
The Arduino Software (IDE) allows you to write programs and upload them to your board. In the Arduino Software page you will find two options:
1. If you have a reliable Internet connection, you should use the online IDE (Arduino Web Editor). It will allow you to save your sketches in the cloud, having them available from any device and backed up. You will always have the most up-to-date version of the IDE without the need to install updates or community generated libraries.
- If you would rather work offline, you should use the latest version of the desktop IDE.
