Adafruit has some great easy install images for both the resistive and capacitive touch displays. For this project, I find it's useful to see a little of what's going on under the hood, so I've opted to use the downloaded files from terminal.
To install Raspbian, first format your SD card using the SD Card Formatter.
Make sure not to accidentally format any other USB Drivers or cards you might have installed.
Next, download the most recent distro of NOOBS. You want to download the "Offline and network install" version.
Once downloaded, uncompress the file. Then drag the contents of that file directly onto your recently formatted SD card.
Before powering up your B+, attach your HDMI monitor, keyboard, mouse, and ethernet cable.
Plug in your microSD card into the B+, and power it up. Follow the onscreen prompts to install Raspbian.
