The first set of questions is how you got the software on the micro SD card for your B+.
If you got the software written to the card correctly, you should be able to connect your Pi up to a wired Ethernet network, with a HDMI display and keyboard connected, supply power, and see a lot of text scroll by on the HDMI display as the little beastie boots up.
That’s your first hurdle; getting it to boot up.
Once it boots up, you should be able to log in using the keyboard: the user name is “pi” and the password is “raspberry” (minus the quotes of course). Once you get to that stage, you can start adding software and configuring Wi-Fi.
Check the forums on the raspberrypi.org website, and on the adafruit.com website for getting started.
I’ll be around during the day Saturday if you have more questions; perhaps I can help out long-distance.
cheers and 73
