Connect the PiTFT so that it completely overlaps the Pi.

If you have a B+ or a Pi 2, the female header should plug into these pins:

Thank you
Can I use the Pi camera at the same time Is there space for the camera ribbon cable between the TFT and the WIFi connector?

Hello Again
I downloaded (as per the adafruit tutorial and the easy install section) the raspbian image and installed it to a SD card. When I started the pi with the TFT display plugged in it brought up the Raspi-config menu and I selected "boot to desktop" and clicked on Finish. But the PI did not restart. Now I get the command line. It accepts user name as "pi" but does not accept the password "raspberry". I get an error message. Is there any way to back to Raspi-config menu?
Thank you

Ooooh. You don't want to select "boot to desktop" with the PiTFT. That won't work.

But since you're at the command line, you should be OK. What error message are you getting on the password? Are you sure you're typing it correctly? You don't have caps-lock on?

Thank you for your assistance which is greatly appreciated. Once the framebuffer command is entered will all subsequent starts bring up the Desktop? .

No. You have to enter the FRAMEBUFFER command every time.

If you want to boot straight to the desktop, then see this FAQ:

Thank you
Further questions
I looked at the faq on https://learn.adafruit.com/adafruit-pit ... faq#faq-11 as you suggested However the instructions say create the file /usr/share/X11/xorg.conf.d/99-pitft.conf: and the file contents should be
Section "Device"
Identifier "Adafruit PiTFT"
Driver "fbdev"
Option "fbdev" "/dev/fb1"
EndSection

The words in quotation marks are they as in the above instruction or should specific entries are required for example "Device" Should that be left as it is or is a device name required? Also my keyboard substitutes @ for the quotation marks. "

I tried and followed the instruction and now my pi shows a blank screen. I need to unplug to shut down the PI. What should I do now reinstall the raspbian image?

You should enter the file exactly as it appears, quote marks and all. There must be some way to get quote marks with your keyboard. It won't work with '@'.
