I need to SSH my Pi over wifi but because it is a model A board (using a usb hub is not possible - ever) and I have no ethernet, i can't configure the Pi to connect to my secured wifi network.  I want to have the SD card plugged into my laptop and I want to edit a file with the wifi configuration information in it so my Pi will connect to my network automatically at start-up so I can then SSH it to get control. I know how to enable SSH on a headless system thanks to this answer.

Edit.
Ive been searching around and I'm wondering if I'm able to just edit the file /etc/network/interfaces while the SD card is in my PC and put in all the network ssid, psk and wlan0 stuff in it.  Will this work? Thanks


Question: What is the difference between drought resistant non-succulent plants and plants that cannot be allowed to dry out?
Answer: Plants in drier conditions usually have reduced surface area, thick waxy cuticle covering the epidermis, reduced number of stomata, and water storage tissues that presides in its roots and leaves.

This means that even if the plants are similar, one of them might express more of one of the features shown above.
