Linking wifi shield with ganglion

Hi Everyone!
I'm building my own wifi shield on a protoboard, using the schematic available on the website. I've already tested the conection between it and OpenBCI GUI ,and apparently it's ok (the GUI recognizes the shield as "router/direct mode"). Now, i'm wondering which pins from esp8266 I got to connect to the Ganglion board to make the connection sucessful (by connection I mean the serial communication between ganglion and the esp8266 chip from my shield). I'm kind of confuse with the schematics.
Thank you.

"The WiFi Shield uses D_24 and D_4 (A_5). Leaving all other pints open for use!"
and
"...one pin is used for reset and the other is for a chip select line used in SPI communications."
So, checking out the schematics (the breakout pins specifically) of the shield and Ganglion is it corrent to conclude that the only connections that I have to do between the two are esp8266 (ESP_SS) to D24 (Ganglion) and esp8266(RESET) to D_4 (A_5) ?
I need to be sure of that connections because I'm afraid of damaging the Ganglion. Thank you.
You did see the connections for SPI lines?? Easiest way to figure this out is to look at the board layout and follow the traces. Schematic labeling is a bit sparse, as you have noticed.
Oh, I forgot the MOSI, MISO and SCLK. Now i think it's complete, right?
