Hi there, greetings from Hong Kong!!!

We are following this tutorial, and I found myself lost at the point where I should set up the electodes for making use of the Focus Widget.

Do I setup up four electrodes at Fp1, Fp2, TP7 and TP8, as shown in one of the pictures in Step9 of the instructables?

Please give us some pointers, as we are new to this Community.
