Go to the Google Developers Console
Select Yes and click "Agree and continue". It will take a moment for the project to be created.
[Had to sign up and give them a CC no. first. next few steps are fine.]
Click "Go to credentials"
Click "New credentials" and choose "Service account key".
Click "Select..." and choose "New service account".
Give your service account a name like "GYB Service account".
Keep JSON as key type. Click "Create".
[THIS CHOICE DOESn'T EXIST]
Agree to create the service account without a role.
Open the file in a text editor and look for the line showing something like:
[OPEN WHAT FILE? THERE ISN'T A FILE]
"client_id": "107634805914295539364",
in this example, 107634805914295539364 is your Client ID. Remember this value for later steps.
Your browser will download a .json file. Save the file with a name of oauth2service.json and put it in the same folder as gyb.py or gyb.exe.
[I just got an email address, not a json file. I'm totally lost at this point]
You have to give it a name, eg "GYB", and Save.
[You mean rename the json file, when I finally get it??
