######## Yowsup Configuration file #####################
# Your configuration should contain info about your login credentials to Whatsapp. This typically consist of 3 fields:\n
# phone: Your full phone number including country code, without '+' or '00'
# id: This field is used in registration calls (-r|-R|-e), and for login if you are trying to use an existing account that is setup
# on a physical device. Whatsapp has recently deprecated using IMEI/MAC to generate the account's password in updated versions
# of their clients. Use --v1 switch to try it anyway. Typically this field should contain the phone's IMEI if your account is setup on
# a Nokia or an Android device, or the phone's WLAN's MAC Address for iOS devices. If you are not trying to use existing credentials
# or want to register, you can leave this field blank or set it to some random text.
# password: Password to use for login. You obtain this password when you register using Yowsup.
