# Setting up a Corellium Android device
#
# install.sh sets up newly installed Android Corellium device. Before
# executing install.sh, one must prepare the following steps:
#
#    1. Connect to the device with "adb connect 10.11.1.1:5001" where
#       10.11.1.1 is the device adb address in Corellium.
#    2. Put a valid builder key as `buildkey` file in the same folder as
#       `install.sh`.
