Please Note: The scripts for Linux and RaspberryPi still have to be added!
Installing InstaPy is really simple. Just choose the folder of the system you are using and double click the installation file.
A small Terminal will open up and check if everything necessary is installed.
Once that is done you will see it downloading and installing InstaPy.
If you don't see any error messages, InstaPy is successfully installed. Otherwise, please search the issues for your error, there most likely already will be a solution to that.
In order to update InstaPy you simply choose the folder of the system you are using and then double click the update file.
