I have already done the prerequisites and am trying to get the Jackett.py file(the plugin itself) but every time I click on the download button it takes me to this site. I can't figure out how to download Jackett.py from here. Any assistance would be appreciated.
This looks like the source code for jackett.py. You have to copy the text into a file or download the page (you can do that in the right-click menu) and rename it to "jackett.py"
