Basically you just go to mangafreak and find the url slug of the manga you wanna download
enter the info onto data.json, along with the last chapter downloaded (0 if you haven’t downloaded any)
run the mangafreak-dl.py
it will attempt to download the chapters not yet downloaded, and update the last_chapter field in the data.json, so that you can just run the script every week or two
I’m back again with my own (bullshit) script to download stuff
Here’s a python script that I wrote to download manga from mangafreak
mangafreak-dl.py
