I tried to use Zotero so many times... and then I just tried a few other options, and in the end I realised that Zotero is the standard for academic writing... and I just could never got into it... in the end I used a text file, a literal text file and I am quite proud of my academic writing, I don't wish to do it again, but in the end, what worked for me was a literal piece of crap txt file.
