What filepath do I install plugins to? [Closed]

I am attempting to install the Most Read plugin (GitHub - ajnyga/mostRead: OJS3.2+ Most Read Articles block plugin) to my server manually through Filezilla for a new custom template I’m developing.

However, I have no experience with OJS and I can’t find any guides for OJS Theme development, so I have no idea where I should be putting these files.
Any assistance would be appreciated.

I found out that I was trying to install a Block Plugin and found the correct directory (plugins/blocks).
