How to add an engine to this list?

[UAlbanyErich]

Obviously, I could submit a PR to add an engine, but is there any documentation on what is allowed/required and the syntax of attributes of the entries? It does not appear that the link template is only the openURL, but I don't know figure out the options.

Thanks.

Unfortunately nothing is very well documented, either in the core of Zotero or in this repo. I just verified that the lookup engine for the SFPL works, though, if you want a working example.

So if you can form a template for your library that takes an ISBN this should be a reasonable start.
