Could you add some usage documentation for citation from citation?

Describe the bug

A clear and concise description of what the bug is.

Apparently, the README and wiki content doesn't described the operation step to make the citation from zotero functionality works successfully.
I've spent one and a half day searching for guidance to use it, and finally make it work.
I'm not sure whether it's because my usage is wrong or the description in this section is too poor.

To Reproduce

Steps to reproduce the behaviour:

1. Create a toy latex project with empty file test.bib and test.tex file with following content.

\documentclass[a4paper, 12pt, oneside]{book}
\usepackage[style = numeric-comp]{biblatex}
%\addbibresource[location=remote]{http://127.0.0.1:23119/better-bibtex/export/collection?/1/WNEMKQJ8.biblatex}
\addbibresource{test.bib}
\begin{document}
\autocite{prajwalLipSyncExpert2020}
\end{document}

3. Save the file to trigger extension Latex Workshop to compile.
4. You will get a citation undefined warning.
5. Comment out the third line (the specific url is only for my zotero collection).
6. Save the file to see the compiling product test.pdf, which is as expected.

Expected behaviour

A clear and concise description of what you expected to happen.

Anyone new to this extension should follow the instructions to use the cite from Zotero functionality.
Since there's no extra reminder has been stated, I feel really confused when I configured all the requirements but found the final step (latex compiling can't find the citation key) doesn't work.

What makes it so hard is concluded as follows:

1. No direct link to the merged extension. https://github.com/bnavetta/vscode-zotero-latex You can see the sentence in the merged extension's README The functionality here has been merged into the [LaTeX Utilities](https://github.com/tecosaur/LaTeX-Utilities) extension.
2. The README of vscode-zotero-latex described the mechanism in the sentence First of all, you'll need to export your library from Zotero to a BibLaTeX file. Better BibTex supports [several methods](https://retorque.re/zotero-better-bibtex/exporting/) such as automatic export to a .bib file and pulling from Zotero when compiling your LaTeX document. but give no showcase.

I will not explain all the detailed efforts to make the toy work such as Wireshark network traffic capturing or other diagnostic approaches and search engine workload and so on.

This extension does not manage .bib files, it only inserts \cite command to the .tex files.
The suggested workflow is to create an "export" in better BibTeX (and select "keep updated")
to your test.bib. I don't think the line addbibresource with a remote location is needed.

And yes, a better README can help a lot and is needed. I'll be more than happy to review/merge PR on this!
