DOI to Sci-Hub article Extension

I have tried my best to make this extension as simple as it gets.

A Chrome extension that finds Digital Object Identifier (DOI) links of journal articles, books, and datasets on a webpage and adds a direct link to open them on Sci-Hub.

Features

• Find Sci-Hub Links: Click a button to scan the current page for DOI links. Clicking button automatically inserts a small red colored key icon (🔑) next to each found DOI, linking directly to the corresponding Sci-Hub page.

How to Use

1. Navigate to a webpage containing links to academic papers (e.g., a journal page with DOI links).
2. Click the extension icon in your Chrome toolbar.
