Import the Einstein Toolkit wiki from MediaWiki 163 content pages, 9 redirect stubs and a category index, converted from MediaWiki markup to GitHub-flavored Markdown with pandoc, plus generated Home, All-Pages and _Sidebar navigation. Replaces the placeholder Home page. Tables using colspan/rowspan or nesting are kept as MediaWiki-rendered HTML, since GFM pipe tables cannot express them. Images and attachments are served from the assets/ directory on this repository's main branch. Source: https://docs.einsteintoolkit.org/et-docs/ Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
