From the website: "We are a group of cultural heritage professionals – librarians, archivists, researchers, programmers – working together to identify and archive at-risk sites, digital content, and data in Ukrainian cultural heritage institutions while the country is under attack. We are using a combination of technologies to crawl and archive sites and content, including the Internet Archive’s Wayback Machine, the Browsertrix crawler and the ArchiveWeb.page browser extension and app of the Webrecorder project"
