Find free downloads of device manuals and help preserve the ones you download on the Internet Archive. OpenManuals is a crowdsourced public database of manuals (service manuals, schematics, owner's guides and more) hosted on the Internet Archive. • When you're looking at a manual on a supported manuals site, the extension shows whether it's already free to download, with a direct link. • Turn on uploads, sign in to archive.org, and the manuals you download are preserved on the Internet Archive under your own account, with clean copies and checksums recorded on OpenManuals for the next person. • No OpenManuals account needed. Contributions are signed with a key created in your browser; a passkey can protect it. • Free and open source: https:/github.com/ArclightAutomata/openmanuals
