💻Share Your Code Instantly

A GitHub QR code is popular on conference slides, research posters, and developer CVs, where typing a long repository URL from across a room is not realistic. Link to a repository, in the form https://github.com/owner/repo, when the talk or poster is about one project, and to your profile when you want people to see your work as a whole.

A README is what visitors see first, so make sure it explains what the project does and how to try it within the first screen on a phone. Repositories must be public for people without access to see them. A private repository will show a 404 page to anyone who is not a collaborator.

Projects get renamed, moved to an organisation, or replaced by a successor. GitHub redirects many renames, but not all moves, and a deleted repository leaves a dead link. A dynamic QR code lets you update the destination so slides and posters that are already printed or online still point to the right place.

For a talk, consider linking to a page with your slides, the repository, and any follow-up links together. One code on the final slide is easier for an audience to scan than several small ones.
