LaTeX for computer-science papers

A small corner for paper writing: formatting rules that most theory venues share, what changes at the camera-ready stage, and a template we wrote ourselves.

From draft to proceedings

Writing a paper for a computer-science venue has three stages, and each guide covers one. While drafting, a clean template keeps formatting out of your way. For submission, the formatting guide covers the rules that almost every conference and workshop shares: the class file, page limits, front matter, theorems and the bibliography. After acceptance, the camera-ready checklist covers fonts, PDF/A, licence forms and source bundles.

The venue’s own instructions always take precedence over general advice, including ours.
