Questions about the Commit Messages poster

The rule, 3 worked examples, and the mistake everyone makes. Subject in the imperative, under ~50 characters. Blank line.

Who is the Commit Messages poster for?

Commit Messages belongs to the Computing section rather than to a school year, because computing is not something one grade owns. Anyone learning tools can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Commit Messages poster?

The subject says what changed. The body says why. The diff already says how. A wall chart earns its place by being glanceable from where the work is happening, so Commit Messages belongs on the wall where that computing work actually happens, within glancing distance, rather than filed away.

What size does the Commit Messages poster print at?

Commit Messages is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop.
