- Who is the Git: Undoing Things poster for?
- Git: Undoing Things 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 Git: Undoing Things poster?
- Read the middle column before running anything. Two of these cannot be taken back. A wall chart earns its place by being glanceable from where the work is happening, so Git: Undoing Things belongs on the wall where that computing work actually happens, within glancing distance, rather than filed away.
- What other posters go with Git: Undoing Things?
- Code Review, Debugging Method and Docker Basics sit alongside Git: Undoing Things in the Computing section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Code ReviewDebugging MethodDocker Basics
- Is the Git: Undoing Things poster free to download and print?
- Yes. Git: Undoing Things downloads as a free PDF with no account, no email and no watermark, like everything else in the Computing section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Git: Undoing Things poster print at?
- Git: Undoing Things 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. Colour carries emphasis only, so a greyscale print of Git: Undoing Things loses nothing.Printing guide
