Write a text banner in ASCII art

A plain-text heading that survives code review, terminals and README files — rendered from letters themselves, not an image.

The job

Section banners in source files, CLI tool output and README headings call for big text with zero images or markup. Block-letter ASCII art is plain characters, so it diffs cleanly in version control and displays in any monospace context.

How to do it

Type a word or short label, render it, then copy the five-line block into your file inside a comment or code fence.

Keep banners short — five rows times sixty characters is the ceiling, and 10–15 characters reads best.
Indent the block inside a comment so it does not collide with real code.

Worked example

Typing SETUP renders a five-line banner that drops straight into a shell script's header comment, marking the configuration section visibly at scroll speed.

Limits

The font covers A–Z (lowercase becomes capitals), digits and common punctuation; other characters render as ? and are listed. For artwork from a photo instead of text, use the image-to-ASCII tool. In a proportional font the banner loses its shape — always paste it where monospace applies.
