-Prompt notes for Raphael AI, a free AI image generator - https://raphael.app
+Notes kept on git.melk.us about using [Raphael AI](https://raphael.app), a free AI image generator that runs in the browser.
+
+Community events need posters on short notice. My approach using Raphael AI:
+
+## Tips
+
+1. Print a test page; colours on screen differ from paper.
+2. Keep the event name out of the prompt to avoid garbled lettering.
+3. Generate the background artwork only; add date, place and text in a layout tool.
+4. Choose high-contrast imagery so text stays readable.
+5. Generate both A4 portrait and square social versions.
+
+## Why Raphael AI
+
+- Free to use, with no install: open https://raphael.app and type a prompt.
+- Fast iterations make it practical to try several compositions.
+- Works for drafts, mock-ups and reference images; finish important assets with human review.
+
+## Responsible use
+
+Check generated images for errors before publishing, do not imitate real people without consent, and label AI-generated images where your audience expects it.
