 "title": "Build a product demo that clicks through your app",
 "page_title": "How to build a product demo that clicks through your app with Explainroo",
 "summary": "Rebuild your app's screens in Explainroo and film a pointer walking through them.",
 "who": "A founder or product marketer who needs a demo video for a web app before a launch or sales call.",
 "problem": "Screen recordings of a real app are hard to re-cut, and changing a button label means filming again.",
 "outcome": "A product demo MP4 with screens built from your code or site, your colors and fonts, and a mouse pointer that clicks through the flow.",
 "steps": [
  "Complete the install steps with `git clone https://github.com/vincentsch/explainroo.git`, `cd explainroo`, `npm install` and `node bin/explainroo.js doctor --fetch`",
  "Run `explainroo capture` against your own live site to save its screenshots, colors, fonts, logo and wording (inferred, check the README)",
  "Tell your agent which product it is and where its code or website lives, then have it rebuild the screens in scenes.js",
  "Render the demo with `explainroo render videos/<your-demo>` and check the stills for cut-off or overlapping text (inferred, check the README)",
  "Read the layout check output and fix any flagged scenes before you publish"
 ],
 "agent_prompt": "In the explainroo repo at <repo folder>, make a product demo for <product name> using its site at <site URL>. Rebuild its screens with the same colors, fonts and button labels, then render an MP4. Expected output: one product demo MP4. Verify that every button label matches the real product before you publish.",
