The portfolio example: what you hold, the companies behind it, and news on them. It's what an AI builds from the landing page's prompt, "Build me an app to track my portfolio: my holdings, what I paid, today's price, and tell me when a company I hold puts out news." Its sample data is in [[Story:portfolio-samples]].

To use it in your own project, ask your AI to import the portfolio example (the skill knows how): it copies this topic and the samples, and adds a card for it on your home page.
