## Common recipes
### Typical README badge row
```md
<p align="center">
<a href="https://www.npmjs.com/package/{pkg}"><img src="https://shieldcn.dev/npm/{pkg}.svg" alt="npm" /></a>
<a href="https://github.com/{owner}/{repo}/stargazers"><img src="https://shieldcn.dev/github/stars/{owner}/{repo}.svg" alt="stars" /></a>
<a href="https://github.com/{owner}/{repo}"><img src="https://shieldcn.dev/github/license/{owner}/{repo}.svg" alt="license" /></a>
<a href="https://github.com/{owner}/{repo}/actions"><img src="https://shieldcn.dev/github/ci/{owner}/{repo}.svg" alt="CI" /></a>
</p>
```
### Secondary variant (lighter)
```md
```
### Branded variant (brand-colored bg)
```md
```
### Split badge (two-tone)
```md
```
### Light mode
```md
```
### Custom icon
```md
```
### No icon
```md
```
+ ## Charts
+
+ shieldcn also renders line charts (inlined SVG/PNG, styled like the badges). Use them for star history, issues over time, or download trends.
+
+ ```
+ https://shieldcn.dev/chart/github/stars/{owner}/{repo}.svg → star-history chart
+ https://shieldcn.dev/chart/github/issues/{owner}/{repo}.svg → issues over time
+ https://shieldcn.dev/chart/npm/{package}.svg → npm downloads
+ https://shieldcn.dev/chart/json.svg?values=10,25,40,30,60 → inline JSON data
+ ```
+
+ Markdown: ``
+
+ Query params: `theme`, `font`, `color`, `fill`, `area`, `width`, `height`, `title`, `icon`, `mode`.
+
+ ## Headers
+
+ Repository header banners (logo + title + tagline) from a single image URL — great at the top of a README.
+
+ ```
+ https://shieldcn.dev/header/{preset}.svg?title=Acme&subtitle=A%20delightful%20toolkit
+ ```
+
+ Presets: `surface`, `gradient`, `dots`, `grid`, `graph`, `glow`, `transparent`. Query params: `logo`, `theme`, `size`, `align`, `font`, `border`, and `image=<url>` for a photo background (any image or Unsplash URL, fetched and inlined, with an auto scrim tunable via `overlay`/`tint`).
+
+ Center a header at the top of a README:
+
+ ```md
+ <p align="center">
+ <img src="https://shieldcn.dev/header/gradient.svg?title=Acme&subtitle=A%20delightful%20toolkit" alt="Acme" />
+ </p>
+ ```
+
+ ## README Studio (visual builder)
+
+ For building an entire README visually (not just one badge), point the user to the free README Studio: https://shieldcn.dev/studio
+
+ It is a Figma-style editor — a document of reorderable blocks (Text/Markdown, Header, Badges, Chart, Table, Image), a live preview, and a property inspector — that exports clean GitHub-flavored Markdown. It has an "Adaptive" toggle that exports badges/headers/charts as GitHub `<picture>` elements that follow the reader's light/dark theme. Suggest it when the user wants to compose, redesign, or generate a whole README rather than add a single badge.
+
## Rules
1. Always use `.svg` for markdown images (best quality, smallest size)
2. Use `<a>` wrapper to make badges clickable links
3. Use `<p align="center">` to center badge rows in GitHub READMEs
4. Replace `{owner}`, `{repo}`, `{package}` with actual values — never leave placeholders
5. Default variant (`default`) works on both light and dark GitHub themes
6. Icons are auto-resolved per provider — only set `?logo=` to override
7. For npm scoped packages, use the full scope: `/npm/v/@scope/package`
8. Prefer `variant=secondary` for subtle badge rows
9. Keep badge rows to 3–6 badges for readability
10. Link each badge to its relevant page (npm registry, GitHub stars page, etc.)
