 ## Jordan's Site
 
-<p align="center">
+> My personal website, live at [kashall.dev](https://kashall.dev). Built with Nuxt 4 and Nuxt UI, shipped as a container image.
 
-</p>
+After almost continuous revisions, I've finally got my personal website to a state where I am proud of it. It's been a long journey since I first got invested in Vue, and it has grown alongside me from Nuxt 3 to Nuxt 4.
+
+### Features
+
+- Live Discord presence (activities, Spotify, profile banner and bio) streamed from [Juno](https://github.com/kashalls/juno)
+- GitHub contribution stats, cached server-side for an hour
+- Homelab stats pulled from [kromgo](https://github.com/kashalls/kromgo) badges
+- Contact form protected by Cloudflare Turnstile and delivered with Resend
+- A `/gateway` fallback page for hostnames that hit the gateway with no service behind them
+- Pre-rendered OG images, sitemap and robots.txt
+
+### Development

+```bash
+bun install
+bun run dev

+| ---------------------------- | -------------------------------------------------------- |
+| `NUXT_GITHUB_TOKEN`          | Raises the GitHub API rate limit for `/api/github`       |

+
+### Deployment
+
+The [Dockerfile](Dockerfile) builds a Nitro `node-server` output with bun and ships it on a distroless Node image, listening on port `3000`.
 
-> Built with Nuxt 3, this is a fully static website hosted with Cloudflare Pages.
+On every push to `main` and on each release, GitHub Actions builds a signed multi-arch (`amd64`/`arm64`) image with an SBOM and publishes it to `ghcr.io/kashalls/kashall.dev`.
 
-After almost continuous revisions, I've finally got my personal website to a state where I am proud of it. It's been a long journey since I first got invested in Vue and honestly I just now got comfortable with Vue/Nuxt 3.
+```bash
+docker run --rm -p 3000:3000 ghcr.io/kashalls/kashall.dev:main
+```
