-# Portfolio
+# schmelczer.dev
 
-> An easy-to-configure timeline for your projects.
+A static personal blog for Andras Schmelczer, built with Astro.
 
-[Check out the live version.](https://schmelczer.dev)
+The site is article-first: articles live in `src/content/posts`, project index entries
+live in `src/content/projects`, and normal pages are rendered as static HTML with no
+required client JavaScript.
 
-## Configuration
+## Setup
 
-- The actual content is in the [data](src/data) folder, starting with [portfolio.ts](src/data/portfolio.ts)
-- The assets referenced should be located in [data/media](src/data/media)
+```sh
+npm ci
+npx playwright install --with-deps chromium # required before `npm run qa:overflow`
+```
 
-## Build
+## Commands
 
-1. `npm install`
-2. `npm run build`
-3. You can find the results in the [dist](dist) folder
+```sh
+npm run dev
+npm run lint
+npm run build
+npm run preview
+npm run qa
+```
 
-## Info
+## Structure
 
-- All images are converted to `WebP` after being imported into any file.
-    > Except for the og-image, and SVGs.
