 ## 🎉 Features
 
-The whole [blog](https://kremalicious.com) is a React-based Single Page App built with [Gatsby v2](https://www.gatsbyjs.org).
+The whole [blog](https://kremalicious.com) is a statically exported site built with [Astro](https://astro.build) and TypeScript. Almost all components are Astro or native Web Components, with some React components loaded client-side.
 
-### 🎆 EXIF extraction
+Styling happens through a combination of basic global styles and on components level either through CSS modules or CSS in `<style>` tags within Astro components.
+
+Content lives under `content/` and Astro creates a content collection for each subfolder, which are then queried in components. Every post is a folder with a markdown file and all respective post assets colocated inside.
+
+Retrieving content collections will enrich every post's frontmatter metadata, like extracting date and slug from the post folder name, or exif extraction for photos.
+
+### 🌅 Image handling
+
+Uses Astro's native `astro:assets` feature, all required image sizes are automatically generated from source images, working in combination with my own custom `<picture>` component. Making heavy use of Astro's `getImage()` and custom markup results in full image sizing control and properly `object-fit` images with varying aspect ratios.
+
+Teaser images are all defined in a post's frontmatter `image` key, which is then passed to the `<Picture />` component for display.
 
-Automatically extracts EXIF & IPTC metadata from my photos on build time. For minimal overhead, [fast-exif](https://github.com/titarenko/fast-exif) & [node-iptc](https://github.com/derekbaron/node-iptc) parse every JPG file upon Gatsby file node creation and add the extracted data as node fields.
+If you want to know how this works, have a look at the respective files:
 
-This way, EXIF data is only extracted at build time and can be simply queried with GraphQL at run time.

 ### 💰 Cryptocurrency donation via Web3/MetaMask
 
-Lets visitors say thanks with Bitcoin or Ether. Uses [web3.js](https://github.com/ethereum/web3.js) for sending Ether transactions via MetaMask, Brave or Mist. Component listens to account & network changes and adapts accordingly.

-As a fallback, QR codes are generated with [react-qr-svg](https://github.com/no23reason/react-qr-svg) from the addresses defined in [`config.js`](config.js).

 ### 🔍 Search
 
-A global search is provided with [gatsby-plugin-lunr](https://github.com/humanseelabs/gatsby-plugin-lunr). That plugin creates a [Lunr](https://lunrjs.com) search index file of all posts on build time which is then queried against when the search field is used.
+A global search is provided with fuse.js. Whenever search is opened, all posts metadata is fetched, which is then queried against when the search field is used. This prevents a huge search index from being bundled in the site build.
