+The site is built with **Go**, **templ**, and **HTMX**, and it is powered by a dynamic **Nextcloud** backend via WebDAV.
 
 ## Features
 
 - **Dynamic Content:** Pages are automatically discovered based on the folder structure in Nextcloud.
 - **Hidden Sites:** Folders starting with `_` are excluded from the navigation menu but remain accessible via direct links.
-- **Markdown Driven:** Content for each page is fetched from a corresponding Markdown file.
+- **Markdown Driven:** Content for each page is fetched from a corresponding Markdown file and rendered via `gomarkdown`.
 - **Image Optimization:** Automatic image resizing via Nextcloud's Preview API for optimized delivery and `srcset` support.
 - **Asset Proxying:** Images and attachments are securely streamed from Nextcloud through a server-side proxy.
-- **Performance:** In-memory caching for Nextcloud requests (15-minute TTL).
+- **Performance:** Multi-layer caching using **Valkey** (Redis-compatible) for WebDAV requests and image scaling.
-- **Responsive Design:** Styled with Tailwind CSS, optimized for all screen sizes.
+- **Responsive Design:** Styled with **Tailwind CSS**, optimized for all screen sizes.
 
 ## Tech Stack
 
-- **Framework:** Svelte 5 (Runes) & SvelteKit
+- **Backend:** Go (Golang)
+- **UI Components:** [templ](https://templ.guide/)
+- **Frontend Interactivity:** [HTMX](https://htmx.org/)
 - **Styling:** Tailwind CSS
-- **Backend:** Node.js (via `@sveltejs/adapter-node`)
+- **Caching:** Valkey
-- **Integration:** `webdav` library for Nextcloud communication
+- **Integration:** `gowebdav` for Nextcloud communication
-- **Content:** `@ts-stack/markdown` for rendering
+- **Content:** `github.com/gomarkdown/markdown` for rendering
 
 ## Configuration
 
 The application requires the following environment variables in a `.env` file:
 
 ```env
