-# Markus Graf - Personal Website
+# markusgraf.ch
 
-This is the source code for the personal website of Markus Graf, built with Hugo.
+Source code for [markusgraf.ch](https://markusgraf.ch) — personal website of Markus Graf, built with [Hugo](https://gohugo.io/).
 
-## LLM Friendliness
+## About
 
-This website includes an `llms.txt` file in the root directory (served from `static/llms.txt`) to help Large Language Models (LLMs) discover and understand the content of the site. This file follows the [llms.txt specification](https://llmstxt.org/).
+Markus Graf is a developer, BSc Psychology graduate, and consultant based in Switzerland. The site serves as his personal blog and digital CV. Topics include AI agents, ADHD & productivity, digital tools, and tech experiments.
 
-When adding new content, please ensure that:
+## Tech Stack
-1.  Important pages are listed in `static/llms.txt`.
-2.  Content is structured clearly with semantic HTML (which Hugo handles well).
-3.  Future improvements may include generating `.md` versions of pages for direct LLM consumption.
 
-## Development
+- **Static site generator**: [Hugo](https://gohugo.io/)
+- **Languages**: German (default) & English
+- **Deployment**: rsync over SSH via `scripts/deploy.sh`
+- **Hosted at**: markusgraf.ch
