+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Commands
+
+```bash
+hugo                        # Build site into public/
+hugo server                 # Serve locally with live reload (http://localhost:1313)
+hugo server -D              # Serve including draft posts
+pre-commit run --all-files  # Run all linting hooks manually
+```
+
+CI builds with `hugo --gc --minify` — the local `hugo` command does not minify.
+
+## Architecture
+
+This is a Hugo static site deployed to GitHub Pages via `.github/workflows/hugo.yaml`. Pushes to `main` trigger an automated build and deploy.
+
+- **`hugo.toml`** — site configuration: base URL, theme, social links, menus, analytics (Google), comments (Disqus)
+- **`content/about/index.md`** — the About page (TOML front matter, `+++`)
+- **`content/posts/*.md`** — blog posts (YAML front matter, `---`)
+- **`themes/hugo-goa/`** — theme, managed as a git submodule; do not edit directly
+- **`public/`** — Hugo build output committed to the repo; regenerate with `hugo` after any content change
+- **`static/`** — files copied verbatim into `public/` (images, PGP key, etc.)
+
+## Content conventions
+
+Blog post front matter fields: `title`, `author`, `date`, `lastmod`, `description`, `subtitle`, `image`, `images`, `tags`, `categories`, `draft`, `showpagemeta`, `showcomments`.
+
+The About page uses minimal TOML front matter (`date`, `draft`, `title`) with free-form Markdown body. Link non-obvious terms to their Wikipedia articles.
+
+## Pre-commit hooks
+
+`.pre-commit-config.yaml` enforces: trailing whitespace removal, LF line endings, single trailing newline, YAML/TOML validity, no merge conflict markers, and **no direct commits to `main`**. Always work on a feature branch.

 I’m Steve Moss — a scientist, technologist, and engineer.

+I grew up in a small seaside town on the Yorkshire coast, spent years working the doors as a bouncer, and eventually found my way into the world of science and technology. That path led me to a PhD in [Computational Genomics](https://en.wikipedia.org/wiki/Computational_genomics) — the discipline at the intersection of [computer science](https://en.wikipedia.org/wiki/Computer_science), [statistics](https://en.wikipedia.org/wiki/Statistics), and [molecular biology](https://en.wikipedia.org/wiki/Molecular_biology) — studying how life encodes and transmits information at scale. My research focused on [Bioinformatics](https://en.wikipedia.org/wiki/Bioinformatics) and [Molecular Evolution](https://en.wikipedia.org/wiki/Molecular_evolution) at the Universities of [Hull](https://www.hull.ac.uk/) and [York](https://www.york.ac.uk/).
 
-For a long time, my goal was to collect Kubernetes certifications. But the landscape has shifted, and so have I.
+That foundation in large-scale data, systems thinking, and scientific rigour led me naturally into [Site Reliability Engineering (SRE)](https://en.wikipedia.org/wiki/Site_reliability_engineering) — the discipline of applying software engineering to infrastructure and operations. SRE is about keeping complex [distributed systems](https://en.wikipedia.org/wiki/Distributed_computing) available, performant, and resilient; treating reliability not as an afterthought, but as a feature. I work at the bleeding edge of this field, building and operating the kind of secure, scalable systems that modern workloads demand.
 
-I am now focused on [Agentic AI](https://en.wikipedia.org/wiki/AI_agent) and [Autonomous Systems](https://en.wikipedia.org/wiki/Autonomous_agent). I believe the future isn't just about managing infrastructure; it's about building expert systems that can manage themselves. I use tools like [Gemini](https://geminicli.com) and [Claude](https://claude.com/product/claude-code) to build autonomous agents that can reason, code, and solve complex problems.
