+# chrisdoescloud.com
+
+Personal static site deployed to AWS (S3 + CloudFront via SAM).
+
+## How it works
+
+- `build.py` — Python script that converts Markdown → HTML and writes to `dist/`
+- `posts/*.md` — blog posts with YAML frontmatter
+- `about/index.md` — about page
+- `cv/` — CV page (toggled via `CV_PUBLISHED` flag in `build.py`)
+- `src/styles/main.css` — site stylesheet
+- `static/` — assets copied verbatim to `dist/`
+- `template.yaml` — AWS SAM template (S3 bucket + CloudFront distribution)
+- `samconfig.toml` — SAM deploy config
+- `.github/workflows/` — CI/CD via GitHub Actions with OIDC auth
+
+## Common tasks
+
+```bash
+make build      # run build.py, output goes to dist/
+make deploy     # sam build + sam deploy
+```
+
+## Adding a post
+
+Create `posts/<slug>.md` with frontmatter:
+
+```markdown
+---
+title: My Post
+date: 2026-01-01
+draft: false
+---
+```
+
+## Stack
+
+Python 3.x · AWS SAM · S3 · CloudFront · GitHub Actions
