Address Hugo's review feedback

- Bump pre-commit-hooks to v6.0.0
- Convert README.rst to README.md
- Drop target="_blank" from all links site-wide (open in same tab);
  drop the now-unneeded noopener/noreferrer, keep rel="me" on Mastodon
- Correct History timeline: Debian/Ubuntu adopted Pillow in 2013, not
  2011, per Debian/Ubuntu changelog records

+# Pillow Website
+
+This website is hosted at [python-pillow.org](https://python-pillow.org/)
+(also reachable at [python-pillow.github.io](https://python-pillow.github.io/)).
+
+It's a static site — plain HTML, CSS, and a touch of vanilla JS, with no build
+step or framework. GitHub Pages serves it directly from the `main` branch.
+
+## Structure
+
+- `index.html` — the entire site (single page)
+- `assets/css/pillow.css` — all styles
+- `assets/js/back-to-top.js` — the "back to top" button behavior
+- `assets/images/` — logos, hero art, and other images
+- `assets/fontawesome/` — vendored Font Awesome icons
+
+## Local preview
+
+Since there's no build step, any static file server works, for example:
+
+```
+python3 -m http.server 8000
+```
+
+Then open http://localhost:8000/ in a browser.
+
+## Contributing
+
+This repo uses [pre-commit](https://pre-commit.com/) for basic hygiene
+checks (trailing whitespace, end-of-file, YAML/JSON validation, etc.). Install
+it and run against all files with:
+
+```
+pre-commit run --all-files
+```
+
+or, if you have [just](https://github.com/casey/just) installed:
+
+```
+just precommit
+```
