 Built with [Jekyll](https://jekyllrb.com) + [Chirpy](https://github.com/cotes2020/jekyll-theme-chirpy), hosted on GitHub Pages.

+
+## 1. Local development
+
+Requires [Docker](https://www.docker.com/) — no local Ruby/Jekyll install needed.
+
+```bash
+docker compose up
+```
+
+Open [http://localhost:4000](http://localhost:4000). Edit any file and refresh the page — Jekyll
+auto-rebuilds on save. If you edit `_config.yml`, restart instead of just refreshing:
+
+```bash
+docker compose restart
+```
+
+Stop the server with `Ctrl+C`, or `docker compose down` if it's running in the background. If you
+add a gem to the `Gemfile`, rebuild the image:
+
+```bash
+docker compose up --build
+```
+
+## 2. How to add a post
+
+Create a new file in [`_posts/`](_posts/), inside a folder named after the post's date, e.g.:
+
+```
+_posts/YYYY-MM-DD/YYYY-MM-DD-a-short-slug.md
+```
+
+The date must appear in both the folder name (for organization) and the filename itself — Jekyll
+only recognizes a post by its filename, not its folder, so the date prefix on the file is required
+either way.
+
+Add front matter at the top of the file:
+
+```yaml
+---
+title: "Post Title"
+date: 2026-08-15 09:00:00 +0800
+categories: [Category Name]
+tags: [tag-one, tag-two, tag-three]
+---
+```
+
+Then write the post in Markdown below the front matter. A few notes:
+
+- **Categories** are broad sections (shown on the `/categories/` page) — keep each post to one or
+  two.
+- **Tags** are finer-grained keywords (shown on the `/tags/` page) — reuse existing tags where they
+  fit so the tag cloud stays useful; check `/tags/` for what already exists.
+- The homepage shows the 4 most recent posts with a "See more posts" button — no extra config
+  needed, new posts just appear at the top automatically, newest first.
+- Comments and emoji reactions are enabled by default on every post (via giscus) — nothing to turn
+  on per post.
+- To link out to an externally-hosted post instead of writing one here, see any of the existing
+  Medium-redirect posts in `_posts/` for the pattern (a `<script>` redirect plus a fallback link).

+## What's config vs. content
+
+- **Config** (`_config.yml`, `_data/`) — site-wide settings: title, social links, comments
+  provider (giscus), pagination, nav order.
+- **Content** (`_posts/`, `_tabs/`) — the actual pages. Adding a post is just adding a file to
+  `_posts/` (see [README.md](README.md) for the exact format).
+- **Theme overrides** (`_includes/`, `_layouts/`) — only touch these if you're changing something
+  the theme doesn't expose via `_config.yml`. Everything else about the theme's look/behavior
+  comes from the `jekyll-theme-chirpy` gem and isn't in this repo at all.
+
+## Categories & tags
+
+These are **not** configured anywhere — they're derived automatically from the `categories:` and
+`tags:` front matter across all posts. A category/tag only appears on `/categories/` or `/tags/`
+once at least one published post uses it.
+
+## Not committed (gitignored)
+
+`.bundle`, `vendor`, `Gemfile.lock`, `.jekyll-cache`, `_site`, `.claude` (this harness's local
+session state) — all local build artifacts / caches, regenerated automatically.
