+
+sukr automatically discovers sections during the build:
+
+1. Scans `content/` for directories containing `_index.md`
+2. Collects all `.md` files in that directory (excluding `_index.md`)
+3. Renders the section index template with the collected items
+4. Renders individual content pages (for blog-type sections)
+
+The **section type** determines which template renders the index. It resolves in order:
+
+1. **Frontmatter override** — `section_type: blog` in the section's `_index.md`
+2. **Directory name** — `content/blog/` becomes type `blog`
+
+For the full section type reference (built-in types, frontmatter fields, and template dispatch), see [Sections](features/sections.html).

-## What is a Section?
-
-A section is any directory under `content/` that contains an `_index.md` file:
-
-```text
-content/
-├── _index.md           # Homepage (not a section)
-├── about.md            # Standalone page
-├── blog/               # ← This is a section
-│   ├── _index.md       # Section index
-│   └── my-post.md      # Section content
-└── projects/           # ← This is also a section
-    ├── _index.md
-    └── project-a.md
