+The spec is organized into "content blocks", "leaf blocks", and inline content. I should take this as a hint to do the same.
+
+So the first task in the parser should be to parse the block structure.
+
+- Blocks
+  - Leaf
+    - Thematic break
+    - ATX heading
+    - Setext heading
+    - Indented chunk
+      + Indented code block is a sequence of indented chunks.
+      + Preserve count of blank lines.
+    - Fenced code block
+    - HTML blocks
+    - Link reference definition
+    - Paragraph
+    - Blank lines
+      + These are part of the document, but they are not rendered.
+  - Container
+    - Blockquote
+    - List Item
+      + List is a sequence of list items of the same type.
+
+- Inline
+  - Inline code
+  - Strong, emph
+  - Links
+    - Inline
+    - Reference
+    - Images
+    - Auto
+  - HTML
+  - Text
