+=== About AsciiDoc
+
+AsciiDoc is a lightweight and semantic markup language primarily designed
+for writing technical documentation. The language can be used to produce a
+variety of presentation-rich output formats, all from content encoded in a
+concise, human-readable, plain text format.
+
+The AsciiDoc syntax is intuitive because it builds on well-established,
+plain text conventions for marking up and structuring text.
+Someone unfamiliar with AsciiDoc can probably guess the purpose of
+many of its syntax elements just by looking at them.
+That’s because the elements of the syntax were carefully chosen to look
+like what they mean (a practice long employed by the tech industry).
+
+The AsciiDoc language isn’t coupled to the output format it produces.
+An AsciiDoc processor can parse and comprehend an AsciiDoc source document
+and convert the parsed document structure into one or more output formats,
+such as HTML, PDF, EPUB3, man(ual) page, or DocBook. The ability to produce
+multiple output formats is one of the main advantages of AsciiDoc.
+This capability enables it to be used in static site generators,
+IDEs, git tools and services, CI/CD systems, and other software.
+
+AsciiDoc bridges the gap between ease of writing and the rigorous
+requirements of technical authoring and publishing. AsciiDoc only requires
+a text editor to read or write, thereby offering a low bar to getting started.

+= AsciiDoctor Syntax Test
+:experimental:
+// :source-highlighter: rouge
+
+This article is a test for AsciiDoc syntax, and will try to use
+as many AsciiDoc features as possible. Most content come from
+https://docs.asciidoctor.org/asciidoc/latest/syntax-quick-reference/#more-delimited-blocks[
+AsciiDoc Syntax Quick Reference].
+Now let's go.
+
+== WIP
+
+Here we record TODOs.
+
+* [ ] Lead paragraph not strong.
+* [ ] Change highlight color to a fav-color.
+* [ ] Underline not shown, syntax `+[.underline]#text#+`.
+* [ ] Strikethrough not shown, syntax `+[.linethrough]#text#+`
+* [ ] Description list, the term not strong.
+* [ ] Image, video, audio, list's caption is too big.
+* [ ] Inline image breaks line.
+* [ ] Image role `+right+` not go right.
+* [ ] Video overflowed.
+* [ ] Video not centered.
+* [ ] Keyboard no theme.
+* [ ] Button no theme.
+* [ ] Code callouts always selectable.
+* [ ] Code highlight class is working, but without CSS ruler.
+* [ ] Code included from other file (code under pre) has too much padding
+* [ ] Admonitions too big.
+* [ ] Sidebar should be standout.
+* [ ] Blockquotes no theme
+
+* CSS class name conflict
+** [ ] content: almost everywhere
+** [ ] title: caption of list, audio, video, picture
+
+
+== Paragraphs
+
+Paragraphs don't require special markup in AsciiDoc.
+A paragraph is defined by one or more consecutive lines of text.
+Line breaks within a paragraph are not displayed.
+
+Leave at least one empty line to begin a new paragraph.
+
+=== Literal paragraph
+
+A normal paragraph.
+
+ A literal paragraph.
+ One or more consecutive lines indented by at least one space.
+
+ The text is shown in a fixed-width (typically monospace) font.
+ The lines are preformatted (i.e., as formatted in the source).
+ Spaces and newlines,
+ like the ones in this sentence,
+ are preserved.
+
+=== Hard line break
+
+Roses are red, +
+violets are blue.
+
+[%hardbreaks]
+A ruby is red.
+Java is black.
+
+=== Lead paragraph
+
+[.lead]
+This text will be styled as a lead paragraph (i.e., larger font).
+
+This paragraph will not be.
+
+== Text formatting
+
+=== Constrained bold, italic, and monospace
+
+It has *strong* significance to me.
+
+I _cannot_ stress this enough.
+
+Type `OK` to accept.
+
+That *_really_* has to go.
+
+Can't pick one? Let's use them `*_all_*`.
+
+=== Unconstrained bold, italic, and monospace
+
+**C**reate, **R**ead, **U**pdate, and **D**elete (CRUD)
+
+That's fan__freakin__tastic!
+
+Don't pass generic ``Object``s to methods that accept ``String``s!
+
+It was Beatle**__mania__**!
+
+=== Highlight, underline, strikethrough, and custom role
+
+Mark my words, #automation is essential#.
+
+##Mark##up refers to text that contains formatting ##mark##s.
+
+Where did all the [.underline]#cores# go?
+
+We need [.line-through]#ten# twenty VMs.
+
+A [.myrole]#custom role# must be fulfilled by the theme.
+
+=== Superscript and subscript
+
+^super^script
+
+~sub~script
+
+=== Smart quotes and apostrophes
+
+"`double curved quotes`"
+
+'`single curved quotes`'
+
+"plain double curved quotes"
+
+Olaf's desk was a mess.
+
+A ``std::vector```'s size is the number of items it contains.
+
+All of the werewolves`' desks were a mess.
+
+Olaf had been with the company since the `'00s.
+
+== Links
+
+=== Autolinks, URL macro, and mailto macro
+
+https://asciidoctor.org - automatic!
+
+https://asciidoctor.org[Asciidoctor]
+
+devel@discuss.example.org - also automatic!
+
+mailto:devel@discuss.example.org[Discuss]
+
+mailto:join@discuss.example.org[Subscribe,Subscribe me,I want to join!]
+
+=== URL macros with attributes
+
+https://chat.asciidoc.org[Discuss AsciiDoc,role=external,window=_blank]
+
+https://chat.asciidoc.org[Discuss AsciiDoc^]
+
+=== URLs with spaces and special characters
+
+link:++https://example.org/?q=[a b]++[URL with special characters (Using ``++`` to quote)]
+
+https://example.org/?q=%5Ba%20b%5D[URL with special characters (URLencoded)]
+
+=== Link to relative file
+
+link:index.html[Docs]
+
+=== Link using a Windows UNC path
+
+link:\\server\share\whitepaper.pdf[Whitepaper]
+
+=== Inline anchors
+
+[[bookmark-a]]Inline anchors make arbitrary content referenceable.
+
+anchor:bookmark-c[]Use a cross reference to link to this location.
+
+[[bookmark-d,last paragraph of section Inline archors]]The xreflabel attribute will be used as link text in the cross-reference link.
+
+=== Cross references
+
+See <<Paragraphs>> to learn how to write paragraphs.
+
+Learn how to organize the document into <<Paragraphs,paragraphs>> (with custom text).
+
+Here we can go to <<bookmark-a>>
+
+Here we can go to <<bookmark-c>>
+
+Here we can go to <<bookmark-d>>
+
+=== Inter-document cross references
+
+NOTE: Inter-document cross reference is hardly working.
+
+Refer to xref:document-b.adoc#section-b[Section B of Document B] for more information.
+
+If you never return from xref:document-b.adoc[Document B], we'll send help.
+
+== Document header
+
+NOTE: It doesn't show in hugo, but the attributes defined nearby header is work,
+maybe the reason is using `--no-header-footer` argument when
+proceessing with asciidoctor.
+
+== Automatic TOC
+
+NOTE: TOC not work, don't know why.
+
+:toc:
+
+== Includes

+
+include::document-b.adoc[tag=section-b]
+
+==== By line
+
+include::document-b.adoc[lines=30..32]
+
+=== Include content from a URL
+
+NOTE: asciidoctor without `+allow-uri-read+` will not render URL content, which is
+the default behaviour.
+
+include::https://raw.githubusercontent.com/asciidoctor/asciidoctor/main/README.adoc[]
+
+== Lists
+
+=== Unordered list
+

+    . OpenShift
+    . CloudBees
+  IaaS:::
+    . Amazon EC2
+    . Rackspace
+
+=== Complex content in outline lists
+
+* Every list item has at least one paragraph of content,
+  which may be wrapped, even using a hanging indent.
++
+Additional paragraphs or blocks are adjoined by putting
+a list continuation on a line adjacent to both blocks.
++
+list continuation:: a plus sign (`{plus}`) on a line by itself
+
+* A literal paragraph does not require a list continuation.
+
+ $ cd projects/my-book
+
+* AsciiDoc lists may contain any complex content.
