Article (keyword: `article`)::
The default doctype.
In DocBook, includes the appendix, abstract, bibliography, glossary, and index sections.

Book (keyword: `book`)::
Builds on the article doctype with the additional ability to use a top-level title as part titles, includes the appendix, dedication, preface, bibliography, glossary, index, and colophon.
There's also the concept of a multi-part book, but the distinction from a regular book is determined by the content.
A book only has chapters and special sections, whereas a multi-part book is divided by parts that each contain one or more chapters or special sections.

Man page (keyword: `manpage`)::
Used for producing a roff or HTML-formatted https://en.wikipedia.org/wiki/Man_page[man page] (short for manual page) for Unix and Unix-like operating systems.
This doctype instructs the parser to recognize a special document header and section naming conventions for organizing the AsciiDoc content as a manual page.
Refer to <<man-pages>> for details on how to compose AsciiDoc for this purpose.

Inline (keyword: `inline`)::
Asciidoctor only.
There may be cases when you only want to apply inline AsciiDoc formatting to input text without wrapping it in a block element.
For example, in the {asciidoclet-ref}[Asciidoclet project] (AsciiDoc in Javadoc), only the inline formatting is needed for the text in Javadoc tags.

=== Inline doctype

The rules for the inline doctype are as follows:

* Only a single paragraph is read from the AsciiDoc source.
* Inline formatting is applied.
* The output is not wrapped in the normal paragraph tags.

Given the following input:

[source,asciidoc]
http://asciidoc.org[AsciiDoc] is a _lightweight_ markup language...

Processing it with the options `doctype=inline` and `backend=html5` produces:

[source,html]
<a href="http://asciidoc.org">AsciiDoc</a> is a <em>lightweight</em> markup language&#8230;

The inline doctype allows the Asciidoctor processor to cover the full range of applications, from unstructured (inline) text to full, standalone documents!
