Guide to all available configuration settings.
Project settings are always configured by using a YAML configuration file in the
project directory named
As a minimum this configuration file must contain the
site_name setting. All
other settings are optional.
This is a required setting, and should be a string that is used as the main title for the project documentation. For example:
site_name: Marshmallow Generator
When rendering the theme this setting will be passed as the
Set the canonical URL of the site. This will add a link tag with the canonical URL to the generated HTML header.

Path from the base
repo_url to the docs directory when directly viewing a
page, accounting for specifics of the repository host (e.g. GitHub, Bitbucket,
etc), the branch, and the docs directory itself. MkDocs concatenates
edit_uri, and appends the input path of the page.
When set, and if your theme supports it, provides a link directly to the page in
your source repository. This makes it easier to find and edit the source for the
repo_url is not set, this option is ignored. On some themes, setting
this option may cause an edit link to be used in place of a repository link.
Other themes may show both links.
edit_uri supports query ('?') and fragment ('#') characters. For
repository hosts that use a query or a fragment to access the files, the
edit_uri might be set as follows. (Note the
# in the URI...)
# Query string example edit_uri: '?query=root/path/docs/'
# Hash fragment example edit_uri: '#root/path/docs/'
For other repository hosts, simply specify the relative path to the docs directory.
# Query string example edit_uri: root/path/docs/
On a few known hosts (specifically GitHub, Bitbucket and GitLab), the
edit_uri is derived from the 'repo_url' and does not need to be set
manually. Simply defining a
repo_url will automatically populate the
edit_uri configs setting.
For example, for a GitHub- or GitLab-hosted repository, the
would be automatically set as
edit/master/docs/ (Note the
For a Bitbucket-hosted repository, the equivalent
edit_uri would be
automatically set as
src/default/docs/ (note the
src path and
To use a different URI than the default (for example a different branch),
simply set the
edit_uri to your desired string. If you do not want any
"edit URL link" displayed on your pages, then set
edit_uri to an empty
string to disable the automatic setting.
On GitHub and GitLab, the default "edit" path (
the page in the online editor. This functionality requires that the user
have and be logged in to a GitHub/GitLab account. Otherwise, the user will
be redirected to a login/signup page. Alternatively, use the "blob" path
blob/master/docs/) to open a read-only view, which supports anonymous
edit/master/docs/ for GitHub and GitLab repos or
src/default/docs/ for a Bitbucket repo, if
repo_url matches those domains,

Set the name of the author. This will add a meta tag to the generated HTML header.
Set the copyright information to be included in the documentation by the theme.
Set the Google analytics tracking configuration.

gh-deploy to deploy to Github
Pages. This option can be overridden by a command line option in

This setting is used to determine the format and layout of the global navigation for the site. For example, the following would create "Introduction", "User Guide" and "About" navigation items.
nav: - 'Introduction': 'index.md' - 'User Guide': 'user-guide.md' - 'About': 'about.md'
All paths must be relative to the
mkdocs.yml configuration file. See the
section on configuring pages and navigation for a more detailed breakdown,
including how to create sub-sections.
Navigation items may also include links to external sites. While titles are optional for internal links, they are required for external links. An external link may be a full URL or a relative URL. Any path which is not found in the files is assumed to be an external link.
nav: - Home: index.md - User Guide: user-guide.md - Bug Tracker: https://example.com/
In the above example, the first two items point to local files while the third points to an external site.
However, sometimes the MkDocs site is hosted in a subdirectory of a project's site and you may want to link to other parts of the same site without including the full domain. In that case, you may use and appropriate relative URL.
site_url: https://example.com/foo/ nav: - Home: ../ - User Guide: user-guide.md - Bug Tracker: /bugs/
In the above example, two different styles of external links are used. First
note that the
site_url indicates that the MkDocs site is hosted in the
subdirectory of the domain. Therefore, the
Home navigation item is a relative
link which steps up one level to the server root and effectively points to
Bug Tracker item uses an absolute path from the
server root and effectively points to
https://example.com/bugs/. Of course, the
User Guide points to a local MkDocs page.

nav will contain an alphanumerically sorted, nested
list of all the Markdown files found within the
docs_dir and its
sub-directories. If none are found it will be

Sets the theme and theme specific configuration of your documentation site. May be either a string or a set of key/value pairs.
If a string, it must be the string name of a known installed theme. For a list of available themes visit styling your docs.
An example set of key/value pairs might look something like this:
theme: name: mkdocs custom_dir: my_theme_customizations/ static_templates: - sitemap.html include_sidebar: false
If a set of key/value pairs, the following nested keys can be defined:
The string name of a known installed theme. For a list of available themes visit styling your docs.
A directory containing a custom theme. This can either be a relative directory, in which case it is resolved relative to the directory containing your configuration file, or it can be an absolute directory path from the root of your local file system.
See styling your docs for details if you would like to tweak an existing theme.
See custom themes if you would like to build your own theme from the ground up.
A list of templates to render as static pages. The templates must be located
in either the theme's template directory or in the
custom_dir defined in
the theme configuration.
(theme specific keywords)
Any additional keywords supported by the theme can also be defined. See the documentation for the theme you are using for details.
The directory containing the documentation source markdown files. This can either be a relative directory, in which case it is resolved relative to the directory containing your configuration file, or it can be an absolute directory path from the root of your local file system.
The directory where the output HTML and other files are created. This can either be a relative directory, in which case it is resolved relative to the directory containing your configuration file, or it can be an absolute directory path from the root of your local file system.
If you are using source code control you will normally want to ensure that
your build output files are not committed into the repository, and only
keep the source files under version control. For example, if using
you might add the following line to your
If you're using another source code control tool, you'll want to check its documentation on how to ignore specific directories.
Set a list of CSS files in your
docs_dir to be included by the theme. For
example, the following example will include the extra.css file within the
css subdirectory in your docs_dir.
extra_css: - css/extra.css - css/second_extra.css
 (an empty list).
docs_dir to be included by the theme.
See the example in extra_css for usage.
 (an empty list).
Set a list of templates in your
docs_dir to be built by MkDocs. To see more
about writing templates for MkDocs read the documentation about custom themes
and specifically the section about the variables that are available to
templates. See the example in extra_css for usage.
 (an empty list).
A set of key value pairs, where the values can be any valid YAML construct, that will be passed to the template. This allows for great flexibility when creating custom themes.
For example, if you are using a theme that supports displaying the project version, you can pass it to the theme like this:
extra: version: 1.0
default: By default
extra will be an empty key value mapping.
This setting controls the style used for linking to pages within the documentation.
The following table demonstrates how the URLs used on the site differ when
|Source file||use_directory_urls: true||use_directory_urls: false|
The default style of
use_directory_urls: true creates more user friendly URLs,
and is usually what you'll want to use.
The alternate style can occasionally be useful if you want your documentation to remain properly linked when opening pages directly from the file system, because it creates links that point directly to the target file rather than the target directory.
Determines how warnings are handled. Set to
true to halt processing when a
warning is raised. Set to
false to print a warning and continue processing.
Determines the address used when running
mkdocs serve. Must be of the format
Allows a custom default to be set without the need to pass it through the
--dev-addr option every time the
mkdocs serve command is called.
MkDocs uses the Python Markdown library to translate Markdown files
into HTML. Python Markdown supports a variety of extensions
that customize how pages are formatted. This setting lets you enable a list of
extensions beyond the ones that MkDocs uses by default (
For example, to enable the SmartyPants typography extension, use:
markdown_extensions: - smarty
Some extensions provide configuration options of their own. If you would like to
set any configuration options, then you can nest a key/value mapping
option_name: option value) of any options that a given extension supports.
See the documentation for the extension you are using to determine what options
For example, to enable permalinks in the (included)
toc extension, use:
markdown_extensions: - toc: permalink: True
Note that a colon (
:) must follow the extension name (
toc) and then on a new
line the option name and value must be indented and separated by a colon. If you
would like to define multiple options for a single extension, each option must be
defined on a separate line:
markdown_extensions: - toc: permalink: True separator: "_"
Add an additional item to the list for each extension. If you have no configuration options to set for a specific extension, then simply omit options for that extension:
markdown_extensions: - smarty - toc: permalink: True - sane_lists
The Python-Markdown documentation provides a list of extensions which are available out-of-the-box. For a list of configuration options available for a given extension, see the documentation for that extension.
You may also install and use various third party extensions. Consult the documentation provided by those extensions for installation instructions and available configuration options.
 (an empty list).
A list of plugins (with optional configuration settings) to use when building the site . See the Plugins documentation for full details.
plugins config setting is defined in the
mkdocs.yml config file, then
any defaults (such as
search) are ignored and you need to explicitly re-enable
the defaults if you would like to continue using them:
plugins: - search - your_other_plugin
To completely disable all plugins, including any defaults, set the
setting to an empty list:
['search'] (the "search" plugin included with MkDocs).
A search plugin is provided by default with MkDocs which uses lunr.js as a search engine. The following config options are available to alter the behavior of the search plugin:
A regular expression which matches the characters used as word separators when
building the index. By default whitespace and the hyphen (
-) are used. To add
the dot (
.) as a word separator you might do this:
plugins: - search: separator: '[\s\-\.]+'
You may contribute additional languages.
While search does support using multiple languages together, it is best not to add additional languages unless you really need them. Each additional language adds significant bandwidth requirements and uses more browser resources. Generally it is best to keep each instance of MkDocs to a single language.
Lunr Languages does not currently include support for Chinese or other Asian languages. However, some users have reported decent results using Japanese.
Optionally generates a pre-built index of all pages, which provides some performance improvements for larger sites. Before enabling, check that the theme you are using explicitly supports using a prebuilt index (the builtin themes do).
There are two options for prebuilding the index:
Using Node.js setting
node. This option
requires that Node.js be installed and the command
node be on the system
path. If this feature is enabled and fails for any reason, a warning is issued.
You may use the
--strict flag when building to cause such a failure to raise
an error instead.
Using Lunr.py setting
python. Lunr.py is installed
as part of mkdocs and guarantees compatibility with Lunr.js even on languages
other than english. If you find substantial inconsistencies or problems please
report it on Lunr.py's issues and fall back to the Node.js version.
On smaller sites, using a pre-built index is not recommended as it creates a significant increase is bandwidth requirements with little to no noticeable improvement to your users. However, for larger sites (hundreds of pages), the bandwidth increase is relatively small and your users will notice a significant improvement in search performance.
