<p>Guide to all available configuration settings.</p>
<hr />
<h2 id="introduction">Introduction<a class="headerlink" href="#introduction" title="Permanent link"></a></h2>
<p>Project settings are configured by default using a YAML configuration file in
the project directory named <code>mkdocs.yml</code>. You can specify another path for it
by using the <code>-f</code>/<code>--config-file</code> option (see <code>mkdocs build --help</code>).</p>
<p>As a minimum, this configuration file must contain the <code>site_name</code>. All other settings are optional.</p>
<h2 id="project-information">Project information<a class="headerlink" href="#project-information" title="Permanent link"></a></h2>
<h3 id="site_name">site_name<a class="headerlink" href="#site_name" title="Permanent link"></a></h3>
<p>This is a <strong>required setting</strong>, and should be a string that is used as the main
title for the project documentation. For example:</p>
<pre class="highlight"><code class="language-yaml">site_name: Marshmallow Generator</code></pre>
<p>When rendering the theme this setting will be passed as the <code>site_name</code> context
variable.</p>
<h3 id="site_url">site_url<a class="headerlink" href="#site_url" title="Permanent link"></a></h3>
<p>Set the canonical URL of the site. This will add a <code>link</code> tag with the
<code>canonical</code> URL to the <code>head</code> section of each HTML page. If the 'root' of the
MkDocs site will be within a subdirectory of a domain, be sure to include that
subdirectory in the setting (<code>https://example.com/foo/</code>).</p>
<p>This setting is also used for <code>mkdocs serve</code>: the server will be mounted onto a
path taken from the path component of the URL, e.g. <code>some/page.md</code> will be
served from <code>http://127.0.0.1:8000/foo/some/page/</code> to mimic the expected remote
layout.</p>
<p><strong>default</strong>: <code>null</code></p>
<h3 id="repo_url">repo_url<a class="headerlink" href="#repo_url" title="Permanent link"></a></h3>
<p>When set, provides a link to your repository (GitHub, Bitbucket, GitLab, ...)
on each page.</p>
<pre class="highlight"><code class="language-yaml">repo_url: https://github.com/example/repository/</code></pre>
<p><strong>default</strong>: <code>null</code></p>
<h3 id="repo_name">repo_name<a class="headerlink" href="#repo_name" title="Permanent link"></a></h3>
<p>When set, provides the name for the link to your repository on each page.</p>
<p><strong>default</strong>: <code>'GitHub'</code>, <code>'Bitbucket'</code> or <code>'GitLab'</code> if the <code>repo_url</code> matches
those domains, otherwise the hostname from the <code>repo_url</code>.</p>
<h3 id="edit_uri">edit_uri<a class="headerlink" href="#edit_uri" title="Permanent link"></a></h3>
<p>The path from the base <code>repo_url</code> 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 <code>repo_url</code>
and <code>edit_uri</code>, and appends the input path of the page.</p>
<p>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
page. If <code>repo_url</code> 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.</p>
<p>The <code>edit_uri</code> supports query ('?') and fragment ('#') characters. For
repository hosts that use a query or a fragment to access the files, the
<code>edit_uri</code> might be set as follows. (Note the <code>?</code> and <code>#</code> in the URI...)</p>
<pre class="highlight"><code class="language-yaml"># Query string example
edit_uri: '?query=root/path/docs/'</code></pre>
<pre class="highlight"><code class="language-yaml"># Hash fragment example
edit_uri: '#root/path/docs/'</code></pre>
<p>For other repository hosts, simply specify the relative path to the docs
directory.</p>
<pre class="highlight"><code class="language-yaml"># Query string example
edit_uri: root/path/docs/</code></pre>
<p>For example, having this config:</p>
<pre class="highlight"><code class="language-yaml">repo_url: https://example.com/project/repo
edit_uri: blob/main/docs/</code></pre>
<p>means that a page named 'foo/bar.md' will have its edit link lead to:<br />
<a href="https://example.com/project/repo/blob/main/docs/foo/bar.md">https://example.com/project/repo/blob/main/docs/foo/bar.md</a></p>
<p><code>edit_uri</code> can actually be just an absolute URL, not necessarily relative to <code>repo_url</code>, so this can achieve the same result:</p>
<pre class="highlight"><code class="language-yaml">edit_uri: https://example.com/project/repo/blob/main/docs/</code></pre>
<p>For more flexibility, see <a href="#edit_uri_template">edit_uri_template</a> below.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>
On a few known hosts (specifically GitHub, Bitbucket and GitLab), the
<code>edit_uri</code> is derived from the 'repo_url' and does not need to be set
manually. Simply defining a <code>repo_url</code> will automatically populate the
<code>edit_uri</code> configs setting.</p>
<p>For example, for a GitHub- or GitLab-hosted repository, the <code>edit_uri</code>
would be automatically set as <code>edit/master/docs/</code> (Note the <code>edit</code> path
and <code>master</code> branch).</p>
<p>For a Bitbucket-hosted repository, the equivalent <code>edit_uri</code> would be
automatically set as <code>src/default/docs/</code> (note the <code>src</code> path and <code>default</code>
branch).</p>
<p>To use a different URI than the default (for example a different branch),
simply set the <code>edit_uri</code> to your desired string. If you do not want any
"edit URL link" displayed on your pages, then set <code>edit_uri</code> to an empty
string to disable the automatic setting.</p>
</div>
<div class="admonition warning">
<p class="admonition-title">Warning</p>
<p>
On GitHub and GitLab, the default "edit" path (<code>edit/master/docs/</code>) opens
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
(<code>blob/master/docs/</code>) to open a read-only view, which supports anonymous
access.</p>
</div>
<p><strong>default</strong>: <code>edit/master/docs/</code> for GitHub and GitLab repos or
<code>src/default/docs/</code> for a Bitbucket repo, if <code>repo_url</code> matches those domains,
otherwise <code>null</code></p>
<h3 id="edit_uri_template">edit_uri_template<a class="headerlink" href="#edit_uri_template" title="Permanent link"></a></h3>
<p>The more flexible variant of <a href="#edit_uri">edit_uri</a>. These two are equivalent:</p>
<pre class="highlight"><code class="language-yaml">edit_uri: 'blob/main/docs/'
edit_uri_template: 'blob/main/docs/{path}'</code></pre>
<p>(they are also mutually exclusive -- don't specify both).</p>
<p>Starting from here, you can change the positioning or formatting of the path, in case the default behavior of appending the path isn't enough.</p>
<p>The contents of <code>edit_uri_template</code> are normal <a href="https://docs.python.org/3/library/string.html#formatstrings">Python format strings</a>, with only these fields available:</p>
<ul>
<li><code>{path}</code>, e.g. <code>foo/bar.md</code></li>
<li><code>{path_noext}</code>, e.g. <code>foo/bar</code></li>
</ul>
<p>And the conversion flag <code>!q</code> is available, to percent-encode the field:</p>
<ul>
<li><code>{path!q}</code>, e.g. <code>foo%2Fbar.md</code></li>
</ul>

<h2 id="documentation-layout">Documentation layout<a class="headerlink" href="#documentation-layout" title="Permanent link"></a></h2>
<h3 id="nav">nav<a class="headerlink" href="#nav" title="Permanent link"></a></h3>
<p>This setting is used to determine the format and layout of the global navigation
for the site. A minimal navigation configuration could look like this:</p>
<pre class="highlight"><code class="language-yaml">nav:
- 'index.md'
- 'about.md'</code></pre>
<p>All paths in the navigation configuration must be relative to the
<a href="#docs_dir"><code>docs_dir</code></a> configuration option. See the section on <a href="../writing-your-docs/#configure-pages-and-navigation">configuring
pages and navigation</a> for a more detailed breakdown, including how to create
sub-sections.</p>
<p>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. See the section about [Meta-Data] on
how MkDocs determines the page title of a document.</p>
<pre class="highlight"><code class="language-yaml">nav:
- Introduction: 'index.md'
- 'about.md'
- 'Issue Tracker': 'https://example.com/'</code></pre>
<p>In the above example, the first two items point to local files while the third
points to an external site.</p>
<p>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 an appropriate relative URL.</p>
<pre class="highlight"><code class="language-yaml">site_url: https://example.com/foo/
nav:
- Home: '../'
- 'User Guide': 'user-guide.md'
- 'Bug Tracker': '/bugs/'</code></pre>
<p>In the above example, two different styles of external links are used. First,
note that the <code>site_url</code> indicates that the MkDocs site is hosted in the <code>/foo/</code>
subdirectory of the domain. Therefore, the <code>Home</code> navigation item is a relative
link that steps up one level to the server root and effectively points to
<code>https://example.com/</code>. The <code>Bug Tracker</code> item uses an absolute path from the
server root and effectively points to <code>https://example.com/bugs/</code>. Of course, the
<code>User Guide</code> points to a local MkDocs page.</p>
<p><strong>default</strong>: By default <code>nav</code> will contain an alphanumerically sorted, nested
list of all the Markdown files found within the <code>docs_dir</code> and its
sub-directories. Index files will always be listed first within a sub-section.</p>
<h2 id="build-directories">Build directories<a class="headerlink" href="#build-directories" title="Permanent link"></a></h2>
<h3 id="theme">theme<a class="headerlink" href="#theme" title="Permanent link"></a></h3>
<p>Sets the theme and theme specific configuration of your documentation site.
May be either a string or a set of key/value pairs.</p>
<p>If a string, it must be the string name of a known installed theme. For a list
of available themes visit <a href="../choosing-your-theme/">Choosing Your Theme</a>.</p>
<p>An example set of key/value pairs might look something like this:</p>
<pre class="highlight"><code class="language-yaml">theme:
name: mkdocs
locale: en
custom_dir: my_theme_customizations/
static_templates:
- sitemap.html
include_sidebar: false</code></pre>
<p>If a set of key/value pairs, the following nested keys can be defined:</p>
<div class="admonition block">
<p class="admonition-title">Block</p>
<h4 id="name">

<h3 id="site_dir">site_dir<a class="headerlink" href="#site_dir" title="Permanent link"></a></h3>
<p>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.</p>
<p><strong>default</strong>: <code>'site'</code></p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>
If you are using source code control you will normally want to ensure that
your <em>build output</em> files are not committed into the repository, and only
keep the <em>source</em> files under version control. For example, if using <code>git</code>
you might add the following line to your <code>.gitignore</code> file:</p>
<pre class="highlight"><code class="language-text">site/</code></pre>
<p>If you're using another source code control tool, you'll want to check its
documentation on how to ignore specific directories.</p>

<p>Set a list of CSS files in your <code>docs_dir</code> to be included by the theme. For
example, the following example will include the extra.css file within the
css subdirectory in your <a href="#docs_dir">docs_dir</a>.</p>
<pre class="highlight"><code class="language-yaml">extra_css:
- css/extra.css
- css/second_extra.css</code></pre>
<p><strong>default</strong>: <code>[]</code> (an empty list).</p>
<h3 id="extra_javascript">extra_javascript<a class="headerlink" href="#extra_javascript" title="Permanent link"></a></h3>
<p>Set a list of JavaScript files in your <code>docs_dir</code> to be included by the theme.

<h3 id="use_directory_urls">use_directory_urls<a class="headerlink" href="#use_directory_urls" title="Permanent link"></a></h3>
<p>This setting controls the style used for linking to pages within the

<p>The default style of <code>use_directory_urls: true</code> creates more user friendly URLs,
and is usually what you'll want to use.</p>
<p>The alternate style can 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 <em>file</em> rather than the target
<em>directory</em>.</p>
<p><strong>default</strong>: <code>true</code></p>
<h3 id="strict">strict<a class="headerlink" href="#strict" title="Permanent link"></a></h3>
<p>Determines how warnings are handled. Set to <code>true</code> to halt processing when a
warning is raised. Set to <code>false</code> to print a warning and continue processing.</p>
<p>This is also available as a command line flag: <code>--strict</code>.</p>
<p><strong>default</strong>: <code>false</code></p>
<h3 id="dev_addr">dev_addr<a class="headerlink" href="#dev_addr" title="Permanent link"></a></h3>
<p>Determines the address used when running <code>mkdocs serve</code>. Must be of the format
<code>IP:PORT</code>.</p>

<p>MkDocs uses the <a href="https://python-markdown.github.io/">Python Markdown</a> library to translate Markdown files
into HTML. Python Markdown supports a variety of <a href="https://python-markdown.github.io/extensions/">extensions</a>
that customize how pages are formatted. This setting lets you enable a list of
extensions beyond the ones that MkDocs uses by default (<code>meta</code>, <code>toc</code>, <code>tables</code>,
and <code>fenced_code</code>).</p>
<p>For example, to enable the <a href="https://python-markdown.github.io/extensions/smarty/">SmartyPants typography extension</a>, use:</p>
<pre class="highlight"><code class="language-yaml">markdown_extensions:
- smarty</code></pre>
<p>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
(<code>option_name: option value</code>) of any options that a given extension supports.
See the documentation for the extension you are using to determine what options
they support.</p>
<p>For example, to enable permalinks in the (included) <code>toc</code> extension, use:</p>
<pre class="highlight"><code class="language-yaml">markdown_extensions:
- toc:
permalink: True</code></pre>
<p>Note that a colon (<code>:</code>) must follow the extension name (<code>toc</code>) 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:</p>
<pre class="highlight"><code class="language-yaml">markdown_extensions:
- toc:
permalink: True
separator: "_"</code></pre>
<p>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:</p>
<pre class="highlight"><code class="language-yaml">markdown_extensions:
- smarty
- toc:
permalink: True
- sane_lists</code></pre>
<p>In the above examples, each extension is a list item (starts with a <code>-</code>). As an
alternative, key/value pairs can be used instead. However, in that case an empty
value must be provided for extensions for which no options are defined.
Therefore, the last example above could also be defined as follows:</p>
<pre class="highlight"><code class="language-yaml">markdown_extensions:
smarty: {}
toc:
permalink: True
sane_lists: {}</code></pre>
<p>This alternative syntax is required if you intend to override some options via
<a href="#configuration-inheritance">inheritance</a>.</p>
<div class="admonition note">
<p class="admonition-title">See Also:</p>
<p>The Python-Markdown documentation provides a <a href="https://python-markdown.github.io/extensions/">list of extensions</a>
which are available out-of-the-box. For a list of configuration options
available for a given extension, see the documentation for that extension.</p>
<p>You may also install and use various third party extensions (<a href="https://github.com/Python-Markdown/markdown/wiki/Third-Party-Extensions">Python-Markdown wiki</a>, <a href="https://github.com/mkdocs/best-of-mkdocs">Best-of-MkDocs</a>). Consult

<p>A list of paths to Python scripts (relative to <code>mkdocs.yml</code>) that are loaded and used as <a href="#plugins">plugin</a> instances.</p>
<p>For example:</p>
<pre class="highlight"><code class="language-yaml">hooks:
- my_hooks.py</code></pre>
<p>Then the file <em>my_hooks.py</em> can contain any <a href="../../dev-guide/plugins/#events">plugin event handlers</a> (without <code>self</code>), e.g.:</p>
<pre class="highlight"><code class="language-python">def on_page_markdown(markdown, **kwargs):
return markdown.replace('a', 'z')</code></pre>
<details class="example">
<summary>Advanced example:</summary>
<p>This produces warnings based on the Markdown content (and warnings are fatal in <a href="#strict">strict</a> mode):</p>
<pre class="highlight"><code class="language-python">import logging, re
import mkdocs.plugins
log = logging.getLogger('mkdocs')
@mkdocs.plugins.event_priority(-50)
def on_page_markdown(markdown, page, **kwargs):
path = page.file.src_uri
for m in re.finditer(r'\bhttp://[^) ]+', markdown):
log.warning(f"Documentation file '{path}' contains a non-HTTPS link: {m[0]}")</code></pre>
</details>
<p>This does not enable any new abilities compared to <a href="../../dev-guide/plugins/">plugins</a>, it only simplifies one-off usages, as these don't need to be <em>installed</em> like plugins do.</p>
<p>Note that for <code>mkdocs serve</code> the hook module will <em>not</em> be reloaded on each build.</p>
<p>You might have seen this feature in the <a href="https://github.com/aklajnert/mkdocs-simple-hooks">mkdocs-simple-hooks plugin</a>. If using standard method names, it can be directly replaced, e.g.:</p>
<pre class="highlight"><code class="language-diff">-plugins:
- - mkdocs-simple-hooks:
- hooks:
- on_page_markdown: 'my_hooks:on_page_markdown'
+hooks:

<h3 id="plugins">plugins<a class="headerlink" href="#plugins" title="Permanent link"></a></h3>
<p>A list of plugins (with optional configuration settings) to use when building
the site. See the <a href="../../dev-guide/plugins/">Plugins</a> documentation for full details.</p>
<p>If the <code>plugins</code> config setting is defined in the <code>mkdocs.yml</code> config file, then
any defaults (such as <code>search</code>) are ignored and you need to explicitly re-enable
the defaults if you would like to continue using them:</p>
<pre class="highlight"><code class="language-yaml">plugins:
- search
- your_other_plugin</code></pre>
<p>To define options for a given plugin, use a nested set of key/value pairs:</p>
<pre class="highlight"><code class="language-yaml">plugins:
- search
- your_other_plugin:
option1: value
option2: other value</code></pre>
<p>In the above examples, each plugin is a list item (starts with a <code>-</code>). As an
alternative, key/value pairs can be used instead. However, in that case an empty
value must be provided for plugins for which no options are defined. Therefore,
the last example above could also be defined as follows:</p>
<pre class="highlight"><code class="language-yaml">plugins:
search: {}
your_other_plugin:
option1: value
option2: other value</code></pre>
<p>This alternative syntax is required if you intend to override some options via
<a href="#configuration-inheritance">inheritance</a>.</p>
<p>To completely disable all plugins, including any defaults, set the <code>plugins</code>
setting to an empty list:</p>
<pre class="highlight"><code class="language-yaml">plugins: []</code></pre>
<p><strong>default</strong>: <code>['search']</code> (the "search" plugin included with MkDocs).</p>
<h4 id="search">Search<a class="headerlink" href="#search" title="Permanent link"></a></h4>
<p>A search plugin is provided by default with MkDocs which uses <a href="https://lunrjs.com/">lunr.js</a> as a
search engine. The following config options are available to alter the behavior
of the search plugin:</p>
<h5 id="separator"><strong>separator</strong><a class="headerlink" href="#separator" title="Permanent link"></a></h5>
<p>A regular expression which matches the characters used as word separators when
building the index. By default whitespace and the hyphen (<code>-</code>) are used. To add
the dot (<code>.</code>) as a word separator you might do this:</p>
<pre class="highlight"><code class="language-yaml">plugins:
- search:
separator: '[\s\-\.]+'</code></pre>
<p><strong>default</strong>: <code>'[\s\-]+'</code></p>
<h5 id="min_search_length"><strong>min_search_length</strong><a class="headerlink" href="#min_search_length" title="Permanent link"></a></h5>
<p>An integer value that defines the minimum length for a search query. By default
searches shorter than 3 chars in length are ignored as search result quality with
short search terms are poor. However, for some use cases (such as documentation
about Message Queues which might generate searches for 'MQ') it may be preferable
to set a shorter limit.</p>
<pre class="highlight"><code class="language-yaml">plugins:
- search:
min_search_length: 2</code></pre>
<p><strong>default</strong>: 3</p>
<h5 id="lang"><strong>lang</strong><a class="headerlink" href="#lang" title="Permanent link"></a></h5>
<p>A list of languages to use when building the search index as identified by their
<a href="https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes">ISO 639-1</a> language codes. With <a href="https://github.com/MihaiValentin/lunr-languages#lunr-languages-----">Lunr Languages</a>, the following languages are

<p>
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.</p>

<div class="admonition warning">
<p class="admonition-title">Warning</p>
<p>
This option requires that <a href="https://nodejs.org/">Node.js</a> be installed and the command <code>node</code> be
on the system path. If the call to <code>node</code> fails for any reason, a warning
is issued and the build continues uninterrupted. You may use the <code>--strict</code>

</div>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>
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.</p>

<h2 id="environment-variables">Environment Variables<a class="headerlink" href="#environment-variables" title="Permanent link"></a></h2>
<p>In most cases, the value of a configuration option is set directly in the
configuration file. However, as an option, the value of a configuration option
may be set to the value of an environment variable using the <code>!ENV</code> tag. For
example, to set the value of the <code>site_name</code> option to the value of the
variable <code>SITE_NAME</code> the YAML file may contain the following:</p>
<pre class="highlight"><code class="language-yaml">site_name: !ENV SITE_NAME</code></pre>
<p>If the environment variable is not defined, then the configuration setting
would be assigned a <code>null</code> (or <code>None</code> in Python) value. A default value can be
defined as the last value in a list. Like this:</p>
<pre class="highlight"><code class="language-yaml">site_name: !ENV [SITE_NAME, 'My default site name']</code></pre>
<p>Multiple fallback variables can be used as well. Note that the last value is
not an environment variable, but must be a value to use as a default if none
of the specified environment variables are defined.</p>
<pre class="highlight"><code class="language-yaml">site_name: !ENV [SITE_NAME, OTHER_NAME, 'My default site name']</code></pre>
<p>Simple types defined within an environment variable such as string, bool,
integer, float, datestamp and null are parsed as if they were defined directly
in the YAML file, which means that the value will be converted to the
appropriate type. However, complex types such as lists and key/value pairs
cannot be defined within a single environment variable.</p>
<p>For more details, see the <a href="https://github.com/waylan/pyyaml-env-tag">pyyaml_env_tag</a>
project.</p>
<h2 id="configuration-inheritance">Configuration Inheritance<a class="headerlink" href="#configuration-inheritance" title="Permanent link"></a></h2>
<p>Generally, a single file would hold the entire configuration for a site.
However, some organizations may maintain multiple sites which all share a common
configuration across them. Rather than maintaining separate configurations for
each, the common configuration options can be defined in a parent configuration
file which each site's primary configuration file inherits.</p>
<p>To define the parent for a configuration file, set the <code>INHERIT</code> (all caps) key
to the path of the parent file. The path must be relative to the location of the
primary file.</p>
<p>For configuration options to be merged with a parent configuration, those
options must be defined as key/value pairs. Specifically, the
<a href="#markdown_extensions">markdown_extensions</a> and <a href="#plugins">plugins</a> options must use the alternative syntax
which does not use list items (lines which start with <code>-</code>).</p>
<p>For example, suppose the common (parent) configuration is defined in <code>base.yml</code>:</p>
<pre class="highlight"><code class="language-yaml">theme:
name: mkdocs
locale: en
highlightjs: true
markdown_extensions:
toc:
permalink: true
admonition: {}</code></pre>
<p>Then, for the "foo" site, the primary configuration file would be defined at
<code>foo/mkdocs.yml</code>:</p>
<pre class="highlight"><code class="language-yml">INHERIT: ../base.yml
site_name: Foo Project
site_url: https://example.com/foo</code></pre>
<p>When running <code>mkdocs build</code>, the file at <code>foo/mkdocs.yml</code> would be passed in as
the configuration file. MkDocs will then parse that file, retrieve and parse the
parent file <code>base.yml</code> and deep merge the two. This would result in MkDocs
receiving the following merged configuration:</p>
<pre class="highlight"><code class="language-yaml">site_name: Foo Project
site_url: https://example.com/foo
theme:
name: mkdocs
locale: en
highlightjs: true
markdown_extensions:
toc:
permalink: true
admonition: {}</code></pre>
<p>Deep merging allows you to add and/or override various values in your primary
configuration file. For example, suppose for one site you wanted to add support
for definition lists, use a different symbol for permalinks, and define a
different separator. In that site's primary configuration file you could do:</p>
<pre class="highlight"><code class="language-yaml">INHERIT: ../base.yml
site_name: Bar Project
site_url: https://example.com/bar
markdown_extensions:
def_list: {}
toc:
permalink: 
separator: "_"</code></pre>
<p>In that case, the above configuration would be deep merged with <code>base.yml</code> and
result in the following configuration:</p>
<pre class="highlight"><code class="language-yaml">site_name: Bar Project
site_url: https://example.com/bar
theme:
name: mkdocs
locale: en
highlightjs: true
markdown_extensions:
def_list: {}
toc:
permalink: 
separator: "_"
admonition: {}</code></pre>
<p>Notice that the <code>admonition</code> extension was retained from the parent
configuration, the <code>def_list</code> extension was added, the value of
<code>toc.permalink</code> was replaced, and the value of <code>toc.separator</code> was added.</p>
<p>You can replace or merge the value of any key. However, any non-key is always
replaced. Therefore, you cannot append items to a list. You must redefine the
entire list.</p>
<p>As the <a href="#nav">nav</a> configuration is made up of nested lists, this means that you
cannot merge navigation items. Of course, you can replace the entire <code>nav</code>
configuration with a new one. However, it is generally expected that the entire
navigation would be defined in the primary configuration file for a project.</p>
<div class="admonition warning">
<p class="admonition-title">Warning</p>
<p>
As a reminder, all path based configuration options must be relative to the
primary configuration file and MkDocs does not alter the paths when merging.
Therefore, defining paths in a parent file which is inherited by multiple
different sites may not work as expected. It is generally best to define
path based options in the primary configuration file only.</p>
