# Built-in plugins

Material for MkDocs started out as a theme for [MkDocs][mkdocs], but has since
evolved into a full-fledged framework for building and maintaining documentation.
The theme is still the core of the project, but it's now accompanied by a
growing number of complementary built-in plugins.

We strive to make those plugins as modular and generic as possible, so that they
can be used in a wide variety of projects and use cases. By providing useful
default settings, we also try to make them as easy to use as possible, so that
you can get started quickly, tweaking their settings later on. When
developing built-in plugins, we always adhere to the following design principles:

- **Modularity:** Built-in plugins are designed to be modular, so that they can
  be easily combined to implement sophisticated pipelines. For example, the
  [offline], [optimize] and [privacy] plugins can be used together to build
  truly [offline-capable documentation].

- **Interoperability:** Built-in plugins are designed to be as compatible as
  possible, so they can be used in combination with other plugins, including
  third-party plugins. We strive to make it simple to integrate with the vast
  ecosystem that has evolved around [MkDocs][mkdocs].

- **Performance:** Built-in plugins are designed to be as fast and
  memory-efficient as possible, so that they don't unnecessarily slow down
  builds. This is particularly important for large documentation projects with
  thousands of pages.

### Management

The following plugins greatly improve the authoring experience when working on
documentation projects by providing better management capabilities, from the
management of plugins, multiple projects, and metadata, to the creation of
minimal reproductions for bug reports:

<div class="grid cards" markdown>

-   :material-format-list-group: &nbsp; __[Built-in group plugin][group]__

    ---

    The group plugin allows to group plugins into logical units to conditionally
    enable or disable them for specific environments with the use of
    [environment variables][mkdocs.env].

    ---

    __Optimal management of plugins when building in different environments__

-   :material-file-tree: &nbsp; __[Built-in meta plugin][meta]__

    ---

    The meta plugin makes it easy to manage metadata (front matter) for all
    pages in a folder, so a certain subset of pages uses specific tags or a
    custom template.

    ---

    __Simpler organization, categorization and management of metadata__

-   :material-folder-open: &nbsp; __[Built-in projects plugin][projects]__

    ---

    The projects plugin allows to split your main project into multiple distinct
    projects, build them concurrently and preview them together as one.

    ---

    __Connect multiple projects together, and build them separately or as one__

-   :material-information: &nbsp; __[Built-in info plugin][info]__

    ---

    The info plugin is a small and useful utility that helps to create
    self-contained minimal reproductions, so we maintainers can fix reported
    bugs more quickly.

    ---

    __Your bug reports are of the highest quality, so we can fix them as fast as
    possible__


</div>

  [group]: group.md
  [info]: info.md
  [meta]: meta.md
  [projects]: meta.md

### Optimization

The following plugins are designed to help you build optimized documentation,
making it more accessible to your users through faster loading times, better
search engine rankings, beautiful preview images on social media, and GDPR
compliance with a few lines of configuration:

<div class="grid cards" markdown>

-   :material-share-circle: &nbsp; __[Built-in social plugin][social]__

    ---

    The social plugin automatically generates beautiful and customizable
    social cards for each page of your documentation, showing as previews on
    social media.

    ---

    __Links to your site render beautiful social cards when shared on social
    media__

-   :material-rabbit: &nbsp; __[Built-in optimize plugin][optimize]__

    ---

    The optimize plugin automatically identifies and optimizes all media files
    that you reference in your project by using compression and conversion
    techniques.

    ---

    __Your site loads faster as smaller images are served to your users__

-   :material-shield-account: &nbsp; __[Built-in privacy plugin][privacy]__

    ---

    The privacy plugin downloads external assets automatically for easy
    self-hosting, allowing for GDPR compliance with a single line of
    configuration.

    ---

    __Your documentation can be made GDPR compliant with minimal effort__

-   :material-connection: &nbsp; __[Built-in offline plugin][offline]__

    ---

    The offline plugin adds support for building [offline-capable documentation],
    so you can distribute the [`site` directory][mkdocs.site_dir] as a `.zip`
    file that can be downloaded.

    ---

    __Your documentation can work without connectivity to the internet__

</div>

  [offline]: offline.md
  [optimize]: optimize.md
  [privacy]: privacy.md
  [social]: social.md

### Content

The following plugins are designed to help you set up a blog, provide search
functionality to your users, add tags to pages and posts, and use the same
typesetting capabilities in specific parts of the documentation exactly as in
the main content:

<div class="grid cards" markdown>

-   :material-newspaper-variant-outline: &nbsp; __[Built-in blog plugin][blog]__

    ---

    The blog plugin adds first-class support for blogging to Material for
    MkDocs, either as a sidecar to your documentation or as a standalone
    installation.

    ---

    __Your blog is built with the same powerful engine as your documentation__

-   :material-magnify: &nbsp; __[Built-in search plugin][search]__

    ---

    The search plugin adds a search bar to the header, allowing users to search
    the entire documentation, so it's easier for them to find what they're
    looking for.

    ---

    __Your documentation is searchable without any external services, even
    offline__

-   :material-tag-text: &nbsp; __[Built-in tags plugin][tags]__

    ---

    The tags plugin adds first-class support for categorizing pages with tags,
    adding the ability to group related pages to improve the discovery of
    related content.

    ---

    __Your pages are categorized with tags, yielding additional context__

-   :material-format-title: &nbsp; __[Built-in typeset plugin][typeset]__

    ---

    The typeset plugin allows to preserve the enriched presentation of titles
    and headlines within the navigation and table of contents.

    ---

    __Sidebars preserve the same formatting as section titles in pages__

</div>

  [blog]: blog.md
  [search]: search.md
  [tags]: tags.md
  [typeset]: typeset.md

## Architecture

### Multiple instances

Several built-in plugins have support for multiple instances, which means that
they can be used multiple times in the same configuration file, allowing to
fine-tune behavior for separate sections of your project. Currently, the
following plugins have support for multiple instances:

<div class="mdx-columns" markdown>

- [Built-in blog plugin][blog]
- [Built-in group plugin][group]
- [Built-in optimize plugin][optimize]
- [Built-in privacy plugin][privacy]
- [Built-in social plugin][social]
