# Setting up a blog

Material for MkDocs makes it very easy to build a blog, either as a sidecar to
your documentation or standalone. Focus on your content while the engine does
all the heavy lifting, automatically generating [archive] and [category]
indexes, [post slugs], configurable [pagination] and more.

## Configuration

### Built-in blog plugin

<!-- md:version 9.2.0 -->
<!-- md:plugin -->
<!-- md:flag experimental -->

The built-in blog plugin adds support for building a blog from a folder of
posts, which are annotated with dates and other structured data. First, add the
following lines to `mkdocs.yml`:

``` yaml
plugins:
  - blog
```

For a list of all settings, please consult the [plugin documentation].

#### Advanced settings :material-alert-decagram:{ .mdx-pulse title="Added on November 23, 2023" }

<!-- md:sponsors -->
<!-- md:version insiders-4.44.0 -->

The following advanced settings are currently reserved to our [sponsors]
[Insiders]. They are entirely optional, and don't affect the functionality of
the blog, but can be helpful for customizations:

- [`archive_pagination`][config.archive_pagination]
- [`archive_pagination_per_page`][config.archive_pagination_per_page]
- [`categories_sort_by`][config.categories_sort_by]
- [`categories_sort_reverse`][config.categories_sort_reverse]

### RSS

<!-- md:version 9.2.0 -->
<!-- md:plugin [rss] -->

The [built-in blog plugin] integrates seamlessly with the [RSS plugin][rss],
which provides a simple way to add an RSS feed to your blog (or to your whole
documentation). Install it with `pip`:

```
pip install mkdocs-rss-plugin
```

Then, add the following lines to `mkdocs.yml`:

``` yaml
plugins:
  - rss:
      match_path: blog/posts/.* # (1)!
      date_from_meta:
        as_creation: date
      categories:
        - categories
        - tags # (2)!
```

1.  The RSS plugin allows to filter for URLs to be included in the feed. In
    this example, only blog posts will be part of the feed.

2.  If you want to include a post's categories as well as its tags in the feed,
    add both `categories` and `tags` here.

The following configuration options are supported:

<!-- md:option rss.enabled -->

:   <!-- md:default `true` --> This option specifies whether
    the plugin is enabled when building your project. If you want to speed up
    local builds, you can use an [environment variable]:

    ``` yaml
    plugins:
      - rss:
          enabled: !ENV [CI, false]
    ```

<!-- md:option rss.match_path -->

:   <!-- md:default `.*` --> This option specifies which
    pages should be included in the feed. For example, to only include blog
    posts in the feed, use the following regular expression:

    ``` yaml
    plugins:
      - rss:
          match_path: blog/posts/.*
    ```

<!-- md:option rss.date_from_meta -->

:   <!-- md:default none --> This option specifies which
    front matter property should be used as a creation date of a page in the
    feed. It's recommended to use the `date` property:

    ``` yaml
    plugins:
      - rss:
          date_from_meta:
            as_creation: date
    ```

<!-- md:option rss.categories -->

:   <!-- md:default none --> This option specifies which
    front matter properties are used as categories as part of the feed. If you
    use [categories] and [tags], add both with the following lines:

    ``` yaml
    plugins:
      - rss:
          categories:
            - categories
            - tags
    ```

<!-- md:option rss.comments_path -->

:   <!-- md:default none --> This option specifies the anchor
    at which comments for a post or page can be found. If you've integrated a
    [comment system], add the following lines:

    ``` yaml
    plugins:
      - rss:
          comments_path: "#__comments"
    ```

Material for MkDocs will automatically add the [necessary metadata] to your site
which will make the RSS feed discoverable by browsers and feed readers. Note
that the [RSS plugin][rss] comes with several other configuration options.
For further information, see the [documentation].

  [theme extension]: ../customization.md
  [documentation]: https://guts.github.io/mkdocs-rss-plugin/configuration/

### Blog only

You might need to build a pure blog without any documentation.
In this case, you can create a folder tree like this:

``` { .sh .no-copy }
.
├─ docs/
│  ├─ posts/ # (1)!
│  ├─ .authors.yml
│  └─ index.md
└─ mkdocs.yml
```

1.  Notice that the `posts` directory is in the root of `docs` without
    intermediate `blog` directory.

And add the following lines to `mkdocs.yml`:

``` yaml
plugins:
  - blog:
      blog_dir: . # (1)!
```

1.  More info about [blog_dir](../plugins/blog.md#config.blog_dir)

With this configuration, the url of the blog post will be `/<post_slug>`
instead of `/blog/<post_slug>`.

## Usage

### Writing your first post

After you've successfully set up the [built-in blog plugin], it's time to write
your first post. The plugin doesn't assume any specific directory structure, so
you're completely free in how you organize your posts, as long as they are all
located inside the `posts` directory:

``` { .sh .no-copy }
.
├─ docs/
│  └─ blog/
│     ├─ posts/
│     │  └─ hello-world.md # (1)!
│     └─ index.md
└─ mkdocs.yml
```

1.  If you'd like to arrange posts differently, you're free to do so. The URLs
    are built from the format specified in [`post_url_format`][post slugs] and
    the titles and dates of posts, no matter how they are organized
    inside the `posts` directory.

Create a new file called `hello-world.md` and add the following lines:

``` yaml
---
draft: true # (1)!
date: 2023-01-31 # (2)!
categories:
  - Hello
  - World
---

# Hello world!
...
```

1.  If you mark a post as a [draft], a red marker appears next to the post date
    on index pages. When the site is built, drafts are not included in the
    output. [This behavior can be changed], e.g. for rendering drafts when
    building deploy previews.

2.  If you wish to provide multiple dates, you can use the following syntax,
    allowing you to define a date when you last updated the blog post +
    further custom dates you can add to the template:

    ``` yaml
    ---
    date:
      created: 2022-01-31
      updated: 2022-02-02
    ---

    # Hello world!
    ```

    Note that the creation date __must__ be set under `date.created`, as each
    blog post must have a creation date set.

When you spin up the [live preview server], you should be greeted by your first
post! You'll also realize, that [archive] and [category] indexes have been
automatically generated for you.

  [draft]: ../plugins/blog.md#drafts
  [This behavior can be changed]: ../plugins/blog.md#config.draft
  [live preview server]: ../creating-your-site.md#previewing-as-you-write

#### Adding an excerpt

The blog index, as well as [archive] and [category] indexes can either list the
entire content of each post, or excerpts of posts. An excerpt can be created by
adding a `<!-- more -->` separator after the first few paragraphs of a post:

``` py
# Hello world!

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla et euismod
nulla. Curabitur feugiat, tortor non consequat finibus, justo purus auctor
massa, nec semper lorem quam in massa.

<!-- more -->
...
```

When the [built-in blog plugin] generates all indexes, the content before the
[excerpt separator] is automatically extracted, allowing the user to start
reading a post before deciding to jump in.

  [excerpt separator]: ../plugins/blog.md#config.post_excerpt_separator

#### Adding authors

In order to add a little more personality to your posts, you can associate each
post with one or multiple [authors]. First, create the
[`.authors.yml`][authors_file] file in your blog directory, and add an author:

``` yaml
authors:
  squidfunk:
    name: Martin Donath
    description: Creator
    avatar: https://github.com/squidfunk.png
```

The [`.authors.yml`][authors_file] file associates each author with an
identifier (in this example `squidfunk`), which can then be used in posts.
Different attributes can be configured. For a list of all possible attributes,
please consult the [`authors_file`][authors_file] documentation.

Now, you can assign one or more authors to a post by referencing their
identifiers in the front matter of the Markdown file under the `authors`
property. For each author, a small profile is rendered in the left sidebar of
each post, as well as in post excerpts on index pages:

``` yaml
---
date: 2023-01-31
authors:
  - squidfunk
    ...
---

# Hello world!
...
```

  [authors]: ../plugins/blog.md#authors
  [authors_file]: ../plugins/blog.md#config.authors_file

#### Adding author profiles :material-alert-decagram:{ .mdx-pulse title="Added on November 26, 2023" }

<!-- md:sponsors -->
<!-- md:version insiders-4.46.0 -->
<!-- md:flag experimental -->

If you wish to add a dedicated page for each author, you can enable author
profiles by setting the [`authors_profiles`][authors_profiles] configuration
option to `true`. Just add the following lines to `mkdocs.yml`:

``` yaml
plugins:
  - blog:
      authors_profiles: true
```

If you combine this with [custom index pages], you can create a dedicated page
for each author with a short description, social media links, etc. – basically
anything you can write in Markdown. The list of posts is then appended after
the content of the page.

  [authors_profiles]: ../plugins/blog.md#config.authors_profiles
  [custom index pages]: #custom-index-pages

#### Adding categories

Categories are an excellent way for grouping your posts thematically on
dedicated index pages. This way, a user interested in a specific topic can
explore all of your posts on this topic. Make sure [categories] are enabled and
add them to the front matter `categories` property:

``` yaml
---
date: 2023-01-31
categories:
  - Hello
  - World
---

# Hello world!
...
```

If you want to save yourself from typos when typing out categories, you can
define your desired categories in `mkdocs.yml` as part of the
[`categories_allowed`][categories_allowed] configuration option. The
[built-in blog plugin] will stop the build if a category is not found within
the list.

  [categories_allowed]: ../plugins/blog.md#config.categories_allowed

#### Adding tags

Besides [categories], the [built-in blog plugin] also integrates with the
[built-in tags plugin]. If you add tags in the front matter `tags` property as
part of a post, the post is linked from the [tags index]:

``` yaml
---
date: 2023-01-31
tags:
  - Foo
  - Bar
---

# Hello world!
...
```

As usual, the tags are rendered above the main headline and posts are linked
on the tags index page, if configured. Note that posts are, as pages, only
linked with their titles.

  [built-in tags plugin]: ../plugins/tags.md
  [tags index]: setting-up-tags.md#adding-a-tags-index

#### Changing the slug

Slugs are the shortened description of your post used in the URL. They are automatically generated, but you can specify a custom slug for a page:

``` yaml
---
slug: hello-world
---

# Hello there world!
...
```

#### Adding related links

<!-- md:sponsors -->
<!-- md:version insiders-4.23.0 -->
<!-- md:flag experimental -->

Related links offer the perfect way to prominently add a _further reading_
section to your post that is included in the left sidebar, guiding the user to
other destinations of your documentation. Use the front matter `links` property
to add related links to a post:

``` yaml
---
date: 2023-01-31
links:
  - plugins/search.md
  - insiders/index.md#how-to-become-a-sponsor
---

# Hello world!
...
```

You can use the exact same syntax as for the [`nav`][nav] section in
`mkdocs.yml`, which means you can set explicit titles for links, add external
links and even use nesting:

``` yaml
---
date: 2023-01-31
links:
  - plugins/search.md
  - insiders/index.md#how-to-become-a-sponsor
  - Nested section:
    - External link: https://example.com
    - setup/setting-up-site-search.md
---

# Hello world!
...
```

If you look closely, you'll realize that you can even use an anchor to link to
a specific section of a document, extending the possibilities of the [`nav`][nav]
syntax in `mkdocs.yml`. The [built-in blog plugin] resolves the anchor and sets
the title of the anchor as a [subtitle] of the related link.

Note that all links must be relative to [`docs_dir`][docs_dir], as is also the
case for the [`nav`][nav] setting.

  [nav]: https://www.mkdocs.org/user-guide/configuration/#nav
  [subtitle]: ../reference/index.md#setting-the-page-subtitle

#### Linking from and to posts

While [post URLs][post slugs] are dynamically computed, the [built-in blog
plugin] ensures that all links from and to posts and a post's assets are
correct. If you want to link to a post, just use the path to the Markdown file
as a link reference (links must be relative):

``` markdown
[Hello World!](blog/posts/hello-world.md)
```

Linking from a post to a page, e.g. the index, follows the same method:

``` markdown
[Blog](../index.md)
```

All assets inside the `posts` directory are copied to the `blog/assets` folder
when the site is being built. Of course, you can also reference assets from
posts outside of the `posts` directory. The [built-in blog plugin] ensures that
all links are correct.

#### Setting the reading time

When [enabled], the [readtime] package is used to compute the expected reading
time of each post, which is rendered as part of the post and post excerpt.
Nowadays, many blogs show reading times, which is why the [built-in blog plugin]
offers this capability as well.

Sometimes, however, the computed reading time might not feel accurate, or
result in odd and unpleasant numbers. For this reason, reading time can be
overridden and explicitly set with the front matter `readtime` property for a
post:

``` yaml
---
date: 2023-01-31
readtime: 15
---

# Hello world!
...
```

This will disable automatic reading time computation.

  [readtime]: https://pypi.org/project/readtime/
  [enabled]: ../plugins/blog.md#config.post_readtime

#### Setting defaults

If you have a lot of posts, it might feel redundant to define all of the above
for each post. Luckily, the [built-in meta plugin] allows to set default front
matter properties per folder. You can group your posts by categories, or
authors, and add a `.meta.yml` file to set common properties:

``` { .sh .no-copy }
.
├─ docs/
│  └─ blog/
│     ├─ posts/
│     ├─ .meta.yml # (1)!
│     └─ index.md
└─ mkdocs.yml
```

1.  As already noted, you can also place a `.meta.yml` file in nested folders
    of the `posts` directory. This file then can define all front matter
    properties that are valid in posts, e.g.:

    ``` yaml
    authors:
      - squidfunk
    categories:
      - Hello
      - World
    ```

Note that order matters – the [built-in meta plugin] must be defined before the
blog plugin in `mkdocs.yml`, so that all set defaults are correctly picked up
by the [built-in blog plugin]:

``` yaml
plugins:
  - meta
  - blog
```

Lists and dictionaries in `.meta.yml` files are merged and deduplicated with the
values defined for a post, which means you can define common properties in
`.meta.yml` and then add specific properties or overrides for each post.

  [built-in meta plugin]: ../plugins/meta.md

### Adding pages

Besides posts, it's also possible to add static pages to your blog by listing
the pages in the [`nav`][nav] section of `mkdocs.yml`. All generated indexes
are included after the last specified page. For example, to add a page on the
authors of the blog, add the following to `mkdocs.yml`:

``` yaml
nav:
  - Blog:
    - blog/index.md
    - blog/authors.md
      ...
```

## Customization

### Custom index pages

<!-- md:sponsors -->
<!-- md:version insiders-4.24.0 -->
<!-- md:flag experimental -->

If you want to add custom content to automatically generated [archive] and
[category] indexes, e.g. to add a category description prior to the list of
posts, you can manually create the category page in the same location where
the [built-in blog plugin] would create it:

``` { .sh .no-copy }
.
├─ docs/
│  └─ blog/
│     ├─ category/
│     │  └─ hello.md # (1)!
│     ├─ posts/
│     └─ index.md
└─ mkdocs.yml
```

1.  The easiest way is to first [add the category] to the blog post, then take
    the URL generated by the [built-in blog plugin] and create the file at the
    corresponding location in the [`blog_dir`][this is configurable] folder.

    Note that the shown directory listing is based on the default configuration.
    If you specify different values for the following options, be sure to adjust
    the path accordingly:

    - [`blog_dir`][this is configurable]
    - [`categories_url_format`][categories_url_format]
    - [`categories_slugify`][categories_slugify]

You can now add arbitrary content to the newly created file, or set specific
front matter properties for this page, e.g. to change the [page description]:

``` yaml
---
description: Nullam urna elit, malesuada eget finibus ut, ac tortor.
---

# Hello
...
```

All post excerpts belonging to the category are automatically appended.

  [add the category]: #adding-categories
  [page description]: ../reference/index.md#setting-the-page-description
  [categories_url_format]: ../plugins/blog.md#config.categories_url_format
  [categories_slugify]: ../plugins/blog.md#config.categories_slugify

### Overriding templates

The [built-in blog plugin] is built on the same basis as Material for MkDocs,
which means you can override all templates used for the blog by using
[theme extension] as usual.

The following templates are added by the [built-in blog plugin]:

- [`blog.html`][blog.html] – Template for blog, archive and category index
- [`blog-post.html`][blog-post.html] – Template for blog post

  [theme extension]: ../customization.md#extending-the-theme

  [blog.html]: https://github.com/squidfunk/mkdocs-material/blob/master/src/blog.html
  [blog-post.html]: https://github.com/squidfunk/mkdocs-material/blob/master/src/blog-post.htmlhtml
