# Changing the logo and icons

When installing Material for MkDocs, you immediately get access to _over 8,000 
icons_ ready to be used for customization of specific parts of the theme and/or 
when writing your documentation in Markdown. Not enough? You can also add
[additional icons] with minimal effort.

  [additional icons]: #additional-icons

## Configuration

### Logo

[:octicons-tag-24: 0.1.0][Logo support] ·
:octicons-milestone-24: Default: :material-library: – `material/library`

The logo can be changed to a user-provided image (any type, incl. `*.png` and
`*.svg`) located in the `docs` folder, or to any icon bundled with the theme.
Add the following lines to `mkdocs.yml`:

=== ":octicons-image-16: Image"

    ``` yaml
    theme:
      logo: assets/logo.png
    ```

=== ":octicons-package-16: Icon, bundled"

    ``` yaml
    theme:
      icon:
        logo: material/library # (1)!
    ```

    1.  Enter a few keywords to find the perfect icon using our [icon search] and
        click on the shortcode to copy it to your clipboard:

        <div class="mdx-iconsearch" data-mdx-component="iconsearch">
          <input class="md-input md-input--stretch mdx-iconsearch__input" placeholder="Search icon" data-mdx-component="iconsearch-query" value="material library" />
          <div class="mdx-iconsearch-result" data-mdx-component="iconsearch-result" data-mdx-mode="file">
            <div class="mdx-iconsearch-result__meta"></div>
            <ol class="mdx-iconsearch-result__list"></ol>
          </div>
        </div>

  [icon search]: ../reference/icons-emojis.md#search

Normally, the logo in the header and sidebar links to the homepage of the
documentation, which is the same as `site_url`. This behavior can be changed
with the following configuration:

``` yaml
extra:
  homepage: https://example.com
```

### Favicon

[:octicons-tag-24: 0.1.0][Favicon support] ·
:octicons-milestone-24: Default: [`assets/images/favicon.png`][Favicon default]

The favicon can be changed to a path pointing to a user-provided image, which 
must be located in the `docs` folder. Add the following lines to `mkdocs.yml`:

``` yaml
theme:
  favicon: images/favicon.png
```

  [Favicon support]: https://github.com/squidfunk/mkdocs-material/releases/tag/0.1.0
  [Favicon default]: https://github.com/squidfunk/mkdocs-material/blob/master/material/assets/images/favicon.png

### Site icons

Most icons you see on your site, such as navigation icons, can also be changed. For example,
to change the navigation arrows in the footer, add the following lines to `mkdocs.yml`:

```yaml
theme:
  icon:
    previous: fontawesome/solid/angle-left
    next: fontawesome/solid/angle-right
```

The following is a complete list of customizable icons used by the theme:

## Customization

### Additional icons

In order to use custom icons, [extend the theme] and create a new folder named
`.icons` in the [`custom_dir`][custom_dir] you want to use for overrides.
Next, add your `*.svg` icons into a subfolder of the `.icons` folder. Let's say
you downloaded and unpacked the [Bootstrap] icon set, and want to add it to
your project documentation. The structure of your project should look like this:

``` { .sh .no-copy }
.
├─ overrides/
│  └─ .icons/
│     └─ bootstrap/
│        └─ *.svg
└─ mkdocs.yml
```

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

``` yaml
markdown_extensions:
  - pymdownx.emoji:
      emoji_index: !!python/name:materialx.emoji.twemoji
      emoji_generator: !!python/name:materialx.emoji.to_svg
      options:
        custom_icons:
          - overrides/.icons
```

You can now use all :fontawesome-brands-bootstrap: Bootstrap icons anywhere in
Markdown files, as well as everywhere icons can be used in `mkdocs.yml`.
However, note that the syntaxes are slightly different:

- __Using icons in configuration__: take the path of the `*.svg` icon file
  starting at the `.icons` folder and drop the file extension, e.g. for
  `.icons/bootstrap/envelope-paper.svg`, use:

    ``` yaml
    theme:
      icon:
        logo: bootstrap/envelope-paper
    ```

- __Using icons in Markdown files__: additionally to taking the path from the
  `.icons` folder as noted above, replace all `/` with `-` and enclose the icon
  shortcode in two colons:

    ```
    :bootstrap-envelope-paper:
    ```

For further notes on icon usage, please consult the [icon reference].
