# Revision date

The [mkdocs-git-revision-date-localized-plugin][1] is an extension that shows
the date on which a Markdown file was last updated in at the bottom of each
page. The date is extracted at the time of the build, so `mkdocs build` must be
triggered from within a git repository.

!!! success "Bundled with the official Docker image"

    This plugin is already installed for your convenience when you use the
    official [Docker image][2], so the installation step can be skipped. Read
    the [getting started guide][3] to get up and running with Docker.

  [1]: https://github.com/timvink/mkdocs-git-revision-date-localized-plugin
  [2]: https://hub.docker.com/r/squidfunk/mkdocs-material/
  [3]: ../getting-started.md#with-docker-recommended

## Installation

Install the plugin using `pip`:

``` sh
pip install mkdocs-git-revision-date-localized-plugin
```

## Configuration

Add the following lines to `mkdocs.yml`:

``` yaml
plugins:
  - search # necessary for search to work
  - git-revision-date-localized
```

Note that the date is printed according to the locale which is determined
through the [theme language][2] that was set in `mkdocs.yml`.

  [2]: ../getting-started.md/#language

### Language

The language (i.e. locale) is deduced from the `theme.language` option.

### Format

> Default: `date`

To change the date format, set the `type` parameter to one of `date`,
`datetime`, `iso_date`, `iso_datetime` or `timeago`, e.g.:

``` yaml
plugins:
  - search # necessary for search to work
  - git-revision-date-localized:
      type: date
```

The following formats are supported:

``` gnuplot
28 November, 2019                      # type: date
28 November, 2019 13:57:28             # type: datetime
2019-11-28                             # type: iso_date
2019-11-28 13:57:26                    # type: iso_datetime
20 hours ago                           # type: timeago
```

## Usage

When enabled, the respective date is automatically added at the bottom of each
page, e.g.:
