+
+The [git-revision-date][11] plugin adds support for displaying the date a 
+document was _last updated_ at the bottom of each page. It can be installed
+with `pip`:
+
+```
+pip install mkdocs-git-revision-date-plugin
+```
+
+Then, add the following to `mkdocs.yml`:
+
+``` yaml
+plugins:
+  - git-revision-date
+```
+
+The following options are supported:
+
+`enabled_if_env`{: #enabled_if_env }
+
+:   :octicons-milestone-24: Default: _none_ – This option defines whether the
+    date is actually extracted from git, which makes it possible to disable
+    extraction for cases when the repository is not available:
+
+    ``` yaml
+    plugins:
+      - git-revision-date:
+          enabled_if_env: CI
+    ```
+
+_Material for MkDocs doesn't provide official support for the other options of
+this plugin, so they may be supported but can also yield weird results. Use

+
+Similarly, the [git-revision-date-localized][12] plugin adds support for adding 
+a localized _last updated_ date at the bottom of each page. It can be installed
+with `pip`:
+
+```
+pip install mkdocs-git-revision-date-localized-plugin
+```
+
+Then, add the following to `mkdocs.yml`:
+
+``` yaml
+plugins:
+  - git-revision-date-localized
+```
+
+The following options are supported:
+
+`type`{: #type }
+
+:   :octicons-milestone-24: Default: `date` – This option allows to change the
+    format of the date to be displayed. Valid values are `date`, `datetime`,
+    `iso_date`, `iso_datetime` and `timeago`:
+
+    ``` yaml
+    plugins:
+      - git-revision-date-localized:
+          type: date
+    ```
+
+`fallback_to_build_date`{: #fallback_to_build_date }
+
+:   :octicons-milestone-24: Default: `false` – This option specifies whether
+    the time when `mkdocs build` was executed should be used as a fallback when
+    the git repository is not available:
+
+    ``` yaml
+    plugins:
+      - git-revision-date-localized:
+          fallback_to_build_date: true
