## Style your wiki content
### Create or edit wiki pages locally
GitLab wikis support Markdown, RDoc, AsciiDoc, and Org for content.
Wikis are based on Git repositories, so you can clone them locally and edit
them like you would do with every other Git repository. To clone a wiki repository
locally, select **Clone repository** from the right-hand sidebar of any wiki page,
and follow the on-screen instructions.
Wiki pages written in Markdown support all [Markdown features](../../markdown.md),
and also provide some [wiki-specific behavior](../../markdown.md#wiki-specific-markdown)
for links.
Files you add to your wiki locally must use one of the following
supported extensions, depending on the markup language you wish to use.
Files with unsupported extensions don't display when pushed to GitLab:
### Store attachments for wiki pages
> - [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/33475) in GitLab 11.3.
When you upload a file to the wiki through the GitLab interface, the file is stored
in the wiki's Git repository. The file is available to you if you clone the
wiki repository locally.
Files uploaded to a wiki in GitLab 11.3 and earlier are stored in GitLab itself.
You must re-upload the files to add them to the wiki's Git repository.

- Slashes (`/`) are used as path separators, and can't be displayed in titles. If you
create a title containing `/` characters, GitLab creates all the subdirectories
needed to build that path. For example, a title of `docs/my-page` creates a wiki
page with a path `/wikis/docs/my-page`.
### Length restrictions for file and directory names
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/24364) in GitLab 12.8.
Many common file systems have a [limit of 255 bytes for file and directory names](https://en.wikipedia.org/wiki/Comparison_of_file_systems#Limits), and while Git and GitLab both support paths exceeding those limits, the presence of them makes it impossible for users on those file systems to checkout a wiki repository locally.
To avoid this situation, these limits are enforced when editing pages through the GitLab web interface and API:
Many common file systems have a [limit of 255 bytes](https://en.wikipedia.org/wiki/Comparison_of_file_systems#Limits)
for file and directory names. Git and GitLab both support paths exceeding
those limits. However, if your file system enforces these limits, you cannot check out a
local copy of a wiki that contains filenames exceeding this limit. To prevent this
problem, the GitLab web interface and API enforce these limits:
- 245 bytes for page titles (reserving 10 bytes for the file extension).
- 255 bytes for directory names.
Please note that:
Non-ASCII characters take up more than one byte.
- Non-ASCII characters take up more than one byte.
- It's still possible to create files and directories exceeding those limits locally through Git, but this might break on other people's machines.
While you can still create files locally that exceed these limits, your teammates
may not be able to check out the wiki locally afterward.
## Edit a wiki page
You need Developer [permissions](../../permissions.md) or higher to edit a wiki page.
To do so:
You need Developer [permissions](../../permissions.md) or higher to edit a wiki page:

1. Edit the content.
1. Select **Save changes**.
### Create a table of contents
To generate a table of contents from the headings in a Wiki page, use the `[[_TOC_]]` tag.
For an example, see [Table of contents](../../markdown.md#table-of-contents).
To generate a table of contents from a wiki page's subheadings, use the `[[_TOC_]]` tag.
For an example, read [Table of contents](../../markdown.md#table-of-contents).
## Delete a wiki page
You need Maintainer [permissions](../../permissions.md) or higher to delete a wiki page.
To do so:
You need Maintainer [permissions](../../permissions.md) or higher to delete a wiki page:
1. Open the page you want to delete.
1. Go to the page for your project or group.
1. In the left sidebar, select **Wiki**, and go to the page you want to delete.
1. Select **Delete page**.
1. Confirm the deletion.

1. Add the new path to the **Title** field.
1. Select **Save changes**.
For example, if you have a wiki page called `about` under `company` and you want to
move it to the wiki's root:
1. Select the edit icon (**{pencil}**).
1. Change the **Title** from `about` to `/about`.
1. Select **Save changes**.
If you want to do the opposite:
You need Developer [permissions](../../permissions.md) or higher to move a wiki page:

## View list of all wiki pages
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/17673/) in GitLab 13.5, wiki pages are displayed as a nested tree in the sidebar and pages overview.
Every wiki has a sidebar from which a short list of the created pages can be
found. The list is ordered alphabetically.
![Wiki sidebar](img/wiki_sidebar_v13_5.png)
If you have many pages, not all are listed in the sidebar. Select
**View All Pages** to see all of them.
## View history of a wiki page
The changes of a wiki page over time are recorded in the wiki's Git repository,
and you can view them by selecting **Page history**.

From the history page you can see the revision of the page (Git commit SHA), its
author, the commit message, and when it was last updated.
To see how a previous version of the page looked like, select a revision
number in the **Page version** column.
From the history page you can see:

> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/23109) in GitLab 13.8, the sidebar can be customized by selecting the **Edit sidebar** button.
To customize the Wiki's navigation sidebar, you need Developer permissions to the project.
You need Developer [permissions](../../permissions.md) or higher to customize the wiki
navigation sidebar. This process creates a wiki page named `_sidebar` which fully
replaces the default sidebar navigation:
