Integrated Wiki

A wiki is a collaborative space on the web. It is a common practice to use wikis to collect knowledge and share information.
Codeberg allows you to add a wiki to a repository for additional documentation.

The user in these examples is knut, the polar bear and its repository is foobar.

Activation and Permissions

To enable the wiki for a repository, visit the Settings page and activate Enable Repository Wiki in the Advanced Section. It will default to the built-in wiki which is described here, but you can add an URI to an external site the “Wiki” tab should link to.

Warning
Be aware that the wiki, once enabled, is accessible for everyone who has read access to your repository - on public repositories even unauthenticated guests can access the wiki.
The wiki is not a suitable place for storing private information or secrets (like passwords).

Activating the Allow anyone to edit the Wiki option in Settings will give everyone with an account write access to the wiki.

To edit the wiki write permission to the repository is required, unless the Allow anyone to edit the Wiki setting is activated on the Settings page, in the Advanced Settings section.

Wiki structure

The wiki is essentially a separate Git repository in your repository with a predefined name in the form of <your-repository-name>.wiki.git.

It consists of Markdown files (file extension .md) and additional assets like images.
No further stylesheets are needed. The Markdown files are automatically rendered according to the selected Forgejo theme.

Adding content via web

After you have enabled the wiki you are prompted to create the initial page Home.md.

The web UI in your browser is currently limited to adding, updating, and deleting pages; you can’t manage assets like images this way.

Wiki home page with edit buttons

Clicking on the “Insert Image” button will make the following text appear in your text editor: ![](https://)

Adding content using a local Git client

You can work with the wiki repository as you would with any other Git repository on Forgejo.

git clone git@codeberg.org:knut/foobar.wiki.git
cd foobar.wiki
nano Home.md # or your editor of choice
git commit -am "create Home page"

Editing locally allows you to use your favorite editor (preferably with Markdown syntax check and highlighting) and manage additional assets like images.

Adding images using a local Git client

You can add images to the root directory or a specific subfolder (like assets or images) using your local Git client.

A feasible workflow might look like this:

# create a subfolder for images
mkdir images
cd images
# copy the image into this folder
git add images/image.png
git commit -m "add image"
git push

Attaching images in Markdown documents

Now, you can reference the image in Markdown, like this:

File in repository:

![image alt text](images/image.png 'image title')

External image:

![image alt text](https://example.com/image.jpg 'image title')

When including images from Forgejo repositories, keep in mind that you should use the raw version of the image.

After saving your changes, the image should be visible.

In contrast to embedding external images, images in Git are only rendered after saving the wiki or Markdown file changes.

To enhance the usability of your wiki you can add a custom sidebar and a footer that are shown on every page. The sidebar will be displayed to the right of the main content and the footer below.

To enable the sidebar, just add a file named _Sidebar.md to your wiki. For a footer the file must be named _Footer.md. Both file types allow common Markdown syntax to adjust the presentation to your needs.

Very basic example for a sidebar:

- [[Home]]

### Content

- [Page 1](./Page-1/)

> knuts wiki

These files starting with _ are hidden, so in the web UI you need to manually browse for the files. E.g. for our user knut and his foobar repo:
https://codeberg.org/knut/foobar/wiki/_Sidebar
