A [wiki](https://en.wikipedia.org/wiki/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 repo 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 repo in your repository with a predefined name in the form of `<your-repository-name>.wiki.git`.
|
|
|
|
It consists of [Markdown](https://en.wikipedia.org/wiki/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.
|
|
|
|
|
|
|
|
Clicking on the "Insert Image" button will make the following text appear in your text editor: ``
|
|
|
|
## Adding content using a local Git client
|
|
|
|
You can work with the wiki repo as you would with any other Git repo on Forgejo.
|
|
|
|
```shell
|
|
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:
|
|
|
|
```shell
|
|
# 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**:
|
|
|
|
```markdown
|
|
|
|
```
|
|
|
|
**External image**:
|
|
|
|
```markdown
|
|
|
|
```
|
|
|
|
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.
|
|
|
|
## Adding a sidebar and a footer
|
|
|
|
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:
|
|
|
|
```markdown
|
|
- [[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`
