Restructure documentation. Now the documentation has installation, administration, usage, development, contributing the 5 main parts (#23629)
- **Installation**: includes how to install Gitea and related other
tools, also includes upgrade Gitea
- **Administration**: includes how to configure Gitea, customize Gitea
and manage Gitea instance out of Gitea admin UI
- **Usage**: includes how to use Gitea's functionalities. A sub
documentation is about packages, in future we could also include CI/CD
and others.
- **Development**: includes how to integrate with Gitea's API, how to
develop new features within Gitea
- **Contributing**: includes how to contribute code to Gitea
repositories.

After this is merged, I think we can have a sub-documentation of `Usage`
part named `Actions` to describe how to use Gitea actions

# Container Registry
Publish [Open Container Initiative](https://opencontainers.org/) compliant images for your user or organization.
The container registry follows the OCI specs and supports all compatible images like [Docker](https://www.docker.com/) and [Helm Charts](https://helm.sh/).
**Table of Contents**
{{< toc >}}
## Requirements
To work with the Container registry, you can use the tools for your specific image type.
The following examples use the `docker` client.
## Login to the container registry
To push an image or if the image is in a private registry, you have to authenticate:
```shell
docker login gitea.example.com
```
If you are using 2FA or OAuth use a [personal access token]({{< relref "doc/development/api-usage.en-us.md#authentication" >}}) instead of the password.
## Image naming convention
Images must follow this naming convention:
`{registry}/{owner}/{image}`
For example, these are all valid image names for the owner `testuser`:
`gitea.example.com/testuser/myimage`
`gitea.example.com/testuser/my-image`
`gitea.example.com/testuser/my/image`
**NOTE:** The registry only supports case-insensitive tag names. So `image:tag` and `image:Tag` get treated as the same image and tag.
## Push an image
Push an image by executing the following command:
```shell
docker push gitea.example.com/{owner}/{image}:{tag}
```
| Parameter | Description |
| ----------| ----------- |
| `owner` | The owner of the image. |
| `image` | The name of the image. |
| `tag` | The tag of the image. |
For example:
```shell
docker push gitea.example.com/testuser/myimage:latest
```
## Pull an image
Pull an image by executing the following command:
```shell
docker pull gitea.example.com/{owner}/{image}:{tag}
```
| Parameter | Description |
| ----------| ----------- |
| `owner` | The owner of the image. |
| `image` | The name of the image. |
| `tag` | The tag of the image. |
For example:
```shell
docker pull gitea.example.com/testuser/myimage:latest
```
