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

Migration Features

Complete migrations were introduced in Gitea 1.9.0. It defines two interfaces to support migrating repository data from other Git host platforms to Gitea or, in the future, migrating Gitea data to other Git host platforms.

Currently, migrations from GitHub, GitLab, and other Gitea instances are implemented.

First of all, Gitea defines some standard objects in packages modules/migration. They are Repository, Milestone, Release, ReleaseAsset, Label, Issue, Comment, PullRequest, Reaction, Review, ReviewComment.

Downloader Interfaces

To migrate from a new Git host platform, there are two steps to be updated.

  • You should implement a Downloader which will be used to get repository information.
  • You should implement a DownloaderFactory which will be used to detect if the URL matches and create the above Downloader.
    • You'll need to register the DownloaderFactory via RegisterDownloaderFactory on init().

You can find these interfaces in downloader.go.

Uploader Interface

Currently, only a GiteaLocalUploader is implemented, so we only save downloaded data via this Uploader to the local Gitea instance. Other uploaders are not supported at this time.

You can find these interfaces in uploader.go.
