# Update Manager Reference
## Basic Updating
The "Easy Mode" method that does everything all in one go.
* `UpdateApp` - downloads and updates the app to the latest version.
## Advanced Updating
The following methods are provided to allow you to have more control of the update process (i.e., to interact with app updates and apply them if desired).
* `CheckForUpdate` - checks on the server if there are updates available. Returns an `UpdateInfo` object that contains information about any pending updates.
* `DownloadReleases` - downloads release files (the `nupkg` file deltas) from the server to the local machine
* `ApplyReleases` - installs the downloaded packages, and returns the new `app-[version]` directory path.
### UpdateInfo
The `UpdateInfo` class contains information about available and installed releases.
~~~cs
public class UpdateInfo
{
public ReleaseEntry CurrentlyInstalledVersion;
public ReleaseEntry FutureReleaseEntry;
public List<ReleaseEntry> ReleasesToApply;
}
~~~
### ReleaseEntry
The `ReleaseEntry` class contains the specifics of each release.
~~~cs
public interface ReleaseEntry
{
public string SHA1;
public string Filename;
public long Filesize;
public bool IsDelta;
}
~~~
