#### Offline installation

By default, the installer will download content from the official Scoop Git repos.
For a full offline installation you can pre-download the following files:

- https://github.com/ScoopInstaller/Scoop/archive/master.zip as `ScoopInstaller-Scoop.zip`
- https://github.com/ScoopInstaller/Main/archive/master.zip as `ScoopInstaller-Main.zip`

And then run:

```shell
# From a local folder
.\install.ps1 -OfflineSourceFolder 'C:\Local\Path\To\Zip\Files'

# From a network path
.\install.ps1 -OfflineSourceFolder '\\UNC\Path\To\Zip\Files'
```

The installer will copy/extract the provided ZIP files as needed. They are not deleted afterwards.

### Silent Installation

You can redirect all outputs to Out-Null or a log file to silence the installer. And you can use `$LASTEXITCODE` to check the installation result, it will be `0` when the installation success.
