+.SYNOPSIS
+Build this repository
+
+.DESCRIPTION
+Downloads korebuild if required. Then builds the repository.
+
+.PARAMETERPath
+The folder to build. Defaults to the folder containing this script.
+
+.PARAMETERChannel
+The channel of KoreBuild to download. Overrides the value from the config file.
+
+.PARAMETERDotNetHome
+The directory where .NET Core tools will be stored.
+
+.PARAMETERToolsSource
+The base url where build tools can be downloaded. Overrides the value from the config file.
+
+.PARAMETERUpdate
+Updates KoreBuild to the latest version even if a lock file is present.
+
+.PARAMETERConfigFile
+The path to the configuration file that stores values. Defaults to version.xml.
+
+.PARAMETERMSBuildArgs
+Arguments to be passed to MSBuild
+
+.NOTES
+This function will create a file $PSScriptRoot/korebuild-lock.txt. This lock file can be committed to source, but does not have to be.
+When the lockfile is not present, KoreBuild will create one using latest available version from $Channel.
+
+The $ConfigFile is expected to be an XML file. It is optional, and the configuration values in it are optional as well.
+
+.EXAMPLE
+Example config file:
+```xml
+<!-- version.xml -->
+<Project>
+ <PropertyGroup>
+ <KoreBuildChannel>dev</KoreBuildChannel>
+ <KoreBuildToolsSource>https://aspnetcore.blob.core.windows.net/buildtools</KoreBuildToolsSource>
+ </PropertyGroup>
+</Project>
+```
