+.DESCRIPTION
+Downloads korebuild if required. Then builds the repository.
+
+.PARAMETER Path
+The folder to build. Defaults to the folder containing this script.
+
+.PARAMETER Channel
+The channel of KoreBuild to download. Overrides the value from the config file.
+
+.PARAMETER DotNetHome
+The directory where .NET Core tools will be stored.
+
+.PARAMETER ToolsSource
+The base url where build tools can be downloaded. Overrides the value from the config file.
+
+.PARAMETER Update
+Updates KoreBuild to the latest version even if a lock file is present.
+
+.PARAMETER ConfigFile
+The path to the configuration file that stores values. Defaults to version.xml.
+
+.PARAMETER MSBuildArgs
+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>
