+# WixToolset.BootstrapperApplications.wixext - Bootstrapper Applications WiX Toolset Extension
-WixToolset.BootstrapperApplications.wixext - Bootstrapper Applications WiX Toolset Extension
+This WiX Extension provides the standard BootstrapperApplications provided by the WiX Toolset.
+- WixStdBA ([WixStandardBootstrapperApplication](https://docs.firegiant.com/wix/schema/bal/wixstandardbootstrapperapplication/)), a bootstrapper application with support for custom themes
+- WixIuiBA ([WixInternalUIBootstrapperApplication](https://docs.firegiant.com/wix/schema/bal/wixinternaluibootstrapperapplication/)), a bootstrapper application for showing internal UI of Windows Installer packages
+- WixPreqBA ([WixPrerequisiteBootstrapperApplication](https://docs.firegiant.com/wix/schema/bal/wixprerequisitebootstrapperapplication/)), a secondary bootstrapper application for bootstrapping the prerequisites needed for a primary bootstrapper application
+[Web Site][web] | [Documentation][docs] | [Issue Tracker][issues] | [Discussions][discussions]
+## Open Source Maintenance Fee
+To ensure the long-term sustainability of this project, users of this package who generate revenue must pay an [Open Source Maintenance Fee][osmf]. While the source code is freely available under the terms of the [LICENSE][license], this package and other aspects of the project require [adherence to the Open Source Maintenance Fee EULA][eula].
+To pay the Maintenance Fee, [become a Sponsor](https://github.com/sponsors/wixtoolset).
+## Getting started
+Add the WiX Extension as a PackageReference to your .wixproj:
+```
+<Project Sdk="WixToolset.Sdk/7.0.0">
+  <ItemGroup>
+    <PackageReference Include="WixToolset.BootstrapperApplications.wixext" Version="7.0.0" />
+  </ItemGroup>
+</Project>
+```
+Then add the namespace and bootstrapper application of choice:
+```
+<Wix xmlns="http://wixtoolset.org/schemas/v4/wxs"
+     xmlns:bal="http://wixtoolset.org/schemas/v4/wxs/bal">
+  <Bundle BundleId="AcmeCorp.Example" Name="Example Bundle" Version="0.0.0.1" Manufacturer="ACME Corporation">
+    <BootstrapperApplication>
+      <bal:WixStandardBootstrapperApplication LicenseUrl="http://wixtoolset.org/about/license/" Theme="hyperlinkLicense" />
+    </BootstrapperApplication>
+  </Bundle>
+</Wix>

+To ensure the long-term sustainability of this project, users of this package who generate revenue must pay an [Open Source Maintenance Fee][osmf].

+## Getting started
 BAFunctions are native-code DLLs (typically written in C++) that let you supplement the behavior of WixStdBA, rather than writing an entirely new BA to tweak existing BA behavior.
-## Sources
+The best way to learn is via the samples at: https://github.com/wixtoolset/wix/tree/HEAD/src/ext/Bal/Samples/bafunctions

+## Getting started
+Add the WiX Extension as a PackageReference to your .wixproj:
+```
+<Project Sdk="WixToolset.Sdk/7.0.0">
+  <ItemGroup>
+    <PackageReference Include="WixToolset.Util.wixext" Version="7.0.0" />
+  </ItemGroup>
+</Project>
+```
+Then add the extension's namespace:
+```
+<Wix xmlns="http://wixtoolset.org/schemas/v4/wxs"
+     xmlns:util="http://wixtoolset.org/schemas/v4/wxs/util">
+  ..
+</Wix>
