+# Using the Extras Sdk
+
+## Migrate from previous versions
+
+If you're using v1.6+ of the Extras SDK, then you would know that few properties have been changed, and the help is provided as a warning to use the new property names.
+
+If you're not using the new version, and/or wish to migrate your build system to support this version, here are the instructions to do just that:
+
+0. BACK UP! BACK UP! (if you're not using version control)
+
+1. First remove any workarounds (check the closed issues first) that you've applied using the previous Extras SDK version.
+
+2. If you're using Visual Studio IDE v15.6+ (if you can update, then update) and use SDK style.
+
+Your project diff:
+
+```diff
+- <Project Sdk="Microsoft.NET.Sdk">
++ <Project Sdk="MSBuild.Sdk.Extras">
+  <!-- OTHER PROPERTIES -->
+  <PropertyGroup>
+    <TargetFrameworks>net46;uwp10.0;tizen40</TargetFrameworks>
+  </PropertyGroup>
+
+  <ItemGroup>
+-    <PackageReference Include="MSBuild.Sdk.Extras" Version="1.6.0" PrivateAssets="All"/>
+  <!-- OTHER PACKAGES/INCLUDES -->
+  </ItemGroup>
+
+-  <Import Project="$(MSBuildSdkExtrasTargets)" Condition="Exists('$(MSBuildSdkExtrasTargets)')"/>
+  <!-- OTHER IMPORTS -->
+</Project>
+```
+
+```diff
+- PackageReference style
++ SDK style
+```
+
+More info: [ReadMe](../README.md)
+
+3. Remove any UWP/Tizen package referneces as they are implicitly included if you're using SDK style.
+
+4. Rename these properties to the new ones
+
+### User facing properties
+
+| OLD Property                                    | NEW Property/Behaviour                                             |

+| `ExtrasImplicitPlatformPackageIsPrivate`        | Auto set for library like items                                    |
+| `EmbeddedResourceGeneratorVisibilityIsInternal` | opposite of `EmbeddedResourceGeneratedCodeIsPublic`                |
+
+5. If you're using it for WinForms/WPF, you can set `EnableWpfProjectSetup`/`EnableWinFormsProjectSetup` to `true` to include required references and default items.
+
+6. That's it you're done! If you find any issues during build, check with the [Templates/TestProjects](../TestProjects) included and create an issue if that doesn't help.
