-## Generating a custom color palette and export as DSP file
+It is possible to configure the import process. The _UnoDspImportColors_ item found in the _csproj_ file has a number of attributes we can set:
+
+| Attribute      | Description                     | Default Value           |
+|----------------|---------------------------------|-------------------------|
+| `Include`      | Style files to input            |                         |
+| `Generator`*   | Type of generator to use        | `xaml`                  |
+| `OutputPath`   | Path to use for the output      | Input file directory    |
+
+\* The possible values for Generator are `xaml` and `csharp`.
+
+```xml
+<ItemGroup>
+   <UnoDspImportColors Include="Styles\*.json" Generator="csharp" OutputPath="json_file.g.cs"  />
+</ItemGroup>
+```
+
+> [!NOTE]
+> The Uno.Sdk will automatically include this configuration for you. Creating a new project with the _CSharpMarkup_ feature will automatically set the generator attribute to _csharp_. It will set the generator to _xaml_ by default.

-4. Replace the file `ColorPaletteOverride.zip` in the `Styles` folder of your application project with the one you just downloaded.
-5. Build your application. The `ColorPaletteOverride.xaml` file will be automatically updated with the colors present in the DSP zip file.

 ## More flexibility
 
-This will generate the file at each build, potentially overriding any changes you made to the file. If you want to keep it that way, you can simply remove the `ColorPaletteOverride.zip` file from the `Styles` folder, the file won't get overwritten anymore.

 Alternatively, you can also use the [Uno.Dsp.Cli](https://nuget.org/packages/Uno.Dsp.Cli) package to generate the file from the command line. This will allow you to generate the file only when you want to, and not at each build.
+
+> [!NOTE]
+> Although the **Material Theme Builder Tool** doesn't export **Material Tokens (DSP)** packages anymore, the Uno Figma Plugin still supports this file format.
+> To be able to import DSP packages just follow the same steps described previously and save the downloaded DSP zip file as `ColorPaletteOverride.zip` in the `Styles` folder of your application project.
+> In that case, make sure to delete the `material-theme.json` file from `Styles` folder before building your application, to avoid conflicts.
