 ### Graph Settings options
 
 | Menu Item | Description |
 |:----------|:------------|
-| Precision | A [Precision Mode](Precision-Modes.md) drop-down menu that lets you set the default precision for the entire graph. You can override the Precision setting here at the node level in your graph.|
-| Preview Mode | (Subgraphs only) Your options are **Inherit**, **Preview 2D**, and **Preview 3D**. |
-| Active Targets | A list that contains the Targets you've selected. You can add or remove entries using the Add (**+**) and Remove (**-**) buttons. <br/>Shader Graph supports three targets: the [Universal Render Pipeline](https://docs.unity3d.com/Manual/urp/urp-introduction.html), the [High Definition Render Pipeline](https://docs.unity3d.com/Packages/[email protected]/manual/index.html), and [Built-In Render Pipeline](https://docs.unity3d.com/2020.3/Documentation/Manual/render-pipelines). Target-specific settings appear below the standard setting options. The displayed Target-specific settings change according to which Targets you select. |
+| **Precision** | Select **Single** or **Half** from the [Precision](Precision-Modes.md) dropdown menu as the graph's default Precision Mode for the entire graph. |
+| **Preview Mode** | Select your preferred preview mode for a node that has a preview from the following options: <ul><li>**Inherit**:  The Unity Editor automatically selects the preview mode to use.</li><li>**Preview 2D**: Renders the output of the Sub Graph as a flat two-dimensional preview.</li><li>**Preview 3D**: Renders the output of the Sub Graph on a three-dimensional object such as a sphere.</li></ul> This property is available only when you selected a [Sub Graph](Sub-graph.md).  |
+| **Active Targets** | A list that contains selected targets. You can add or remove **Active Targets** by selecting the **Add (+)** and **Remove (&minus;)** buttons, respectively. <br/>Shader Graph supports three targets: <ul><li>**Built-in**: Shaders for Unity’s [Built-In Render Pipeline](xref:um-render-pipelines).</li><li>**Custom Render Texture**: Shaders for updating [Custom Render Textures](Custom-Render-Texture.md). </li><li>**Universal**: Shaders for the [Universal Render Pipeline](xref:um-shaders-in-universalrp-reference).</li></ul> The available properties displayed depend on the targets you have added to the list. Refer to the [Shader Material Inspector window properties](xref:um-shaders-in-universalrp-reference) for the respective **Materials** you select for the **Built-in** and **Universal** targets.|
