-# How to Use
+![Light](./docs/demo.jpg)
+
+## How to Use
+
+### Installation
 
-## Installation
 ```bash
-dotnet add package Semi.Avalonia --version 0.1.0-preview5
+dotnet add package Semi.Avalonia --version 11.0.7
 ```
+
 Include Semi Design Styles in application:
 
 ```xaml
 <Application.Styles>
-    <StyleInclude Source="avares://Semi.Avalonia/Themes/DarkTheme.axaml" />
+    <StyleInclude Source="avares://Semi.Avalonia/Themes/Index.axaml" />
 </Application.Styles>
 ```
 
-That's all. 
+That's all.
+
+ColorPicker, DataGrid and TreeDataGrid are distributed in separated packages. Please install if you need.
+
+```bash
+dotnet add package Semi.Avalonia.ColorPicker --version 11.0.7
+dotnet add package Semi.Avalonia.DataGrid --version 11.0.7
+dotnet add package Semi.Avalonia.TreeDataGrid --version 11.0.7
+```
+
+```xaml
+<Application.Styles>
+    <StyleInclude Source="avares://Semi.Avalonia.ColorPicker/Index.axaml" />

+</ItemGroup>
+```
+
+The contents of the rd.xml file should be as follows:
+
+```xml
+<?xml version="1.0" encoding="utf-8"?>
+<Directives>
+    <!--
+        This file is part of RdXmlLibrary project.
+        Visit https://github.com/kant2002/rdxmllibrary for latest version.
+        If you have modifications specific to this Nuget package,
+        please contribute back.

+[English](./README.md)
+
+Avalonia UI 控件主题，灵感来自 Semi Design
+
+如果您希望使用更多的拓展控件，欢迎尝试 [Ursa](https://github.com/irihitech/Ursa.Avalonia)
+
+![Light](./docs/demo.jpg)
+
+## 如何使用
+
+### 安装
+
+```bash
+dotnet add package Semi.Avalonia --version 11.0.7
+```
+
+在样式中引用 Semi 主题：
+
+```xaml
+<Application.Styles>
+    <StyleInclude Source="avares://Semi.Avalonia/Themes/Index.axaml" />
+</Application.Styles>
+```
+
+这样就可以了。
+
+ColorPicker， DataGrid 和 TreeDataGrid 的样式单独分发，如果需要请安装并引用。
+
+```bash
+dotnet add package Semi.Avalonia.ColorPicker --version 11.0.7
+dotnet add package Semi.Avalonia.DataGrid --version 11.0.7
+dotnet add package Semi.Avalonia.TreeDataGrid --version 11.0.7
+```
+
+```xaml
+<Application.Styles>
+    <StyleInclude Source="avares://Semi.Avalonia.ColorPicker/Index.axaml" />
+    <StyleInclude Source="avares://Semi.Avalonia.DataGrid/Index.axaml" />
+    <StyleInclude Source="avares://Semi.Avalonia.TreeDataGrid/Index.axaml" />
+</Application.Styles>
+```
+
+如果需要进行 AOT 发布，则需要在项目中包含 rd.xml 文件：
+
+```xml
+<ItemGroup>
+    <RdXmlFile Include="rd.xml"/>
+</ItemGroup>
+```
+
+rd.xml 文件的内容如下：
+
+```xml
+<?xml version="1.0" encoding="utf-8"?>
+<Directives>
+    <!--
+        This file is part of RdXmlLibrary project.
+        Visit https://github.com/kant2002/rdxmllibrary for latest version.
+        If you have modifications specific to this Nuget package,
+        please contribute back.
+    -->
+    <Application>
+        <Assembly Name="Avalonia.Markup.Xaml" Dynamic="Required All"/>
+        <Assembly Name="Semi.Avalonia" Dynamic="Required All"/>
+        <!-- If you don't use these, please don't include them.
+            <Assembly Name="Semi.Avalonia.DataGrid" Dynamic="Required All"/>
+            <Assembly Name="Semi.Avalonia.ColorPicker" Dynamic="Required All"/>
+        -->
+    </Application>

+# DRM启动步骤
+
+(Ubuntu18.04Server版本 虚拟机测试OK)  
+(Orange Pi Zero2 Ubuntu20.04-arm64 测试OK)
+
+Avalonia官方参考文档：https://docs.avaloniaui.net/docs/next/guides/platforms/rpi/running-on-raspbian-lite-via-drm
+
+1.Linux端运行命令  
+```
+sudo apt update  
+sudo apt upgrade  
+sudo reboot  
+sudo apt - get install libgbm1 libgl1 - mesa - dri libegl1 - mesa libinput10
+```
+
+2.安装测试工具测试(出现一个彩色立方体说明环境安装完成)  
+```
+sudo apt-get install kmscube
+sudo kmscube
+```
+
+3.安装.net运行时(参考网址：https://learn.microsoft.com/zh-cn/dotnet/core/install/linux?WT.mc_id=dotnet-35129-website)
+
+4.新建一个Avalonia项目，nuget里面添加Avalonia.LinuxFramebuffer包
+
+5.添加StartLinuxDrm代码(不知道怎么添加看Semi.Avalonia.Demo.Drm项目代码)
+
+6.发布程序到Linux(安装.net，怎么运行这些省略)
+            
+7.运行 ./Semi.Avalonia.Demo.Drm --drm
+
+## 报错处理：
+
+1. 报错内容

+
+ 解决方法：
+>如果使用Semi发布文件不要裁剪，如果裁剪会报错
+         
+
+2. 报错内容

+
+解决方法：
+>`program.cs`的显卡路径错误，可能不是`dev/dri/card1`，看在`dev/dri`目录下有无其他的显卡如`card0`。
