 ## 安装教程
 
 
-1. 在主项目entry中的grade文件依赖
+1.在项目根目录下的build.gradle文件中，
+```
+allprojects {
+   repositories {
+       maven {
+           url 'https://s01.oss.sonatype.org/content/repositories/snapshots/'
+       }
+   }
+}
+```
+2.在entry模块的build.gradle文件中，
 ```
 dependencies {
-    implementation fileTree(dir: 'libs', include: ['*.jar', '*.har'])
-     implementation project(path: ':library')
+   implementation('com.gitee.chinasoft_ohos:PermissionUtils:0.0.1-SNAPSHOT')
+   ......  
 }
 ```
 如无法运行，删除项目.gradle,.idea,build,gradle,build.gradle文件，
