-#### 支持方法
-方法一
+### 依赖导入
 
-```java
-PermissionManager.request(Fragment fragment, PermissionCallback callback, String... permissions)
+项目根目录
+
+``` gradle
+allprojects {
+	repositories {
+		...
+		maven { url 'https://jitpack.io' }
+	}
+}
 ```
 
-方法二
+模块目录
 
-```java
-PermissionManager.request(Context context, PermissionCallback callback, String... permissions)
+``` gradle
+dependencies {
+	implementation 'com.github.dimeno-tech:dimeno-permission:0.0.2'
+}
 ```
 
-方法三
+### 接口说明
 
-```java
-PermissionManager.request(FragmentActivity activity, PermissionCallback callback, String... permissions)
-``` 
+为简便接口，可使用抽象接口实现类 **AbsPermissionCallback**
 
-#### 接口说明
 ```java
 public interface PermissionCallback {

-#### 使用方式
+### 代码示例
+
+```java
+public final class PermissionManager {
+    public static void request(Fragment fragment, PermissionCallback callback, String... permissions);
+    public static void request(Context context, PermissionCallback callback, String... permissions);
+    public static void request(FragmentActivity activity, PermissionCallback callback, String... permissions);
+    public static Intent getSettingIntent(Context context);

+```
+
 ```java
 PermissionManager.request(this, new PermissionCallback() {
