-[Download Demo](https://github.com/2dxgujun/AndroidTagGroup/releases/download/v1.4/AndroidTagGroup-Demo-v1.4.apk)
-
-# Usage
-
-## Step 1
-
-#### Gradle
-```groovy
-dependencies {
-   compile 'me.gujun.android.taggroup:library:1.4@aar'
-}
-```
-
-#### Maven
-```xml
-<dependency>
-    <groupId>me.gujun.android.taggroup</groupId>
-    <artifactId>library</artifactId>
-    <version>1.4</version>
-    <type>apklib</type>
-</dependency>
-```
-
-## Step 2
+## Usage
+### Step 1
+Follow [these steps](https://jitpack.io/#alirezaaa/AndroidTagGroup/v1.4).
 
+### Step 2
 Use it in your own code:
 ```xml
-<me.gujun.android.taggroup.TagGroup
-    android:id="@+id/tag_group"
-    style="@style/TagGroup" />
+<me.gujun.android.taggroup.AndroidTagGroup
+    android:id="@+id/androidTagGroup"
+    style="@style/AndroidTagGroup" />
 ```
 
 ```java
-TagGroup mTagGroup = (TagGroup) findViewById(R.id.tag_group);
-mTagGroup.setTags(new String[]{"Tag1", "Tag2", "Tag3"});
+TagGroup mTagGroup = (TagGroup) findViewById(R.id.androidTagGroup);
+mTagGroup.setTags(new String[]{"Tag 1", "Tag 2", "Tag 3"});
 ```
-Use `setTags(...)` to set the initial tags in the group.
-
-#### How to submit a new tag?
-
-To "submit" a new tag as user press "Enter" or tap the blank area of the tag group, also you can "submit" a new tag via `submitTag()`.
-
-**Note**: Google keyboard (a few soft keyboard not honour the key event) currently not supported "Enter" key to "submit" a new tag.
 
-#### How to delete a tag?
-
-To delete a tag as user press "Backspace" key or double-tap the tag which you want to delete.
-
-#### How to detect tag click event?
-
-Implement a callback interface: `TagGroup.OnTagClickListener`, and set the listener via `setOnTagClickListener()`.
-
-
-# Build
-
-run `./gradlew assembleDebug` (Mac/Linux)
-
-or
-
-run `gradlew.bat assembleDebug` (Windows)
+### Notes
+- Use `setTags(...)` to set the initial tags in the group.
+- To submit a new tag as user press "Enter" key or tap the blank area of the tag group, use `submitTag()`.
+- To delete a tag as user press "Backspace", double-tap the tag which you want to delete.
+- There are following interfaces to implement; `OnTagLimitationExceedListener`, `OnTagChangeListener`, and `OnTagClickListener`.
