+
+## Toolbar
+Toolbar is alternative implementation of Toolbar component on Android.
+
+# Installation
+ - To implement **Toolbar** to your Android project via Gradle, you need to add JitPack repository to your root build.gradle.
+```gradle
+allprojects {
+    repositories {
+        ...
+        maven { url 'https://jitpack.io' }
+    }
+}
+```
+ - After adding JitPack repository, you can add **Toolbar** dependency to your app level build.gradle.
+```gradle
+dependencies {
+    implementation "com.trendyol.ui-components:toolbar:$toolbarVersion"
+}
+```
+:warning: To use **Toolbar**, you have to enable dataBinding from your main project.
+
+# Usage
+
+To customize **Toolbar** you can provide `ToolbarViewState` or use attributes listed below. All text attributes can be HTML formatted, **Toolbar** will style them.
+
+| Attribute | Description | Default Value | Sample Usage |
+| ------------- | ------------- | ------------- | ------------- |
+| `app:leftImageDrawable` | Left image drawable resource. | ic_arrow_back | `app:leftImageDrawable="@drawable/ic_back"` |
+| `app:middleImageDrawable` | Middle image drawable resource. | 0 | `app:middleImageDrawable="@drawable/ic_logo"` |
+| `app:rightImageDrawable` | Right image drawable resource. | 0 | `app:rightImageDrawable="@drawable/ic_close"` |
+| `app:upperLeftText` | Upper left text resource. | null | `app:upperLeftText="@string/list_title"` |
+| `app:lowerLeftText` | Lower left text resource. If upper left text is set and this is not set, upper left text would be centered vertically. | null | `app:lowerLeftText="@string/list_item_description"` |
+| `app:middleText` | Middle text resource. | null | `app:middleText="@string/app_name"` |
+| `app:upperRightText` | Upper right text resource. | null | `app:upperRightText="@string/action_select_all"` |
+| `app:lowerRightText` | Lower right text resource. If upper left text is set and this is not set, upper left text would be centered vertically. | null | `app:lowerRightText="@string/action_clear"` |
+| `app:toolbarBackground` | Background color or drawable resource. | android.R.color.white | `app:toolbarBackground="@drawable/toolbar_background"` |
+
+Sample usage with attributes:
+
+```xml
+
+    <com.trendyol.uicomponents.toolbar.Toolbar
+        android:id="@+id/toolbar"
+        android:layout_width="match_parent"
+        android:layout_height="?attr/actionBarSize"
+        app:toolbarBackground="@color/background"
+        app:middleText="@string/app_name"
+        app:upperRightText="@string/clear_all"/>
+
+```
+
+With `ToolbarViewState` you can also provide TextAppearance resources for all text fields in **Toolbar**.
+
+You can assign every text field and image to click listeners.
+
+To set click listener, you can use **Toolbar** instance fields like below.
+
+```kotlin
+
+    val toolbar: Toolbar = findViewById(R.id.toolbar)
+
+    toolbar.leftImageClickListener = { onBackPressed() }
+
+```
+
+Sample usage with `ToolbarViewState`:
+
+```kotlin
+
+    val toolbar: Toolbar = findViewById(R.id.toolbar)
+
+    toolbar.viewState = ToolbarViewState(
+        upperLeftText = "<b>List</b>",
+        leftImageDrawableResId = R.drawable.ic_arrow_back,
+        upperLeftTextAppearance = R.style.MyTextStyle_Body_2
+    )
+
+```
