+```
+allprojects {
+    repositories {
+        google()
+        jcenter()
+        maven { url 'https://jitpack.io' }
+    }
+}
+```
+
+You can use the custom view in following manner:
+
+#### In XML:
+
+```
+  <com.phappytech.customseekbarandroid.CustomSeekBar
+        android:id="@+id/custom"
+        android:layout_width="wrap_content"
+        android:layout_height="wrap_content"
+        android:padding="5dp"
+        app:arrowColor="@color/colorAccent"
+        app:borderColor="@color/colorPrimary"
+        app:showArrows="true"
+        app:showDummyData="true"
+        app:showProgressOnOnClick="false"
+        app:showText="true"
+        app:textColor="@color/colorPrimary"
+        app:textPadding="10dp"
+        app:textSize="14sp" />
+        
+```
+
+And the values can be passed in you activity class using:
+
+```
+ArrayList<ProgressSegment> progressSegments = new ArrayList<>();
+        int[] colors = {Color.RED, Color.GREEN, Color.BLUE, Color.GRAY, Color.YELLOW};
+        for (int i = 0; i < 5; i++) {
+            ProgressSegment progressSegment = new ProgressSegment(Parcel.obtain());
+            progressSegment.name = "progress" + i;
+            progressSegment.progress = (i + 3) * 10;
+            progressSegment.color = colors[i];
+            progressSegments.add(progressSegment);
+        }
+        CustomSeekBar customSeekBar = findViewById(R.id.custom);
+        customSeekBar.setProgressSegments(progressSegments);
+```
+
+The clickListener to handle clicks on segment can be used as:
+
+```
+        customSeekBar.setSegmentClickedListener(new SegmentClickedListener() {
+            @Override
+            public void onClickSegment(int pos) {
+                Toast.makeText(MainActivity.this, "seg: " + pos, Toast.LENGTH_SHORT).show();
+            }
+        });
+```
