+## Q. Can I use this library with API level 8?
+
+### A. It's not supported, but you can.
+
+By adding `tools:overrideLibrary` to `<uses-sdk>` tag,
+you can build this library with `android:minSdkVersion="8"`.
+
+```xml
+<manifest xmlns:android="http://schemas.android.com/apk/res/android"
+    xmlns:tools="http://schemas.android.com/tools"
+    package="com.example.app">
+
+    <uses-sdk
+        android:minSdkVersion="8"
+        android:targetSdkVersion="22"
+        tools:overrideLibrary="com.github.ksoichiro.android.observablescrollview" />
+```
+
+If you have other libraries to override, separate them with comma.
+
+```xml
+<manifest xmlns:android="http://schemas.android.com/apk/res/android"
+    xmlns:tools="http://schemas.android.com/tools"
+    package="com.example.app">
+
+    <uses-sdk
+        android:minSdkVersion="8"
+        android:targetSdkVersion="22"
+        tools:overrideLibrary="com.melnykov.fab,com.github.ksoichiro.android.observablescrollview" />
