+# ExoPlayer RTMP Extension #
+
+## Description ##
+
+The RTMP Extension is an [DataSource][] implementation for playing [RTMP][] streaming using
+[Librtmp Client for Android].
+
+## Using the extension ##
+
+When building [MediaSource][], inject `RtmpDataSourceFactory` like this:
+
+```java
+private MediaSource buildMediaSource(Uri uri, String overrideExtension) {
+  int type = TextUtils.isEmpty(overrideExtension) ? Util.inferContentType(uri)
+      : Util.inferContentType("." + overrideExtension);
+  switch (type) {
+
+    // ... other types cases
+
+    case C.TYPE_OTHER:
+      DataSource.Factory factory = uri.getScheme().equals("rtmp") ? new RtmpDataSourceFactory() : mediaDataSourceFactory;
+      return new ExtractorMediaSource(uri, factory, new DefaultExtractorsFactory(), mainHandler, eventLogger);
+    default: {
+      throw new IllegalStateException("Unsupported type: " + type);
+    }
+  }
+}
+```
