+Simple Java Library for getting information about the current playback from the windows system media transport controls (SMTC).
+
+## Usage
+Load the native library
+```java
+SMTC4J.load();
+```
+
+Start the automatic update thread
+
+```java
+long updateIntervalMillis = 500; // e.g., update every 500ms
+SMTC4J.startUpdateThread(updateIntervalMillis);
+```
+
+Access the cached information
+
+Media info (title, artist, album, duration, cover, source app):
+```java
+MediaInfo mediaInfo = SMTC4J.getCachedMediaInfo();
+System.out.println("Title: " + mediaInfo.getTitle());
+```
+
+Playback state (play/pause/stop code, position in seconds):
+
+```java
+PlaybackState playbackState = SMTC4J.getCachedPlaybackState();
+System.out.println("State code: " + playbackState.getStateCode());
+System.out.println("Position: " + playbackState.getPosition());
+```
