 From a Python program, you can embed youtube-dl in a more powerful fashion, like this:
 
-    import youtube_dl
+```python
+import youtube_dl
 
-    ydl_opts = {}
-    with youtube_dl.YoutubeDL(ydl_opts) as ydl:
-        ydl.download(['http://www.youtube.com/watch?v=BaW_jenozKc'])
+ydl_opts = {}
+with youtube_dl.YoutubeDL(ydl_opts) as ydl:
+    ydl.download(['http://www.youtube.com/watch?v=BaW_jenozKc'])
+```
 
 Most likely, you'll want to use various options. For a list of what can be done, have a look at [youtube_dl/YoutubeDL.py](https://github.com/rg3/youtube-dl/blob/master/youtube_dl/YoutubeDL.py#L69). For a start, if you want to intercept youtube-dl's output, set a `logger` object.
 
+Here's a more complete example of a program that outputs only errors (and a short message after the download is finished), and downloads/converts the video to an mp3 file:
+
+```python
+import youtube_dl

+    def debug(self, msg):
+        pass
+
+    def warning(self, msg):
+        pass
+
+    def error(self, msg):
+        print(msg)

+
+def my_hook(d):
+    if d['status'] == 'finished':
+        print('Done downloading, now converting ...')
