+# Examples, examples, examples
+If there's one thing I love is examples, they are often minimal and not very 
+explicative, moreover multiple examples on the same subject are never the same.
+That said, if you need to reverse-engineer something examples are (most of the
+times)your only resource.
+
+Here's some categorized examples about ALSA:
+
+## The PCM interface
+
+* some [dwm bar](https://github.com/kamiyaa/dwmstatus/tree/master/src) that
+has some good simple code
+
+## Configuration files
+
+* [volh](https://gist.github.com/volh/4587051): play through internal and
+external sound cards, whatever that means
