+Data Science from Scratch
 =========================
 
-code for Data Science From Scratch book
+Here's all the code and examples from my book __Data Science from Scratch__.
+
+Each can be used as a library, for example
+
+```python
+from linear_algebra import distance, vector_mean
+v = [1, 2, 3]
+w = [4, 5, 6]
+print distance(v, w)
+print vector_mean([v, w])
+```
+  
+Or can be run from the command line to get a demo of what it does (and to execute the examples from the book):
+
+```bat
+python recommender_systems.py
+```
