+## ranger python bindings
+
+### Overview
+
+These are pretty minimal python bindings for ranger - they work but don't expose much functionality. Essentially only a RandomForestClassifier class with sklearn-like API is exposed.
+
+
+### Installation
+
+```
+git submodule update --init --recursive
+./waf configure
+./waf
+./waf install
+```
+
+### Example usage
+
+```python
+import pyranger
+import numpy as np
+from sklearn import datasets
+
+iris = datasets.load_iris()
+X = iris.data
+y = iris.target
+
+rf = pyranger.RandomForestClassifier()
+rf.fit(X, y)
+y_pred = rf.predict(X)
+
+print(np.where(y_pred != y))
+```
