+
+## Requirements
+
+* OpenCV 3
+
+And the following python requirements:
+
+* Theano
+* Lasagne (Dev)
+* numpy
+* scipy
+* flufl.lock
+* parse
+* h5py
+
+which can be installed with
+
+```bash
+pip install -r requirements.txt
+```
+
+## Usage
+
+Build the shared library by
+
+```bash
+cd c-code/build
+cmake ..
+make
+```
+
+To run the test program simply
+
+```bash
+./run.sh
+```
+
+## Note
+
+This model was trained with SfM data, which does not have strong rotation changes. Newer models work better in this case, which will be released soon. In the meantime, you can also use the models in the [learn-orientation](http://github.com/cvlab-epfl/learn-orientation), [benchmark-orientation](http://github.com/cvlab-epfl/benchmark-orientation).
 
-We will make the code available 23rd of October the latest, so please click on the watch button on the top to get notified of the release!
