+You will need to install the libleveldb library. Install [Python 3.5](https://www.python.org/downloads/release/python-354/) to make sure you don't run into any issues with your version of Python being different than the current maintainer's version. Note that Python 3.6 is not currently supported due to incompatibilities with the byteplay module. 
 
 We have published a Youtube [video](https://youtu.be/oy6Z_zd42-4) to help get you started with this library. There are other videos under the CityOfZion Youtube channel.
