+## How to install
 
+1. Clone this repository ```git clone https://notabug.org/necklace/libray```
+
+2. Install dependencies with ```sudo pip install -r requirements.txt```
+
+3. Run ```sudo python setup.py install```
+
+Note: You will need Python 3, so you might want to use `python3` and `pip3`.
+
+`libray` is now installed to your path. In the future I'll add this package to pypi.

+or
+
+> ImportError: cannot import name 'byte_string' from 'Crypto.Util.py3compat' (/usr/lib/python3.7/site-packages/Crypto/Util/py3compat.py)

+```
+sudo pip uninstall crypto
+sudo pip uninstall pycrypto
+sudo pip install pycrypto
