+If you'd like to develop qsimcirq, a separate set of dependencies are includes
+in the
+[`dev-requirements.txt`](https://github.com/quantumlib/qsim/blob/master/dev-requirements.txt)

 ## Linux installation
 
 We provide `qsimcirq` Python wheels on 64-bit `x86` architectures with `Python 3.{6,7,8,9}`.
