  -Quick Installation and Example Usage
  --------------------------------------
  -XACC and plugin binaries are available via PyPi as Python Wheels:
  -```bash
  -$ python -m pip install --user xacc[all]
  -```
  -
  -With XACC installed, one can compile and run quantum kernels in python and
  -run on available QPUs and simulators:
  -```python
  -import xacc
  -
  -# Initialize the framework
  -xacc.Initialize()
  -
  -# Select the QPU you want to use and
  -# allocate some qubits
  -qpu = xacc.getAccelerator('rigetti') # or ibm, tnqvm, etc..
  -qubits = qpu.createBuffer('q',2)
  -
  -# Annotate functions that are to be
  -# run on the QPU
  -@xacc.qpu(accelerator=qpu)
  -def entangle(buffer):
  - H(0)
  - CNOT(0, 1)
  - Measure(0, 0)
  - Measure(1, 1)
  -
  -# Execute, gather results
  -entangle(qubits)
  -print(qubits.getMeasurementCounts())
  -
  -# Cleanup
  -xacc.Finalize()
  -```
  Build from Source
  -----------------
  Ensure that you have installed CMake 3.2+, a C++11 compliant compiler (GCC 5+, Clang 3.8+), and OpenSSL development libraries (see [prerequisites](http://xacc.readthedocs.io/en/latest/install.html#pre-requisites)).
