 ## Setup
 
-This tutorial is designed to run on `lxplus` using a Python environment from CMSSW. In addition we install some extra Python packages, and we use Xilinx's Vivado HLS software from a container on /cvmfs. This tutorial is designed to get you working on the notebooks with minimal setup. For real ML@L1T development work we recommend using a high-memory, high single-core-performance PC with the latest Xilinx tools.
