+##### NOTE:-If you do not have Python installed, it will give an error. To avoid this, run this command *"sudo apt-get install python"* or *"sudo apt-get install python3"* as per your requirement. ALso, after this , even cmake can give some error. You can avoid it by running this command "sudo snap install cmake". Hope this will run for all perfectly :) 
 
 So before you build HermitCore you have to source the `local-cmake.sh` script
 everytime you open a new terminal.
