QupKake instead of qupkake

Hi,

Thanks for make this great tool available. Tiny thing to fix in the installation instructions: cloning the github repository generates e folder 'QupKake', not qupkake, hence issueing 'cd qupkake' will not work. This is easy to see and fix for experienced users but maybe not so for novices.

also if possible, "conda env create -f environment.yaml " ?
