                   [-c CONDA_NAME] [-gh]

optional arguments:
  -h, --help            show this help message and exit
  -n PROJECT_NAME, --project-name PROJECT_NAME
                        Name of the project
  -p PYTHON_VERSION, --python-version PYTHON_VERSION
                        Python version for the project. Default: 3.5
  -r REPO_NAME, --repo-name REPO_NAME
                        If you already have a github repo for the project.
                        Enter the repo name.
  -c CONDA_NAME, --conda-name CONDA_NAME
                        If you already have a conda environment for the
