INSTALL.md

thor install app_create.thor Make sure that the templates__generic_gemfile.erb is renamed and moved to ~/.thor/templates/generic_gemfile.erb

Then you can run thor list to verify that the script was installed successfully. If the command appears in the output, you should be good to run thor app:create APP_NAME.
