In ftxui_template, repository name is used for changing project name in CMakeLists.txt, configured_files/config.hpp.in, src/main.cpp files. template_janitor.yml is literally replaces namespace name to repo name. If repo name contains hypens or any other characters which are not allowed as part of identifiers. it breaks the code.
Please add a note regarding this issue, this will save time for people, Thank you.
