For convenience you can add alias of the command to your shell config:
$ echo "alias tz='docker run --rm -it -v ${HOME}/.tz-cli:/home/tz/.tz-cli ghcr.io/yankeexe/timezones-cli'" >> ~/.bashrc $ source ~/.bashrc

$ tz search Nepal

For local debugging: Use the make run command followed by the command you want to run against the tz binary.

$ make run cmd="get ist"
