@Jason3S Sorry, I just saw your message. It invalid because -t don't expected any value but in README, it pass $PWD:/workdir as value that should be for -v (--volume option). If you copy the command and run on terminal it will throw docker: invalid reference format: repository name must be lowercase..

$ docker run -v -i -t $PWD:/workdir ghcr.io/streetsidesoftware/cspell:latest lint

docker: invalid reference format: repository name must be lowercase.
See 'docker run --help'.

However, with my fixed:

@kamontat,

Thank you. Strangely it had worked, but clearly should not have.
