ERROR while downloading Rector

[ToTDJeanR]

I'm following the steps to download Rector, but when I try to do this command :
vendor/bin/rector process src --dry-run
this error message is poping

[ERROR] The following given path does not match any file or directory:
          - src

edit: i'm not friend with the cmd prompt so even if it's a stupid problem, I need help

Look at the error, you don't have directory named "src", change command argument and verify with directory you have, read documentation, slowly https://getrector.com/documentation

I followed those steps again, I still got errors..
`$ php vendor/bin/rector

[ERROR] The file "/var/www/utils/src" does not exist.
`
Where the path is defined ?

Read the documentation https://getrector.com/documentation/define-paths
