Suggestion to clarify relative path
Suggestion to clarify relative path

Thanks for this tool - I used it setting up for SWC instructor checkout with `./swc-shell-split-window.sh` and plan to use it in future.

My understanding is that the command under **Use** section won't work as written for many people if they don't have the current directory added to their $PATH, so it'd be helpful to either add `./` to the start of the example and/or add a note that this may be necessary
