Feature request: Add description on how to use it for a script

I want to time each commands in a bash script. It has no functions.
Is it possible to use the bash-command-timer for this task?

I tried it with no luck. I tried it with adding ```. /path/to/bash-command-timer.sh``` and with ```bash /path/to/bash-command-timer.sh ./myScript.sh```, this didn't work.
