#Create New Workflow Default Settings
##File to edit: your gems version or path might be different to double check on that use "gem which tmuxinator" this provide you the full path example
/Library/Ruby/Gems/2.0.0/gems/tmuxinator-0.6.11/lib/tmuxinator.rb
The file is going to be a "READ ONLY" file so you might not be able
to save in on vim depending on the settings you have. vim /Library/Ruby/Gems/2.0.0/gems/tmuxinator-0.6.11/lib/tmuxinator/assets/sample.yml
If you want to open it with sublime instead you can just use: subl /Library/Ruby/Gems/2.0.0/gems/tmuxinator-0.6.11/lib/tmuxinator/assets/sample.yml
It will ask you for your password in order to save the file after that you all set ready to go with your own default file.
