How to make an alias on mac cli.

I worked with Dillon and Ben yesterday and in the process I saw Dillon type da return and saw the direnv allow process. I thought that is cool, I need to do that. So today I did a quick look and found at https://macosx-faq.com/how-to-make-alias-with-terminal/ how you can create your own alias.

alias da='direnv allow'
