where is my .htaccess file?

Hello – I am setting up a local development environment of WP multisite. The WPMU article by Harley Alexander has been excellent so far:


One of the last steps in setup is to make adjustments to the .ht access file. There is no .htaccess file in my wordpress folder so I am not sure what to do. I don’t want to break anything. Can anyone help?

I’m using MAMP pro on mac os 10.7.5
