A note, though, goDaddy normally requires RewriteBase /

Quick 'n dirty

RewriteEngine On
RewriteBase /
RewriteRule ^/?about/?$ about.php [L,NC,QSA] # domain.com/about is sent to the server as domain.com/about.php
RewriteRule ^/products/([0-9]+)$ /products.php?id=$1 [L,NC,QSA]  # domain.com/products/23 is sent to the server as domain.com/products.php?id=23
