Fantastic! Indispensable! I don't want to go into the details now common to various platforms, but I do want to dwell on:
1. Importing websites
Import in a flash and convert db and domain, just follow the guidelines given and in no time you have the ability to import a website locally into wordpress.
2. Work directly with the real domain
Redirect the real domain to the local installation in one click and generate the SSL certificate. N.B.: Remember to change the record in /etc/host (if you use Windows) to access the online server again
