This tutorial was made by a community member of NULS today. It's a tutorial for the web wallet but you can also use the PC, Mac or Linux wallet as it's very similar.

If you use the web wallet make sure to use the incognito mode in case your browser has malicious extensions. Remember that extensions can read any content on the pages you visit.

Make also sure to backup your private key, keystore file and password in a very secure place and keep copies at different locations (in case of a fire for example). I recommend 2 different bank vaults.
