Redirect url

This is the problem:

A. I have brochures printed with the url

B. The url should be

C. When the incorrect url is entered a 404 error results.

D. How do I redirect from the incorrect address to the correct address (the one with .html on the end)?

Reading around I see that a 301 Redirect seems to be the best bet but before I dive into .htaccess files (about which I know very little) I just want to be sure there is not an easier way.

If I have to do some new coding is there a step by step process anywhere?

There’s not an easier way.

This particular task is very easy. See RedirectMatch Directive

RedirectMatch 301 ^/yourfreereources$

Thank you - at least I know now.
