mod_rewrite help – CodeIgniter WP

I have a CodeIgniter application running and installed WP under cms/ folder. I am able to access WP pages provided /cms/ is in the URL. However, I want to eliminate the /cms/ part of the URL. So:

Instead of: https://www.domain.com/cms/my-article-in-wp/
I want: https://www.domain.com/my-article-in-wp/

I assume I need to do something with the .htaccess file in /cms. I’m no .htaccess expert, though.

Help please.
