Hello,
We don’t have a special video tutorial for the header, so follow the instructions:
1) Enable WPbakery for the static block https://xstore.helpscoutdocs.com/article/47-static-blocks
2) Go to Static Blocks > create static block for the header using 2 columns layout and WPBakery elements.
3) Copy the static block shortcode http://prntscr.com/oy8xur and paste it to header custom HTML area. Save options and check the frontend.
Regards
