About your Site:
The WordPress theme your site is built on is called Divi. The more you work with it, the more comfortable you will be when editing text, adding images, etc… You can access specific training videos and documentation on different modules and options by going to Appearance>Divi Training in the left hand toolbar.
If you find yourself wanting to better understand WordPress or are wanting some more in-depth tutorials, I recommend this site: www.wp101.com. You can also google your questions on YouTube and often finds hundreds or walk-thru videos. But feel free to email me at firstname.lastname@example.org with any issues or questions you may need.
