Scribe Theme Content Customization

I have installed the supplied Scribe theme but I find that updating the content is a bit painful because its slow updating through the customize option. Is there another way to edit the website? Code would even be quicker.

Also, do you provide precise instructions on how to edit the content out on the Scribe theme? I really don't know what I'm doing besides pointing and clicking. There are some content areas on certain pages I'm trying to duplicate but its not very user friendly.
