File Structure

Hello,

Now that I have my sub theme successfully generated via Drush, I've started customizing it. I'm familiar with Bourbon/Neat, as that's what led me to this base theme, but I'm not clear on what the recommended way is for organizing and modifying the files generated for the sub-theme. I'm hoping to understand the most efficient way to use this NEATO while I'm still in early stages of development on my current project before I get to far along and realize I did something very unsustainable.

For example, I don't want Helvetica as my $base-font-family. Instead I would like to use Source Sans Pro. In my sub theme SCSS folder, I modified the _variables.scss to make that change. I also changed the $base-font-size and created some additional variables for Font Sizes.

Is it best practice to modify these generated SCSS files, or should I only be adding my customization to the SUBTHEME-NAME.SCSS file?

These questions come for me again with the _layout.scss and _grid-settings.scss file. Should I modify what is set in these files, or should I override them in SUBTHEME-NAME.SCSS file?

Greatly appreciate any insight with this.

Apart from my confusion in this area, I think this is an awesome base theme.

Thank you!
