Art Gallery Website Mobile First SCSS Gulp Leaflet JS

I used Gulp for the first time with this project, and it took a lot of debugging and trial and error to get the project to first compile to Netlify, and then for the project to show up when launched. Through research i discovered that my index.html was not at the root of the project, and so i was able to tweak so the project worked. I feel that i kind of hacked it to work, and that the processes weren't 100% correct. I used a build task in my gulp file, but didn't really utilise a build folder as such, apart from to hold my project images.

It would be good to know any alternatives for approaching gulp builds, specifically with Neflify.
