I've made it to part 19 of the WordPress Plugin Development tutorial on youtube. I know the basics of npm and gulp and I've installed those on my dev machine. I restructured my directories to fit the tutorial and I've downloaded the package.json and ran the npm install command. I've also downloaded the gulpfile.js and edited it to my directories ( with one exception, which is where my error comes in).
The gulp.task for browser-sync appears to point to a key and a crt. obviously without being on Alecadd's system I wouldn't have that directory path nor the key or crt. I'm not sure how to configure this componenet or what it actually does. Any help is appreciated
