Setup

Ensure everything is up to date by running sudo npm update after cding into the directory this file lives in
Configure your gulpfile.js as needed (and see what tasks are available)
Run gulp to dev: (pre-)compiling, file watching, browser-relaoding, etc.
Run sudo ulimit -n 8192 if you get a 'memory limit exceeded' error
Run gulp -s (or gulp --silent) to prevent launching a new live-reloading browser window
Run gulp -g (or gulp --ghost) to sync all browser page changes, scrolling, and clicks between clients

Structure

src/assets/scripts/ should contain your source code, whereas build/assets/js/ should contain only dynamically generated javascript
src/assets/styles/, likewise, should contain your source code, whereas build/assets/css/ should contain only dynamically generated css
src/assets/images/ is for all site-specific static images; any user-uploaded content should be kept elsewhere
src/assets/icons/ is for all SVG icons; they will be minified/optimized into build/assets/icon/
src/views/ is for partials to be rendered as full view templates (e.g. public vs. authenticated, header1 vs. header2)
src/views/page/ is for partials that will be included in other views (e.g. subviews)
src/templates/ is for general-purpose partials (i.e. angular directive templates, re-used UI elements, or repeated content sections)
