Gulp and npm instructions incorrect

I required many extra steps to get this working beyond the instructions in the README.md. Likely, your npm and bower and gulpfile need updating for this to work. I had to include the following steps and still SASS was not compiling:
- git clone https://github.com/BioPhoton/ng-drupal-services-tests-with-ng.git drupal-services-tests
- cd drupal-services-tests/
- git checkout master
- npm install
- bower update
- vi src/app/app.config.js
- \* add Drupal instance and API endpoint
- vi gulpfile.js
- \* uncomment bottom gulp commands, including webserver
- \* modify line 215 to gulp.src('./www/')
- npm install wrench
- npm install wiredep
- npm install run-sequence
- npm install gulp-minify-css
- npm install gulp-server-livereload
- npm install gulp-bundle-assets
- npm install
- cp -R src www
- cp -R bower_components www/
- gulp webserver

Start with README.md and gulpfile.js, then reproduce the listed clone, npm, bower, and gulp steps. Compare the documented setup with the reported manual edits and missing packages; done means the documented setup completes and Sass compiles without those extra changes.
