watch-task.js

gulp.task('watch', function () {
    gulp.watch('./development/styles/*.scss', ['sass'] );
    gulp.watch('./development/scripts/*.js', ['scripts'] );
});

I have two observations
1.) npm says this: " npm WARN deprecated gulp-minify-css@1.2.3: Please use gulp-cssnano instead".
2.) I get this error when I run gulp include: "ReferenceError: include is not defined".
