Making sure Gulp and Gulp-Post CSS are installed

Hi all,

I ran into a couple of issues with following along with this video. I was able to install PostCSS however since Gulp wasn't installed in my project it wasn't running. I assume that when Guil prepared the files for the video he has already installed Gulp on his system.

So I took the plunge and attempted to install gulp the same way as I did PostCSS.

npm install --save-dev gulp

It didn't work on my system, again I assume this works on a Mac. However I'm on a Windows machine, specifiocally a Windows 10 laptop at the moment.

In order to get Gulp to work, I installed it globally.

npm install gulp -g

And it worked! I was able to run Gulp tasks just as in the video.

Furthermore, after running the compiler in the console I found that the task kept finishing instead of waiting for more changes i made to the source CSS file. Well that was because I wasn't running the default task.

I needed to run 

gulp

instead of

gulp css

I hope this is helpful to others maybe struggling to get started with PostCSS :)
