…e.(Grid 3 gridset file renamed to identify it as Grid3).

I'm not sure how you want to arrange the links from the guides to the demo files in resources.

Amazing. Thanks Joe. Yeah I'm not sure where we should pop those files. A few different ideas:

• In the repo. I'd rather not - they can be massive and are zipped
• On the app's own file sharing sites. e.g. Pagesetcentral or Grids online. But can be a right pain in updating them on there - at least instally when a ton of changes happening
• I could use a Sharepoint folder from work - I'd give known folk access.

Maybe its the last one and in the long run we go with pagesetcentral etc

If you prefer I'll give you access to our gitbook site if I can Joe. Might make this a marginally easier process!

im an idiot - I failed to see you've put it in the repo. Joe - im going to merge this and pick up the tweaks from gitbook - you can carry on doing changes directly in the markdown - just do another PR when you want - or do via gitbook. Im easy
