Just started learning fuse about 6 hours ago… love it, love it, looooove it.
Now, on downloading the background.jpg for the quickstart tutorial, the jpg didn’t show up…
So naturaly, I decided to look at the monitor and this is what I got:
So in the Navigating and Routing tutorial, it would be best to change the Default Template="home" to DefaultPath="home"
An in the Tweak look and feel tutorial, under change background image, by default (when you right click > open in new tab ) it opens the webp edition of the background image.
Which i think is caused by the structure of the html:
Simpler to provide some sort of warning that if the img doesn’t load just convert to jpg… or maybe reposition the source and img tags up there ( dunno if that will fix it )
Otherwise, can’t wait to finish the tuts and tear apart the docs… 
The downside is that this part of the doc had a hard-coded link to an older version of our website which used JPEG images for every client.
