For example,
1. Its not totally clear that the url that you are supposed to use is the url that is generated when you create a new app and land inside of Forge.
2. Its also not totally clear that in retrieving data you're supposed to follow the structure of you JSON schema. A simple note along the lines of "If you would like the retrieve the third index in your array, its as simple as creating a new Firebase instance and passing in 'mydata.firebaseio.com/3' as the url.
3. Like I mentioned in my first comment, it would be good if you had a 'Retrieve Data' bullet point on your getting started page. For users who simply want to import JSON into Forge to display in their app via retrieval, a two line note and example along the lines of
Retrieve Data
user = new Firebase('mydata.firebaseio.com/users/3')
user.once (userData) ->
console.log userData.val() # Should return Kim Gordon
would help.There are little things (and I emphasize little here) scattered throughout which would lead less experienced devs into a bit of confusion when first getting started.
If I'm being overly cautious here please disregard, but it did hang me up when I first started playing around with the system.
Either way, totally love the hosting and super psyched to dive deeper into the platform!
