Documentation issues

[simone-hochgreb]

This is a good contribution.

I could get the straightforward examples running, but I am having serious trouble adapting my original .rst pages with this interface, because it is difficult to find documentation on the classes and attributes.

For example, looking at the featurette under the carousel example:

` .. container:: col-md-5

 .. container:: featurette-image img-fluid mx-auto
    :tagname: img
    :attributes: data-src="holder.js/500x500/auto"
		 alt="Generic placeholder image"
    :endless:

`

All I am I trying to do is to change the number of columns the figure/test occupy, and change the figure. But I don't seem to be able to get the image I have (pointing it to the file in a subfolder) to be read.

Is it possible to get a list of the features that each class has and the syntax for its usage? I have spent many hours on this now, and about to give up.

I have all my pages using Ryan Roemer's rest to bootstrap, but it has some limitations, so I was keen to use the present one, but I cannot find sufficient documentation to port them.

I would appreciate any pointers.
