The Example instructions only work for one of the examples

[martinsk]

Thank you for making an awesome project, I found that the instructions for testing out the examples seems to be little out of date.

The example instructions:

opam install incr_dom
dune build example/incr_decr/bin/{main.bc.js,index.html}
Open _build/default/example/incr_decr/index.html in a web browser

are misleading, the generated code is not in _build/default/example/incr_decr but in _build/default/example/incr_decr/bin

The steps do not work for building any of the other examples provided in the repo :(
