That was the authoritative guide but needs updating. Probably greatly simplified. 

The primary recommendation for 4.11 is going to be RSB with some hints that there is support for some supporting programs and add on libraries for the target. This will be short and a series of pointers. 

Then some info on cloning RTEMS, and pointers.

I don't see mentioning instructions for hand building.  The arguments to the GCC configure are horribly long now. Many are Newlib specific for iconv settings. 

And I don't think we support binaries so that goes.

If there are windows specific advice, we can point them to help.

I think a very reduced getting started should exist. It has always been in the list of docs so something minimal with pointers needs to still be there.
