Give a clearly dissuading tone on end users trying 512KB version

@ -20,9 +20,12 @@ characteristic of a board is how much flash it has, how the GPIO pins are
connected to the outside world, and whether it includes a built-in USB-serial
convertor to make the UART available to your PC.
The minimum requirement for flash size is 512k. A board with this amount of
flash will not have room for a filesystem, but otherwise is fully functional.
If your board has 1Mbyte or more of flash then it will support a filesystem.
The minimum requirement for flash size is 1Mbyte. There is also a special
build for boards with 512KB, but it is highly limited comparing to the
normal build: there is no support for filesystem, and thus features which
depend on it won't work (WebREPL, upip, etc.). As such, 512KB build will
be more interesting for users who build from source and fine-tune parameters
for their particular application.
Names of pins will be given in this tutorial using the chip names (eg GPIO0)
and it should be straightforward to find which pin this corresponds to on your
