Installation instructions lack explicit hints about proprietary firmware
New users to replicant might start just installing the distribution on their phones by downloading the latest image and flashing it by following the installation instructions. They end up with a system, where hitting the "on" button for wifi would just do nothing, giving no feedback to the user why it does not work and no hints how this can be overcome. Novices might get the impression that there is an awful bug in replicant and the functionality is simply broken.
Also, there is no explicit hint that these things (like wifi, blueooth for the nexus s) will NOT WORK unless the proprietary firmware files are flashed. Unfortunately, after flashing replicant the firmware files are gone, so users would either have to download them somewhere else, extract them from the official factory images (where available) or first flash back to the previous distruction, pull them from there via adb (instructions for this are only anecdotal!) and then flash replicant again and install these firmware files.
I would highly suggest to place an explicit hint in the installation guides, so users wishing to have a "useable" device will now that they need to extract these firmwares beforehand plus maybe some hints on how to do that.
