I have downloaded the ncp image for the Raspberry Pi, and would like to follow installation and configuration steps with it, however when I try to access the documentation server at https://docs.nextcloudpi.com/ I get Loading… but it never loads (and in the browser inspector it shows that there has been a 502 error, which is likely a system configuration error or similar).
Is there an alternate documentation repository that I can view for installation and configuration guidance, or, failing that, is this the proper place to alert the maintainers of the ncp documentation server of this error?
