very.quick.and.dirty

have a linux system, 

be able to download the actual parity version

at

https://github.com/paritytech/parity/releases

nowhere else!

Get the deb file.
Install it with sudo dpkg -i parity-1.8.n (tab-to-end)


start manual time synchronisation with ntpq -p

wait for the results

start parity with 

parity -v
to now for yourself which version is now installed

and then start parity without any parameters-

it should start-
with a standard config, you now start your own ethereum node,
also able to use the ethereum classic chain with only one configuration flag-

easy going
