Any way to repair Jitsi Installation?

I messed up my Jitsi + Jibri. I was trying to clone and then make changes locally to then sync. I got up to configuring Nginx, but then started getting some errors. Went searching for some possible fixes and tried a ‘solution’ that someone posted online:

sudo apt-get remove --purge nginx nginx-full nginx-common

Unfortunately, this completely screwed up my installation. It removed Nginx, but also removed my Jitsi installation e.t.c. I’d saved my Nginx .conf file before trying anything, so I still have the configuration. Is there any way of getting my system back without having to start (Jitsi and Jibri installation) all over? Per chance anyone would be able to advise quickly? I"m under a bit of a time crunch and I’d hate to have to start all over. :confused:
