Set your hostname, port, HMAC key, https (must be correct for cookies), and
Redis info in `nitter.conf`. To run Redis, either run
`redis-server --daemonize yes`, or `systemctl enable --now redis` (or
redis-server depending on the distro). Run Nitter by executing `./nitter` or
Redis info in `nitter.conf` or Environment Variables in format of
`NITTER_SECTION_KEY=xxxx` in upper case (for example: NITTER_SERVER_HOSTNAME=nitter.net).
To run Redis, either run `redis-server --daemonize yes`, or `systemctl enable --now redis`
