    a) Create and edit /etc/turnserver.conf or
    /usr/local/etc/turnserver.conf .
    Use /usr/local/etc/turnserver.conf.default as an example.

    b) For user accounts settings: set up SQLite or PostgreSQL or
    MySQL or MongoDB or Redis database for user accounts.
    Use /usr/local/share/turnserver/schema.sql as SQL database schema,
    or use /usr/local/share/turnserver/schema.userdb.redis as Redis
    database schema description and/or
    /usr/local/share/turnserver/schema.stats.redis
    as Redis status & statistics database schema description.

    If you are using SQLite, the default database location is in
    /var/db/turndb or in /usr/local/var/db/turndb or in /var/lib/turn/turndb.

    c) add whatever is necessary to enable start-up daemon for the
    /usr/local/bin/turnserver.
