# default nginx site config for Pleroma
#
# Simple installation instructions:
# 1. Install your TLS certificate, possibly using Let's Encrypt.
# 2. Replace 'example.tld' with your instance's domain wherever it appears.
# 3. Copy this file to /etc/nginx/sites-available/ and then add a symlink to it
#    in /etc/nginx/sites-enabled/ and run 'nginx -s reload' or restart nginx.
