# Sample Apache config for Akkoma
#
# Simple installation instructions:
# 1. Install your TLS certificate. We recommend using Let's Encrypt via Certbot
# 2. Replace 'example.tld' with your instance's domain.
# 3. This assumes a Debian-style Apache config. Copy this file to
#    /etc/apache2/sites-available/ and then activate the site by running
#    'a2ensite akkoma-apache.conf', then restart Apache.
#
# Optional: enable disk-based caching for the media proxy
# For details, see https://docs.akkoma.dev/stable/configuration/howto_mediaproxy/
#
# 1. Create a directory as shown below for the CacheRoot and make sure
#    the Apache user can write to it.
# 2. Configure Apache's htcacheclean to clean the directory periodically.
#    Your OS may provide a service you can enable to do this automatically.
