 # Synapse-Docker-Compose
 Matrix Synapse Docker-Compose
 
+No longer maintained as we switched to a bare metal setup on Ubuntu + ZFS. For a large server, the I/O is too high so we need to optimize performance as much as we can.
+
 1. Update `docker-compose.yml`
 2. Update the hostname in `swag/nginx/proxy-confs/synapse.subdomain.conf`, `swag/nginx/proxy-confs/element.subdomain.conf`, and `swag/nginx/proxy-confs/matrix-to.subdomain.conf` approprieately.
 3. Run `docker-compose run --rm -e SYNAPSE_SERVER_NAME=yourdomain.tld -e SYNAPSE_REPORT_STATS=no synapse generate`
