+A. Setup
+
+An init script and configuration file have been provided to run dnscrypt-proxy
+as a daemon. To configure dnscrypt-proxy, edit /etc/default/dnscrypt-proxy with
+the desired settings. By default dnscrypt-proxy will use an OpenDNS server and
+will run on localhost (127.0.0.1), port 53.
+
+The configuration file is setup to use a dnscrypt user by default, and to
+chroot into that user's home directory to maximize security. In order to use
+the default configuration you should create a dnscrypt user and group with the
+following commands:
+
+    groupadd -g 293 dnscrypt
+    useradd -u 293 -g 293 -c "DNSCrypt" -d /run/dnscrypt -s /bin/false dnscrypt
+
+If you decide to use another user you should edit the CHROOTDIR and USER
+options in /etc/default/dnscrypt-proxy (there are example settings provided for
+the user 'nobody').
+
+In order to send all DNS requests through dnscrypt-proxy, you will need to
+update /etc/resolv.conf to point to localhost. If using dhcpcd, the easiest way
+to set dnscrypt-proxy as the primary (but not exclusive) dns resolver is to
+create file /etc/resolv.conf.head with the following line:
+
+    nameserver 127.0.0.1
+
+You may also have to add the following line to enable EDNS:
+
+    options edns0
+
+To start dnscrypt-proxy automatically at system start, add the following to
+/etc/rc.d/rc.local:
+
+    if [ -x /etc/rc.d/rc.dnscrypt-proxy ]; then
+        /etc/rc.d/rc.dnscrypt-proxy start
+    fi
+
+To properly stop dnscrypt-proxy on system shutdown, add the following to
+/etc/rc.d/rc.local_shutdown:
+
+    if [ -x /etc/rc.d/rc.dnscrypt-proxy ]; then
+        /etc/rc.d/rc.dnscrypt-proxy stop
+    fi
+
+B. DNS Cache
+
+dnscrypt-proxy is just a DNS resolver and does not cache DNS queries. In order
+to minimize the number of external DNS lookups, you can also run a local
+caching DNS server. A sample configuration for dnsmasq (included with
+Slackware) is provided at /usr/doc/dnscrypt-proxy-@VERSION@/dnsmasq.conf. A
+sample configuration for bind/named that also does local DNSSEC validation (if
+supported by the upstream DNS server) is also provided at
+/usr/doc/dnscrypt-proxy-@VERSION@/named.conf. Both configurations run on port
+53, forwarding lookups to dnscrypt-proxy running on port 55. In order to use
+these configurations you will need to change the port dnscrypt-proxy runs on in
+/etc/default/dnscrypt-proxy.
