+    Once dnscrypt-proxy is running, you will have to update your local
+    DNS server to point to 127.0.0.1 in order for it to actually work.
+    This is generally done under System Preferences > Network > Advanced.
+    Once there, you will see a "DNS" tab where you can enter a list of DNS
+    servers. You will want to make sure that 127.0.0.1 is listed there first.
+
+    Note: By default, dnscrypt-proxy runs on 127.0.0.1:53 under the "nobody" user.
+    If you would like to change these settings, you will have to edit the plist file.
+
+    To check that dnscrypt-proxy is running properly, open Terminal and enter this at
+    the command prompt:
+
+        nslookup -type=txt debug.opendns.com
+
+    You should see something like this in the output:
+
+        debug.opendns.com text = "dnscrypt enabled (...)"
