+### Connection URL
+
+The connection URL for Phoenix set with `phoenix.connection-url` supports multiple formats:
+
+* `jdbc:phoenix[:zk_quorum][:zk_port][:zk_hbase_path][:principal][:keytab][;options]`:
+  Connection uses the HBase Zookeeper Registry. `zk_quorum` is a comma-separated
+  list of ZooKeeper servers. `zk_port` is the ZooKeeper port.
+  `zk_hbase_path` is the HBase root znode path, that is configurable using
+  `hbase-site.xml`.  By default the location is `/hbase`. Principal, Keytab and
+  Options are optional.
+* `jdbc:phoenix+zk[:host1\:port1][,:host2\:port2]...[,:hostN\:portN][:zk_hbase_path][:principal][:keytab][;options]`:
+  Uses the same connection as the preceding example with `host:port` pairs as a comma-separated list.
+* `jdbc:phoenix+rpc[:host1\:port1][,:host2\:port2]...[,:hostN\:portN][::principal][:keytab][;options]`:
+  Connection uses the HBase RPC Registry. Recommended for HBase 3+
+  versions. `host:port` pairs are comma-separated.
+  Host names refer to HMaster server names, port refers to HMaster ports.
+  Principal, Keytab and Options are optional.
+* `jdbc:phoenix+master[:host1\:port1][,:host2\:port2]...[,:hostN\:portN][::principal][:keytab][;options]`:
+  Connection uses the HBase Master Registry. `host:port` pairs are comma-separated.
+  Host names refers to HMaster server names, port refers to HMaster ports.
+  Principal, Keytab and Options are optional.
