+* <a id="advertise"></a>`-advertise` - The advertise address is used to change the address that we
   advertise to other nodes in the cluster. By default, the `-bind` address is
   advertised. However, in some cases, there may be a routable address that cannot
   be bound. This flag enables gossiping a different address to support this.
   If this address is not routable, the node will be in a constant flapping state
   as other nodes will treat the non-routability as a failure.

+* <a id="bootstrap_anchor"></a>`-bootstrap` - This flag is used to control if a server is in "bootstrap" mode. It is important that
   no more than one server *per* data center be running in this mode. Technically, a server in bootstrap mode
   is allowed to self-elect as the Raft leader. It is important that only a single node is in this mode;
   otherwise, consistency cannot be guaranteed as multiple nodes are able to self-elect.
   It is not recommended to use this flag after a cluster has been bootstrapped.
 
-* `-bootstrap-expect` - This flag provides the number of expected servers in the data center.
+* <a id="bootstrap_expect"></a>`-bootstrap-expect` - This flag provides the number of expected servers in the data center.
   Either this value should not be provided or the value must agree with other servers in
   the cluster. When provided, Consul waits until the specified number of servers are
   available and then bootstraps the cluster. This allows an initial leader to be elected
   automatically. This cannot be used in conjunction with the `-bootstrap` flag.
 
-* `-bind` - The address that should be bound to for internal cluster communications.
+* <a id="bind"></a>`-bind` - The address that should be bound to for internal cluster communications.
   This is an IP address that should be reachable by all other nodes in the cluster.
   By default, this is "0.0.0.0", meaning Consul will use the first available private
   IP address. Consul uses both TCP and UDP and the same port for both. If you
   have any firewalls, be sure to allow both protocols.
 
-* `-client` - The address to which Consul will bind client interfaces,
+* <a id="client"></a>`-client` - The address to which Consul will bind client interfaces,
   including the HTTP, DNS, and RPC servers. By default, this is "127.0.0.1",
   allowing only loopback connections. The RPC address is used by other Consul
   commands, such as `consul members`, in order to query a running Consul agent.

   This is required for all agents. The directory should be durable across reboots.
   This is especially critical for agents that are running in server mode as they
   must be able to persist cluster state. Additionally, the directory must support
   the use of filesystem locking, meaning some types of mounted folders (e.g. VirtualBox
   shared folders) may not be suitable.

   it defaults to "dc1". Consul has first-class support for multiple data centers, but
   it relies on proper configuration. Nodes in the same data center should be on a single
   LAN.
