Default configuration for glusterd2 when run using systemctl

    systemctl enable glusterd2
    systemctl start glusterd2
    systemctl status glusterd2

Limited config file extension to `TOML` to avoid confusions with
multiple config extensions.

 **Create a config file:** This is optional but if your VM/machine has multiple network interfaces, it is recommended to create a config file. The config file location can be passed to Glusterd2 using the `--config` option.
-Glusterd2 will also pick up conf files named `glusterd.{yaml|json|toml}` if available in `/etc/glusterd2/` or the current directory.
-
-```yaml
-$ cat conf.yaml
-workdir: "/var/lib/gd2"
-peeraddress: "192.168.56.101:24008"
-clientaddress: "192.168.56.101:24007"
-etcdcurls: "http://192.168.56.101:2379"
-etcdpurls: "http://192.168.56.101:2380"
+Glusterd2 will also pick up conf file named `glusterd2.toml` if available in `/etc/glusterd2/` or the current directory.
+
+```toml
+$ cat conf.toml
+workdir = "/var/lib/gd2"
+peeraddress = "192.168.56.101:24008"
+clientaddress = "192.168.56.101:24007"
+etcdcurls = "http://192.168.56.101:2379"
+etcdpurls = "http://192.168.56.101:2380"
 ```
 
 Replace the IP address accordingly on each node.
 
 **Start glusterd2 process:** Glusterd2 is not a daemon and currently can run only in the foreground.
 
 ```sh
-# ./glusterd2 --config conf.yaml
+# ./glusterd2 --config conf.toml
 ```
 
 You will see an output similar to the following:
