 #### How to connect
 
 ##### Kerberos Setup
+
 There are two Kerberos _Key Distribution Centers_ (KDCs) setup: `kdc-admin` and `kdc-admin2`. These two cover the `EXAMPLE.COM` and `EXAMPLE2.COM` realm respectively. All users listed below are registered in the `EXAMPLE.COM` realm. The service principals for `mongodb-kerberos-1` and `mongodb-kerberos-2` are also registered in the `EXAMPLE.COM` realm. The service principal for `mongodb-kerberos-3` is registered in the `EXAMPLE2.COM` realm.
 
 The two Kerberos installations have cross-realm authentication enabled so that `kdc-admin2` (realm `EXAMPLE2.COM`) **trusts** `kdc-admin` (realm `EXAMPLE.COM`). For details on how this cross-realm trust is configured refer to [Setting up Cross-Realm Kerberos Trusts](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/system-level_authentication_guide/using_trusts).
