 ''Note : this is a good practice to use a DNS alias as the top-level BDII name. This allows to change the actual top-level BDII without editing configuration. This has the advantage that the change is taken into account by running jobs (if there is no DNS caching on the WNs).''
+=== Configuring BDII aliases ===
+When several BDIIs are used to provide the same BDII service (either top or site) in order provide service load balancing and/or failover, they are generally all associated with a DNS alias (`CNAME`). In this configuratin, the endpoint plublished for the BDII should be the alias instead of the BDII host name (default). This is done by one of the following variables, depending whether the BDII is a site BDII or a top BDII:
+ * `BDII_ALIAS_TOP`: DNS name to use in the top BDII endpoint.
+ * `BDII_ALIAS_SITE`: DNS name to use in the site BDII endpoint.
