+#Primary Directory#
+
+By default, $Projectname will use available Directories on the web, which show you channels available around the world.
+
+There are certain scenarios where you might want your own directory-server that you can connect multiple hubs to. This will limit the channels that appear in all of your hubs to only channels on hubs connected to your directory-server.
+
+
+
+##Instuctions on how to set up one hub as the Primary Directory for a series of private hubs.##
+***
+
+
+*   On the hub that will be the Directory Server, open the .htconfig.php file and set:
+
+    `$a->config['system']['directory_mode'] = DIRECTORY_MODE_PRIMARY;`
+
+
+    By default it should already be set as **DIRECTORY_MODE_NORMAL**, so just edit that line to say **DIRECTORY_MODE_PRIMARY**
+
+*   Next, for each hub (including the Directory Server), from a terminal,  cd into the folder where it is installed and run this :
+
+    `util/config system directory_realm YOURREALMNAME`
+
+    (**YOURREALMNAME** can be whatever you want your realm-name to be)
+
+    then:
+
+    `util/config system realm_token THEPASSWORD`
+    
+    (**THEPASSWORD** is whatever password you want for your realm)
+
+    **NOTE:** Use the same realm-name and password for each hub
+
+*   Lastly, for each "client" hub, (from a terminal) run:
+
+    `util/config system directory_server https://theaddressofyourdirectoryserver.com`
+
+***
+Now when you view the directory of each hub, it should only show the channels that exist on the hubs in your realm. I have tested with two hubs so far, and it seems to be working fine.
+Channels created in each hub are reflected in the Primary Directory, and subsequently in the directory of all client hubs
+
+##Issues##
+***
+
+When I created the first hub,it was up and running for an hour or so before I changed it to PRIMARY_MODE, and after changing it, there were a few channels from across the matrix still present in the directory. I deleted them from the xchan table and that seems to have fixed the issue.
