+There are two methods to connect to the CB3 iRODS instance: using your web browser, or via CyberDuck.
+
+### Connect using your web browser
+
+Simply go to [https://cb3-irodsmain.unl.edu](https://cb3-irodsmain.unl.edu) and login using your my.UNL credentials.
+_Please note that the web interface is not suitable for uploading/downloading data in excess of 50MB._  Larger 
+data transfers should use CyberDuck instead.
+
+
+### How to connect using CyberDuck
+
+##### Follow this guide to setup Cyberduck for the first time when connecting to the CB3 iRODS datastore.
+
+1.  Download and install the Cyberduck from [the Cyberduck website](https://cyberduck.io/), or using the following direct links.  
+    Cyberduck can also be installed from the Windows or Mac app store.
+    -  [Windows installer](https://update.cyberduck.io/windows/Cyberduck-Installer-7.0.2.30998.exe)
+    -  [Mac installer](https://update.cyberduck.io/Cyberduck-7.0.2.30998.zip)
+
+2.  <a class="external-link" href="https://cb3-irodsmain.unl.edu/metalnx/images/CB3.cyberduckprofile" ref="nofollow">Download the linked Cyberduck profile (right-click, save-as)</a> to a convenient location.  Some browsers may append `.xml` to the filename. You may need to manually rename it to remove `.xml`.
+
+3.  Double-click on the downloaded file.  It will open Cyberduck and add a new profile with the required information already filled in.
