 # Description
-The Cointraffic client module makes it easy to implement Cointraffic directly into your website. To get started, simply replace the ``placementId`` with your assigned tracker key. This is dependent on the size required by your account dashboard. For additional information on this module, please contact us at ``[email protected]``.
