To integrate Zeus with TFS (Team Foundation Server) just download and install the TFS MS-SCCI plugin from the link below:
Team Foundation Server MSSCCI Provider 2010
Team Foundation Server MSSCCI Provider 2013 & 2015
Once installed, Zeus will integrate with TFS just like any other MS-SCCI compatible source control.
Note: For the TFS MS-SCCI plug-in to work it relies on the 'Microsoft Visual Studio 2013 Team Explorer' component. The easiest way to install this component is to just install the Visual Studio 2013 Community IDE.
