CruiseControl.Net plugin for nunit3

Question

It seems that the syntax for running nunit has changed between nunit 2 and 3. I would like to move my existing CruiseControl.Net configuration to use NUnit 3, but I cannot work out how to modify my existing target (see below) to use nunit3. Is there documentation anywhere? Thanks for any help.

<nunit>
 <environment>
     <variable name="TEST_FILES_DIRECTORY" value="C:\TestPlans\TestFiles" />
 </environment>
 <path>C:\nunit3\Compiled\nunit3-console.exe</path>
 <assemblies>
     <assembly>C:\source\TestRunner\bin\Debug\Tests.dll</assembly>
 </assemblies>
 <includedCategories>
     <includedCategory>Data</includedCategory>
 </includedCategories>
 <timeout>72000</timeout>
</nunit>
