 * there are undocumented incompatibilities between kernel versions, nvidia driver versions and nvenc SDK versions. If possible, install the driver version bundled with the nvenc SDK. For more details see ticket:370#comment:14
+If you ignore this warning, you may get undecipherable errors at runtime (incompatible structure version errors, etc).
 
 
 == Using NVENC ==
-TODO!
 
+Because of the unusual location of the CUDA and NVENC libraries and support tools, it is your responsibility to ensure that the required shared objects and the CUDA compiler can be located at runtime.
+You can specify the paths each time on the command line:
+{{{
+PATH=$PATH:/opt/cuda-5.5/bin/ \
+LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/opt/cuda-5.5/lib64:/usr/lib64/nvidia \
+ xpra ...
+}}}
+Or make those settings more permanent in your user or system profile.
+
+
+Beware that the new paths added to {{{PATH}}} and {{{LD_LIBRARY_PATH}}} should be added '''at the end''' of the current values (as per the example above) to prevent a conflict with system critical libraries. (ie: {{{libOpenCL}}} is known to cause crashes)
+
+
+== License Key ==
+If you have access to a license key, you can specify it like so:
+{{{
+XPRA_NVENC_CLIENT_KEY="0A1B2C3D-4E5F-6071-8293-A4B5C6D7E8F9" xpra ...
