+### Iluvatar CoreX
+
+NVTOP supports Iluvatar CoreX GPUs through the ixML library.
+
+The backend dynamically loads `libixml.so` from `/usr/local/corex/lib`,
+`/usr/local/corex/lib64`, or the default dynamic loader search path. The ixML
+runtime exposes an NVML-compatible API surface used by NVTOP to query device,
+power, PCIe, clock, temperature, memory, and process information.
+
 ### VideoCore
 
 NVTOP supports VideoCore (testing on raspberrypi 4B).
@@ -173,6 +184,8 @@ Several libraries are required in order for NVTOP to display GPU info:
 * For METAX: the *MetaX System Management Library* (*MXSML*) which comes with the GPU driver.
   * This queries the GPU for info.
 * For Enflame: the *Enflame Management Library* (*EFML*) which comes with the GCU driver.
+* For Iluvatar CoreX: the *ixML* runtime library (`libixml.so`) which comes with the driver.
+  * This backend loads the library dynamically at runtime.
