 CUDA (optional)
 ^^^^^^^^^^^^^^^
 
-CUDA is optional but highly recommended. By default, Xmipp will search for your CUDA installation, but you can assign the nvcc exe file in the configuration file with the variable CMAKE_CUDA_COMPILER, is also possible setting the variable XMIPP_CUDA_BIN in the scipion `configuration file <https://scipion-em.github.io/docs/release-3.0.0/docs/scipion-modes/scipion-configuration.html>`_. To assign a specific compiler for CUDA set the variable CMAKE_CUDA_HOST_COMPILER in the configuration file. For more details visit the `configuration page <https://i2pc.github.io/docs/Utils/ConfigurationF/index.html#configuration-file>`_
+By default, Xmipp attempts to automatically detect a CUDA installation. Manual configuration is possible if needed. 
+
+To activate/deactivate CUDA compilation:
+- XMIPP_USE_CUDA (xmipp.conf)
+- XMIPP3_XMIPP_USE_CUDA (environment)
+
+To specify the CUDA compiler (nvcc):
+- CMAKE_CUDA_COMPILER (xmipp.conf)
+- XMIPP_CUDA_BIN (`Scipion configuration file <https://scipion-em.github.io/docs/release-3.0.0/docs/scipion-modes/scipion-configuration.html>`_)
+- XMIPP3_CMAKE_CUDA_COMPILER (environment)
+
+To define a specific host compiler:
+- CMAKE_CUDA_HOST_COMPILER (xmipp.conf)
+- XMIPP3_CMAKE_CUDA_HOST_COMPILER (environment)
+
+To manually set CUDA libraries path:
+- XMIPP_CUDA_LIB (`Scipion configuration file <https://scipion-em.github.io/docs/release-3.0.0/docs/scipion-modes/scipion-configuration.html>`_)
+
+Refer to the `configuration page <https://i2pc.github.io/docs/Utils/ConfigurationF/index.html#configuration-file>`_ for additional details.
