+# Getting started GPU
+
+Pyccel now supports NVIDIA CUDA, empowering users to accelerate numerical computations on GPUs seamlessly. With Pyccel's high-level syntax and automatic code generation, harnessing the power of CUDA becomes effortless. This documentation provides a quick guide to enabling CUDA in Pyccel
+
+## Cuda Decorator
+
+### kernel
+
+The kernel decorator allows the user to declare a CUDA kernel. The kernel can be defined in Python, and the syntax is similar to that of Numba.
+
+```python
+from pyccel.decorators import kernel
+
+@kernel
+def my_kernel():
+    pass
+
+blockspergrid = 1
+threadsperblock = 1
+# Call your kernel function
+my_kernel[blockspergrid, threadsperblock]()
+
+```
