By taking delivery of the SOFTWARE, you affirm that you have reached the legal age of majority, you accept the terms of this license, and you take legal and financial responsibility for the actions of your permitted users. 
+
+You agree to use the SOFTWARE only for purposes that are permitted by (a) this license, and (b) any applicable law, regulation or generally accepted practices or guidelines in the relevant jurisdictions.
+
+1. LICENSE. Subject to the terms of this license, NVIDIA grants you a non-exclusive limited license to: (a) install and use the SOFTWARE, and (b) distribute the SOFTWARE subject to the distribution requirements described in this license. NVIDIA reserves all rights, title and interest in and to the SOFTWARE not expressly granted to you under this license.
+
+2. DISTRIBUTION REQUIREMENTS. These are the distribution requirements for you to exercise the distribution grant: 
+a.  The terms under which you distribute the SOFTWARE must be consistent with the terms of this license, including (without limitation) terms relating to the license grant and license restrictions and protection of NVIDIA's intellectual property rights. 
+b.  You agree to notify NVIDIA in writing of any known or suspected distribution or use of the SOFTWARE not in compliance with the requirements of this license, and to enforce the terms of your agreements with respect to distributed SOFTWARE. 
+
+3. LIMITATIONS. Your license to use the SOFTWARE is restricted as follows:
+a.  The SOFTWARE is licensed for you to develop applications only for use in systems with NVIDIA GPUs.

+
+7. FEEDBACK. You may, but don't have to, provide to NVIDIA any Feedback.

IN NO EVENT WILL NVIDIA'S AND ITS AFFILIATES TOTAL CUMULATIVE LIABILITY UNDER OR ARISING OUT OF THIS LICENSE EXCEED US$10.00. THE NATURE OF THE LIABILITY OR THE NUMBER OF CLAIMS OR SUITS SHALL NOT ENLARGE OR EXTEND THIS LIMIT. 
+
+10. TERMINATION. Your rights under this license will terminate automatically without notice from NVIDIA if you fail to comply with any term and condition of this license or if you commence or participate in any legal proceeding against NVIDIA with respect to the SOFTWARE. NVIDIA may terminate this license with advance written notice to you if NVIDIA decides to no longer provide the SOFTWARE in a country or, in NVIDIA's sole discretion, the continued use of it is no longer commercially viable. Upon any termination of this license, you agree to promptly discontinue use of the SOFTWARE and destroy all copies in your possession or control. Your prior distributions in accordance with this license are not affected by the termination of this license.

+# CUDA-Python
+
+CUDA Python is a standard set of low-level interfaces, providing full coverage of and access to the CUDA host APIs from Python. Checkout the [Overview](https://nvidia.github.io/cuda-python/overview.html) for the workflow and performance results.
+
+## Installing
+
+CUDA Python can be installed from:
+
+* PYPI
+* Conda (nvidia channel)
+* Source builds
+
+There're differences in each of these options that are described further in [Installation](https://nvidia.github.io/cuda-python/install.html) documentation. Each package will guarantee minor version compatibility.
+
+## Runtime Dependencies
+
+CUDA Python is supported on all platforms that CUDA is supported. Specific dependencies are as follows:
+
+* Driver: Linux (450.80.02 or later) Windows (456.38 or later)
+* CUDA Toolkit 12.0 to 12.6
+
+Only the NVRTC redistributable component is required from the CUDA Toolkit. [CUDA Toolkit Documentation](https://docs.nvidia.com/cuda/index.html) Installation Guides can be used for guidance. Note that the NVRTC component in the Toolkit can be obtained via PYPI, Conda or Local Installer.
+
+### Supported Python Versions
+
+CUDA Python follows [NEP 29](https://numpy.org/neps/nep-0029-deprecation_policy.html) for supported Python version guarantee.
+
+Before dropping support, an issue will be raised to look for feedback.
+
+Source builds work for multiple Python versions, however pre-build PyPI and Conda packages are only provided for a subset:
+
+* Python 3.9 to 3.12
+
+## Testing
+
+### Requirements
+
+Latest dependencies can be found in [requirements.txt](https://github.com/NVIDIA/cuda-python/blob/main/requirements.txt).
+
+### Unit-tests
+
+You can run the included tests with:
+
+```
+python -m pytest
+```
+
+### Benchmark
+
+You can run benchmark only tests with:
+
+```
+python -m pytest --benchmark-only
+```
+
+### Samples
+
+You can run the included tests with:
+
+```
+python -m pytest examples
+```
+
+## Examples
+
+CUDA Samples rewriten using CUDA Python are found in `examples`.
+
+Custom extra included examples:
+
+- `examples/extra/jit_program_test.py`: Demonstrates the use of the API to compile and
+  launch a kernel on the device. Includes device memory allocation /
+  deallocation, transfers between host and device, creation and usage of
+  streams, and context management.
+- `examples/extra/numba_emm_plugin.py`: Implements a Numba External Memory Management
+  plugin, showing that this CUDA Python Driver API can coexist with other
+  wrappers of the driver API.
