+          notices within Derivative Works that You distribute, alongside

+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# bellman-cuda
+
+[![Logo](eraLogo.svg)](https://zksync.io/)
+
+zkSync Era is a layer 2 rollup that uses zero-knowledge proofs to scale Ethereum without compromising on security or
+decentralization. Since it's EVM compatible (Solidity/Vyper), 99% of Ethereum projects can redeploy without refactoring
+or re-auditing a single line of code. zkSync Era also uses an LLVM-based compiler that will eventually let developers
+write smart contracts in C++, Rust and other popular languages.
+
+bellman-cuda is a library implementing GPU-accelerated cryptographic functionality for the zkSync prover. 
+
+### Building the library
+The library can be build by executing these steps:
+
+#### Initialize git submodules
+`git submodule update --init --recursive`
+#### Generate the build configuration by executing
+`cmake -B./build -DCMAKE_BUILD_TYPE=Release`
+#### Build the binary by executing
+`cmake --build ./build`
+
+The library binary can be found in the `./build/src` folder. Change the path in the above commands if a different build location is desired.
+
+By default, the library is build for Compute Architecture 8.0.
+If a different Compute Architecture is required, the [CMAKE_CUDA_ARCHITECTURES](https://cmake.org/cmake/help/latest/variable/CMAKE_CUDA_ARCHITECTURES.html) variables can be set to the desired architecture(s) during the build configuration generation step.
+
+Example for Compute Architecture 8.6: 
+```
+cmake -B./build -DCMAKE_BUILD_TYPE=Release -DCMAKE_CUDA_ARCHITECTURES=86
+```
+
+### Executing Tests
+By default, the tests binary is not compiled.
+
+This can be changed by setting the variable `BUILD_TESTS` to `ON` in the build configuration step like this:
+
+`cmake -B./build -DCMAKE_BUILD_TYPE=Release -DBUILD_TESTS=ON`.
+
+Then, after executing the build step, the tests binary is located in the `./build/tests` folder and can be executed by calling:
+
+`./build/tests/tests`.  
+
