 Building from Source
 ^^^^^^^^^^^^^^^^^^^^
 
-Prerequisites
-~~~~~~~~~~~~~
-
-Before building CUDA-QX from source, ensure your system meets the following requirements:
-
-* **CUDA-Q**: The NVIDIA quantum-classical programming model
-* **CMake**: Version 3.28 or higher (``pip install "cmake<4"``), less than 4.0
-* **GCC**: Version 11 or higher
-* **Python**: Version 3.10, 3.11, 3.12, or 3.13
-* **NVIDIA GPU**: CUDA-capable GPU with compute capability 7.0 or higher
-* **Git**: For cloning the repository
-
-Build Instructions
-~~~~~~~~~~~~~~~~~~~
-
-1. Clone the repository:
-
-.. code-block:: bash
-
-    git clone https://github.com/nvidia/cudaqx
-    cd cudaqx
-
-2. Create and enter build directory:
-
-.. code-block:: bash
-
-    mkdir build && cd build
-
-3. Configure with CMake:
-
-.. code-block:: bash
-
-    cmake .. -G Ninja \
-        -DCUDAQX_ENABLE_LIBS="all" \
-        -DCUDAQX_INCLUDE_TESTS=ON \
-        -DCUDAQX_BINDINGS_PYTHON=ON \
-        -DCUDAQ_DIR=$HOME/.cudaq/lib/cmake/cudaq \
-        -DCMAKE_CXX_FLAGS="-Wno-attributes" \
-        -DCMAKE_BUILD_TYPE=Release \
-        -DCMAKE_INSTALL_PREFIX=$HOME/.cudaqx
-
-4. Build and install:
-
-.. code-block:: bash
-
-    ninja install
-
-CMake Build Options
-~~~~~~~~~~~~~~~~~~~~
-
-* ``CUDAQX_ENABLE_LIBS``: Specify which libraries to build (``all``, ``qec``, ``solvers``)
-* ``CUDAQX_INCLUDE_TESTS``: Enable building of tests
-* ``CUDAQX_BINDINGS_PYTHON``: Enable Python bindings
-* ``CUDAQ_DIR``: Path to CUDA-Q installation
-* ``CMAKE_INSTALL_PREFIX``: Installation directory
-
-Verifying Installation
------------------------
-
-To verify your installation, run the following Python code:
-
-.. code-block:: python
-
-    import cudaq_qec as qec
-    import cudaq_solvers as solvers
-
-
-Troubleshooting (Common Issues)
---------------------------------
-
-1. **CMake configuration fails**:
-    * Ensure CUDA-Q is properly installed
-    * Verify CMake version (``cmake --version``)
-    * Check GCC version (``gcc --version``)
-
-2. **CUDA device not found**:
-    * Verify NVIDIA driver installation
-    * Check CUDA toolkit installation
-    * Ensure GPU compute capability is supported
-
-3. **Python bindings not found**:
-    * Confirm ``CUDAQX_BINDINGS_PYTHON=ON`` during build
-    * Check Python environment activation
-    * Verify installation path is in ``PYTHONPATH``
