+Installing fVDB
+================================================================
+
+fVDB depends on `PyTorch <https://pytorch.org/>`_,
+and requires a CUDA-capable GPU. Below are the supported sofware and hardware configurations.
+
+Software Requirements
+------------------------
+
+fVDB is currently supported on the matrix of dependencies in the following table.
+
++------------------+-----------------+-----------------+----------------+------------------------------------------+
+| Operating System | PyTorch Version | Python Version  | CUDA Version   | Vulkan Version (only for visualization)  |
++------------------+-----------------+-----------------+----------------+------------------------------------------+
+| Linux Only       | 2.9.0           | 3.10 - 3.13     | 12.8 - 13.0    | 1.3.275.0                                |
++------------------+-----------------+-----------------+----------------+------------------------------------------+
+
+Driver and Hardware Requirements
+-----------------------------------
+
+The following table specifies the minimum NVIDIA driver versions and GPU architectures needed to run fVDB-Reality-Capture:
+
++------------------+----------------+------------------+---------------------+
+| Operating System | Driver Version | GPU Architecture | Comptue Capability  |
++------------------+----------------+------------------+---------------------+
+| Linux Only       | 550.0 or later | Ampere or later  | 8.0 or greater      |
++------------------+----------------+------------------+---------------------+
+
+
+Installation from pre-built wheels
+-------------------------------------
+To get started, run the appropriate pip install command for your Pytorch/CUDA versions. This command will install
+the correct version of `fvdb-core` if it is not already installed.
+
+
+PyTorch 2.9.0 + CUDA 12.8
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. code-block:: bash
+
+    pip install fvdb-reality-capture fvdb-core==0.3.0+pt29.cu128 --extra-index-url="https://d36m13axqqhiit.cloudfront.net/simple" torch==2.9.0 --extra-index-url https://download.pytorch.org/whl/cu128
+
+
+PyTorch 2.9.0 + CUDA 13.0
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. code-block:: bash
+
+    pip install fvdb-reality-capture fvdb-core==0.3.0+pt29.cu130 --extra-index-url="https://d36m13axqqhiit.cloudfront.net/simple" torch==2.9.0 --extra-index-url https://download.pytorch.org/whl/cu130
+
+
+
+
+Installation from source
+-----------------------------
+
+Clone the [fvdb-core repository](https://github.com/openvdb/fvdb-core).
+
+.. code-block:: bash
+
+   git clone git@github.com:openvdb/fvdb-core.git
+
+Next build and install the fVDB library
+
+.. code-block:: bash
+
+   pushd fvdb-core
+   ./build.sh install verbose editor_force
+   popd
