+# Dynamo Support Matrix
+
+This document provides the support matrix for Dynamo, including hardware, software and build instructions.
+
+## Hardware Compatibility
+
+
+| **CPU Architecture**  | **Status**    |
+|-----------------------|---------------|
+| **x86_64**            | Supported     |
+| **ARM64**             | Experimental  |
+
+> **Note**: While **x86_64** architecture is supported on systems with a minimum of 32 GB RAM and at least 4 CPU cores. The **ARM64** support is experimental and may have limitations.
+
+### GPU Compatibility
+
+If you are using a **GPU**, the following GPU models and architectures are supported:
+
+| **GPU Architecture**                | **Status**    |
+|-------------------------------------|---------------|
+| **NVIDIA Blackwell Architecture**   | Supported     |
+| **NVIDIA Hopper Architecture**      | Supported     |
+| **NVIDIA Ada Lovelace Architecture**| Supported     |
+| **NVIDIA Ampere Architecture**      | Supported     |
+
+## Platform Architecture Compatibility
+
+**Dynamo** is compatible with the following platforms:
+
+| **Operating System**   | **Architecture**   | **Status**              |
+|------------------------|--------------------|-------------------------|
+| **Linux**              | x86_64             | Supported               |
+| **Linux**              | ARM64              | Experimental            |
+
+> **Note**: For **Linux**, the **ARM64** support is experimental and may have limitations.
+
+## Software Compatibility
+
+| **Dependency**   | **Version** |
+|------------------|-------------|
+|**Base Container**|    25.01    |
+| **vLLM**         |0.7.2+dynamo*|
+|**TensorRT-LLM**  |    0.19.0** |
+|**NIXL**          |    0.1.0    |
+
+> **Note**:
+> - *v0.7.2+dynamo is a customized patch of v0.7.2 from vLLM.
+> - **The specific version of TensorRT-LLM (planned v0.19.0) that will be supported by Dynamo is subject to change.
+
+
+## Build Support
+**Dynamo** currently provides build support in the following ways:
+
+- **Wheels**: Pre-built Python wheels are only available for **x86_64 Linux**. No wheels are available for other platforms at this time.
+- **Container Images**: We distribute only the source code for container images, and only **x86_64 Linux** is supported for these. Users must build the container image from source if they require it.
+
+Once you've confirmed that your platform and architecture are compatible, you can install **Dynamo** by following the instructions in the [Quick Start Guide](https://github.com/ai-dynamo/dynamo/?tab=readme-ov-file#quick-start).
