+## AMD Radeon GPU Support
+
+Ollama leverages the AMD ROCm library, which does not support all AMD GPUs. In
+some cases you can force the system to try to use a close GPU type.  For example
+The Radeon RX 5400 is `gfx1034` (also known as 10.3.4) however, ROCm does not
+support this patch-level, the closest support is `gfx1030`.  You can use the
+environment variable `HSA_OVERRIDE_GFX_VERSION` with `x.y.z` syntax.  So for
+example, to force the system to run on the RX 5400, you would set
+`HSA_OVERRIDE_GFX_VERSION="10.3.0"` as an environment variable for the server.
+
+At this time, the known supported GPU types are the following: (This may change from
+release to release)
+- gfx900
+- gfx906
+- gfx908
+- gfx90a
+- gfx940
+- gfx941
+- gfx942
+- gfx1030
+- gfx1100
+- gfx1101
+- gfx1102

-# Example Modelfile - Tweetwriter
-
-This simple examples shows what you can do without any code, simply relying on a Modelfile. The file has two instructions:
-
-1. FROM - The From instructions defines the parent model to use for this one. If you choose a model from the library, you can enter just the model name. For all other models, you need to specify the namespace as well. You could also use a local file. Just include the relative path to the converted, quantized model weights file. To learn more about creating that file, see the `import.md` file in the docs folder of this repository.
-2. SYSTEM - This defines the system prompt for the model and overrides the system prompt from the parent model.
-
-## Running the Example
-
-1. Create the model:
-
-   ```bash
-   ollama create tweetwriter
-   ```
-
-2. Enter a topic to generate a tweet about.
-3. Show the Modelfile in the REPL.
-
-   ```bash
-   /show modelfile
-   ```
-
-   Notice that the FROM and SYSTEM match what was in the file. But there is also a TEMPLATE and PARAMETER. These are inherited from the parent model.
