+## 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
+
+This will not work for all unsupported GPUs.  Reach out on [Discord](https://discord.gg/ollama)
+or file an [issue](https://github.com/ollama/ollama/issues) for additional help.
+
+
+## Installing older versions on Linux
+
+If you run into problems on Linux and want to install an older version you can tell the install script
+which version to install.
+
+```sh
+curl -fsSL https://ollama.com/install.sh | OLLAMA_VERSION="0.1.27" sh
