+# JAX Builds on ROCm
+This directory contains files and setup instructions t0 build and test JAX for ROCm in Docker environment. You can build, test and run JAX on ROCm yourself!
+***
+### Build JAX-ROCm in docker
+
+1.  Install Docker: Follow the [instructions on the docker website](https://docs.docker.com/engine/installation/).
+
+  2. Build JAX by running the following command from JAX root folder.
+
+    ./build/rocm/ci_build.sh --keep_image bash -c "./build/rocm/build_rocm.sh"
+
+  3. Launch a container: If the build was successful, there should be a docker image with name "jax-rocm:latest" in list of docker images (use "docker images" command to list them).
+  ```
+  sudo docker run -it --device=/dev/kfd --device=/dev/dri --security-opt seccomp=unconfined --group-add video --entrypoint /bin/bash jax-rocm:latest
+  ```
+
+***
+### Build and Test JAX-ROCm in docker (suitable for CI jobs)
+This folder has all the scripts necessary to build and run tests for JAX-ROCm.
+The following command will build JAX on ROCm and run all the tests inside docker (script should be called from JAX root folder).
+```
+./build/rocm/ci_build.sh bash -c "./build/rocm/build_rocm.sh&&./build/rocm/run_single_gpu.py&&build/rocm/run_multi_gpu.sh"
