 ## Building variants using Docker
 
-Vulkan:
+### Vulkan:
 
 ```shell
 docker build -f docker/Dockerfile.vulkan -t sd .
 ```
 
+### ROCm (AMD GPU):
+
+Defining one or multiple targets with `--build-arg AMDGPU_TARGETS` is strongly recommended.
+Building the image will otherwise likely fail or build for a target that does not fit your
+hardware.
+
+```shell
+# Build for one target
+docker build -f docker/Dockerfile.rocm --build-arg "AMDGPU_TARGETS=gfx1100" -t sd .
+# Build for multiple targets
+docker build -f docker/Dockerfile.rocm --build-arg "AMDGPU_TARGETS=gfx1030;gfx1100" -t sd .
+```
+
 ## Run locally built image's CLI
 
 ```shell
 docker run --rm -v /path/to/models:/models -v /path/to/output/:/output sd [args...]
 # For example
 # docker run --rm -v ./models:/models -v ./build:/output sd -m /models/sd-v1-4.ckpt -p "a lovely cat" -v -o /output/output.png
 ```
+
+### ROCm (AMD GPU)
+
+The user that executes this command needs to be in the `video` group and have read and write
+access to `/dev/dri` and `/dev/kfd`.
+
+`--device` and `--group-add` allow the container access to the GPU.
+
+```shell
+docker run --rm --device=/dev/dri --device=/dev/kfd --group-add video \
+  -v /path/to/models:/models -v /path/to/output/:/output \
+  sd [args...]
+# For example
+# docker run --rm --device=/dev/dri --device=/dev/kfd --group-add video \
+#   -v ./models:/models -v ./build:/output \
+#   sd -m /models/sd-v1-4.ckpt -v -o /output/output.png \
+#   -p "a lovely cat"
+```
