+## Run workflow locally
+
+Requirements:
+- Docker
+- NVIDIA container toolkit
+- [act](https://nektosact.com/)
+
+Make sure following command works:
+```shell
+docker run --rm --runtime=nvidia --gpus all ubuntu nvidia-smi
+```
+
+Run workflow with:
+```shell
+act \
+-P ubuntu-latest=nvidia/cuda:12.8.1-devel-ubuntu24.04 \
+--container-options "--runtime=nvidia --gpus all" \
+-W .github/workflows/self_hosted_ci.yml
+# Should run nvdia-smi, compile with nvcc and run the compiled executable
+```
+(If your workflow does not use `runs-on: ubuntu-latest` then update the `-P` option accordingly.)
+(Match the nvidia/cuda image tag with the cuda version reported by `nvidia-smi`)
