+### Parallel Execution with Docker
+To run OSWorld in parallel using Docker, ensure you have Docker installed and configured.
+To install it, follow the section from the OSWorld README on [Docker setup](https://github.com/xlang-ai/OSWorld?tab=readme-ov-file#docker-server-with-kvm-support-for-better-performance).
+Ensure that your docker installation support KVM, as OSWorld requires it for running VMs.
+We also recommend pulling the latest Docker image for OSWorld before running the benchmark:
+
+```bash
+docker pull happysixd/osworld-docker
+```
+
+After setting up Docker, you can change the `use_vmware` parameter in the script to `False` and run:
+
+```bash
+python experiments/run_osworld.py
+```
+You can control number of parallel jobs by setting the `n_jobs` parameter in the script, the default is 4.
+We recommend setting `n_jobs` to `your_number_of_cpu_cores - 2` to leave some resources for the host system and the benchmark itself.
