👋 Hi! Thank you for contributing to the vLLM project.
Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can do one of these:

• Add ready label to the PR
• Enable auto-merge.

🚀

Looks good. Thanks @rafvasq

Actually, I think bash is what you're looking for. console is intended to be used for terminal sections, and thus commands should be prefixed by the user/cwd, e.g. user@abc:~/vllm$

That's true @DarkLight1337, although in this case these commands are meant to be run in terminal, so I updated the commands to include a prompt symbol $ similar to how they're shown here

LGTM now!
