how do i install this thing?

As far as I understand, you don't. You open Claude Code inside the repo and prompt `boot llmunix` inside Claude Code. The CLAUDE.md file tells Claude how to respond to that.

Thank you for the hint. I guess I need a claude API token. From the images it seems he is opening it from his default directory. I sees the 'base env' so it is unclear if any other packages were installed beyond the default linux. I see he simply typed 'boot llmunix' so he must have symlinked 'boot' to his PATH.
