Try it: https://shiro.computer
For interactive demos showing npm install, node execution, and git workflows -- running live in Shiro, not recordings -- see https://shiro.computer/show

P.S. `curl -fsSL https://claude.ai/install.sh | bash` works. You can run real Claude Code and it can use Shiro's tools like a normal Linux system.
