Getting help

Ask a thread. Its agent knows where this guide is and can read it, or look at the code and tell you how something works.
Ask a thread to run tb status, which says what the runner is doing: its version, the threads that are busy, and any restart or update on the way.
threadbear in Terminal opens the app, and quitting it with ⌘Q is always safe, since your threads keep running without it. If the app says it can't reach the runner, click Start runner.
