Open Murmur-0.6.dmg and drag Murmur into Applications.
Open Murmur. macOS will say it can’t check the app (it isn’t notarized yet). Open System Settings → Privacy & Security, scroll down and click Open Anyway.
Allow the microphone and Accessibility when Murmur asks (it needs Accessibility to type into other apps).
On first launch Murmur downloads its two models (about 1.1 GB, once) and prepares them, which takes a few minutes. Until the cleanup model is ready, it types exactly what it heard.
