| ### Start the emulator | |
| If you do not already have an instance running, start the emulator: | |
| ```posix-terminal | |
| ffx emu start --headless | |
| ``` | |
| When startup is complete, the emulator prints the following message and | |
| returns: | |
| ```none {:.devsite-disable-click-to-copy} | |
| Logging to "{{ '<var>' }}$HOME{{ '</var>' }}/.local/share/Fuchsia/ffx/emu/instances/fuchsia-emulator/emulator.log" | |
| Waiting for Fuchsia to start (up to 60 seconds)........ | |
| Emulator is ready. | |
