```bash
# Start the debugger
$ dlv debug --headless .
API server listening at: 127.0.0.1:34241
$ dlv debug --headless --api-version=2 --listen=127.0.0.1:43000 .
API server listening at: 127.0.0.1:43000

# Connect to it from another terminal
$ dlv connect 127.0.0.1:34241
$ dlv connect 127.0.0.1:43000
```

Note that the default port used will vary on your system and per run, so
actually watch out what address the first `dlv` run tells you to connect to.
If you do not explicitly supply the `--listen` flag, the port used will vary
per run, so passing this in makes the debugger easier to use from a script
or your IDE of choice.

Additionally, we pass in `--api-version=2` because delve defaults to version 1
for backwards compatibility reasons. However, delve recommends using version 2
for all new development and some clients may no longer work with version 1.
For more information, see the [Delve documentation](https://github.com/go-delve/delve/tree/master/Documentation/api).
