-## `--data` <<directory>>
-
-default: **.**
-
-The directory where Bytebase stores its own data if [`--pg`](#pg-string) is not specified. The directory must exist beforehand, otherwise Bytebase will fail to start. If <<directory>> is a relative path, then it's relative to the directory where the bytebase binary runs.
-
-## `--debug`
-
-default: **false**
-
-If specified, Bytebase will emit more logs, this is only used when troubleshooting Bytebase issues.
-
-## `--disable-metric`
-
-default: **false**
-
-If specified, Bytebase will not collect usage metric.
-
-## `--disable-sample`
-
-default: **false**
-
-If specified, Bytebase will not start sample Postgres instance.
-
-## `--demo` <<string>>
-
-default: **""**
-
-The demo name. If specified, Bytebase will load the demo data instead of the real data. The data is the same used by [the demo](https://www.bytebase.com/view-live-demo). This is a quick way to test the product yourself or demonstrate it to your peers. When Bytebase is started with `--demo`, it stores the data in a separate location, which means the demo data and real data never interferes with each other.

-The current available demo names are:
