# Install the CLI

> Install tappify, sign in, and confirm the vendor and sandbox project it sees.

`tappify` scaffolds an extension, keeps its types current, serves it while you edit, runs
every check the Tap Store runs, and publishes it. Install it, then sign in.

    One line: your email, your role in the vendor, and the sandbox project — then what to
    run next. If it reports no vendor, run
    [`tappify vendor create`](/extensions/start/create-a-vendor-account).

## Two ways to run every command

Every command works with flags only, for scripts, agents and CI:

```bash theme={null}
tappify extension add widget --name Funnel --page analytics --slot kpi-row --size 2x1
```

or guided, when you leave the flags off:

```bash theme={null}
tappify extension add widget
```

Guided mode asks with select lists. Both produce the same files and the same manifest entry.

Every `tappify extension` and `tappify vendor` command also takes `--json` and prints the
object its human output describes, so an agent reads the result rather than the prose. `tappify ext` is the same command as
`tappify extension`.
