# Create and configure an agent

> Set up your Founding Agent in the portal: identity, voice, teaching, and deploy.

Create and configure your agent in the portal at [https://portal.usemoss.dev/fa](https://portal.usemoss.dev/fa).

## The create wizard

<Steps>
  <Step title="Identify">
    Enter your company name. Your agent slug is derived from it and cannot be changed later, so choose carefully. Enter your website URL, which seeds your initial list of allowed domains.
  </Step>

  <Step title="Voice">
    Set the greeting your agent speaks at the start of each call, the exit message it speaks when ending a call, and any extra instructions that shape its tone and behavior. These instructions apply to every conversation.
  </Step>

  <Step title="Teach">
    Optionally add question-and-answer pairs now to give your agent its first round of knowledge. You can skip this step and come back later from the [Teach](/docs/founding-agent/portal/teach) tab.
  </Step>

  <Step title="Deploy">
    The portal shows your publishable key, your API key, and an embed snippet. Copy these before leaving this screen.
  </Step>
</Steps>

<Warning>
  Your API key is shown only once: at creation and again when you rotate it. Store it in a secret manager immediately. If you lose it, rotate it from the Config tab to generate a new one.
</Warning>

## Edit configuration later

After creation, open the agent and go to the Config tab. From there you can update:

* Name and description
* Greeting and exit message
* Extra instructions
* Allowed domains

Allowed domains control which origins can embed the agent. Use `*` to allow any origin, or `*.example.com` to allow all subdomains of a specific domain. You can add, edit, and remove domain entries at any time.

The Config tab also includes a booking toggle. When booking is enabled, your agent can offer to book a meeting. See [Booking](/docs/founding-agent/embed/booking) for setup details.
