# Setup — Herald

Follow [Create and manage Bots](https://docs.x.ai/grok-bot/bots) and [Skills and routines](https://docs.x.ai/grok-bot/skills-routines-and-automations).

1. In Grok Bot: **New** → **Create new agent**.
2. Open **Bot actions → Edit Profile**. Set **Name** to `Herald`, **Title** to `Email Newsletter Builder`.
3. Paste the **Description** from the PROFILE section of the export file (durable rules only).
4. **Settings → Plugins**: connect these connectors / MCPs (swap for tools you actually have):
- Mailchimp
- Google Analytics
5. Send the **First task** from the export file.
6. When the Bot is solid: ask it to **pack itself**, publish the share link, then others can **Add to Grok Bot** from that link (xAI share flow).

Strip secrets before sharing. Adding a shared Bot accepts third-party bot terms.
