# Mattermost
Mattermost is an open-source team messaging platform, a self-hosted alternative to Slack.
## Dependencies
- **PostgreSQL** - Database for storing messages and team data
## Configuration
Key settings in `config.yaml`:
- **domain** - Where Mattermost will be accessible
- **storage** - Persistent volume size (default: `2Gi`)
- **db.name** - Database name (default: `mattermost`)
## First-Time Setup
1. Add and deploy the app:
```bash
wild app add mattermost
wild app deploy mattermost
```
2. Visit the app URL — on first load you will be prompted to create an administrator account (email + password).
3. After creating the admin account, complete the onboarding wizard to set up your first team.
## Notes
- The setup wizard only runs on first launch
- Email invitations require SMTP to be configured in **System Console → Environment → SMTP**
- Push notifications for mobile apps require a push proxy (or Mattermost Cloud push notification service)
