# Activate Application

The `activate` command enables your ZeyOS application in the current instance, making it accessible.

```bash
zeysdk activate [options]
```

**Options**

| Option | Description |
|--------|-------------|
| `--verbose` | Show detailed output |

**Process**

1. **Validation**
   - Checks for sync.json
   - Validates configuration
   - Verifies authentication

2. **Activation**
   - Sets app activity to active
   - Updates platform state
   - Confirms activation

**Error Handling**

| Error | Description | Resolution |
|-------|-------------|------------|
| Missing sync.json | Configuration not found | Run `zeysdk link` |
| Invalid config | Missing required fields | Check sync.json |
| Auth failed | Invalid token | Re-link application |

**Notes**

- Activation is immediate
- All users regain access
- Previous settings restored
- Use after maintenance or updates

**Best Practices**

- Confirm the active instance with `zeysdk whoami` before activation
- Activate after validating recent changes in a staging instance
- Notify users when re-enabling a previously unavailable app
- Use `zeysdk compare` before activation if remote state may be stale
