## Managing Plugins

### Via Admin Panel

1. Go to **Admin** → **Plugins**
2. View installed plugins
3. Enable/disable as needed
4. Configure plugin settings

### Via API

```bash
# List plugins
curl -H "Authorization: Bearer $TOKEN" \
  http://localhost:3000/api/plugins/defaults

# Enable plugin
curl -X POST -H "Authorization: Bearer $TOKEN" \
  http://localhost:3000/api/plugins/instance/voting.quadratic

# Disable plugin
curl -X DELETE -H "Authorization: Bearer $TOKEN" \
  http://localhost:3000/api/plugins/instance/voting.quadratic
```

## Voting Method Configuration

### Platform Level
Enable/disable voting methods for the entire instance:

```bash
# List available methods
curl http://localhost:3000/api/voting-methods

# Enable a method
curl -X PUT -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"is_active": true}' \
  http://localhost:3000/api/voting-methods/quadratic
```

### Community Level
Communities can configure which enabled methods they use:

```bash
# Set community voting methods
curl -X PUT -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"methods": ["schulze", "approval"]}' \
  http://localhost:3000/api/communities/{id}/voting-methods
```

## Plugin Security

### Signed Plugins
For third-party plugins, require signatures:
- Instance setting: `require_signed_plugins: true`
- Validates plugin authenticity

### Capabilities
Plugins request specific capabilities:
- Database access (read/write)
- Outbound HTTP
- Background jobs
- UI components

## Developing Plugins

See the [Plugin Development Guide](../reference/plugin-development.md) for creating custom plugins.
