Rollup can be configured using a YAML file. By default, it looks for `rollup.yml` in the current directory. You can specify a different configuration file using the `--config` flag. Rollup can be configured using a YAML file. By default, it looks for `rollup.yml` in the current directory. You can specify a different configuration file using the `--config` flag.
Example `rollup.yml`: **Scrape Configuration Parameters:**
- `requests_per_second`: *(float, optional)* The rate at which requests are made per second during web scraping. Default is `1.0`.
- `burst_limit`: *(integer, optional)* The maximum number of requests that can be made in a burst. Default is `5`.
These parameters help control the request rate to avoid overloading the target servers and to comply with their rate limits.
**Example `rollup.yml` with Scrape Configuration:**
```yaml ```yaml

- go requests_per_second: 1.0
