it would be good to include a mention of num_workers in the LocalDaskExecutor page. Many might assume pool=ThreadPool(100) as a parameter might work without looking at the code.

Hi Rob. I don't work for Prefect, but in my experience the maintainers are very receptive to contributions that fix or improve things, including the documentation. I'm not sure which page you're referring to, but many of the docs at docs.prefect.io can be found here: https://github.com/PrefectHQ/prefect/tree/master/docs Consider submitting a pull request there

yes I agree, I'll do an merge request for a few things when I get some of my code working. Small items.
