You can configure redirects and rewrite rules for your Netlify site by adding a `_redirectsfile` to the root of your site folder. This file should be deployed along with your build command, not just placed in the repository's root. For more information on what can be done with the `_redirects` file, you can refer to the documentation and try out test rules at Netlify's playground environment. The founder of OpenSauced, Brian Douglas, is mentioned as having expertise in this area.
