-  Sentry uses `hackney <https://github.com/benoitc/hackney>`_.  If you would like to set `options <https://github.com/benoitc/hackney/blob/master/doc/hackney.md#request5>`_ for hackney requests, they can be provided via this configuration.
+  Sentry starts its own hackney pool named ``:sentry_pool``, and defaults to using it.  Hackney's ``pool`` configuration as well others like proxy or response timeout can be set through this configuration as it is passed directly to hackney when making a request.
