-Advanced settings for workers pools.
+Settings for request pools. These pools are limited on top of `:connections_pool`.
 
 There are four pools used:
 
-* `:federation` for the federation jobs.
-  You may want this pool max_connections to be at least equal to the number of federator jobs + retry queue jobs.
-* `:media` for rich media, media proxy
-* `:upload` for uploaded media (if using a remote uploader and `proxy_remote: true`)
-* `:default` for other requests
+* `:federation` for the federation jobs. You may want this pool's max_connections to be at least equal to the number of federator jobs + retry queue jobs.
+* `:media` - for rich media, media proxy.
+* `:upload` - for proxying media when a remote uploader is used and `proxy_remote: true`.
+* `:default` - for other requests.
 
 For each pool, the options are:
 
-* `:size` - how much workers the pool can hold
+* `:size` - limit to how much requests can be concurrently executed.
 * `:timeout` - timeout while `gun` will wait for response
-* `:max_overflow` - additional workers if pool is under load
+* `:max_waiting` - limit to how much requests can be waiting for others to finish, after this is reached, subsequent requests will be dropped.
