+  Much of the performance that you'll see depends on your workflow, hardware, and how many name servers the load is spread out on. If you're looking to maximize performance
+  for your workflow/hardware, we recommend starting at 100 threads and increasing until you start to see an increase in domain resolution failures.
+  To help with this, you can use `--output-file=output.jsonl` and `grep -v "NOERROR" output.jsonl | wc -l` to count the number of domains that failed to resolve.
+  Flags that may be of use in tuning performance are:
+
+  * `--timeout` The maximum amount of time ZDNS will spend on a single domain
+  * `--iteration-timeout` The maximum amount of time ZDNS will spend on a single iteration step (ex: resolving google.com at the .com layer)
+  * `--retries` The number of retries ZDNS will make before giving up on a nameserver
+  * `--name-servers` The list of nameservers to use for lookups, mostly useful with `--iterative=false`
