+## Concurrency
+
+- When `mode` is set to `null` (default), concurrency is disabled.
+- When `mode` is set to 'task', each task's iterations run concurrently.
+- When `mode` is set to 'bench', different tasks within the bench run concurrently

+```ts
+// options way (recommended)
+bench.threshold = 10 // The maximum number of concurrent tasks to run. Defaults to Infinity.
+bench.concurrency = "task" // The concurrency mode to determine how tasks are run.  
+await bench.run()
+
+// standalone method way
+await bench.runConcurrently(10, "task") // with runConcurrently, mode is set to 'bench' by default
+```
+
+The first way of doing concurrency also affects `bench.warmup` and makes it concurrent too.
