 Tasks can be submitted by calling `ants.Submit(func())`
 ```go
 ants.Submit(func(){})
 ```
 
-## Customizes limited pool
+## Customize limited pool
 `ants` also supports customizing limited pool. You can use the `NewPool` method to create a pool with the given capacity, as following:
 
 ``` go
-// Sets 10000 the size of goroutine pool
+// Set 10000 the size of goroutine pool
 p, _ := ants.NewPool(10000)
-// Submits a task
+// Submit a task
 p.Submit(func(){})
 ```
 
-## Tunes pool capacity
+## Tune pool capacity
 You can change `ants` pool capacity at any time with `ReSize(int)`:
 
 ``` go
-pool.ReSize(1000) // Tunes its capacity to 1000
-pool.ReSize(100000) // Tunes its capacity to 100000
+pool.ReSize(1000) // Tune its capacity to 1000
+pool.ReSize(100000) // Tune its capacity to 100000
 ```
 
 Don't worry about the synchronous problems in this case, this method is thread-safe.

 `ants`支持实例化使用者自己的一个 Pool ，指定具体的池容量；通过调用 `NewPool` 方法可以实例化一个新的带有指定容量的 Pool ，如下：
 
 ``` go
-// Sets 10000 the size of goroutine pool
+// Set 10000 the size of goroutine pool
 p, _ := ants.NewPool(10000)
-// Submits a task

 需要动态调整协程池容量可以通过调用`ReSize(int)`：
 
 ``` go
-pool.ReSize(1000) // Tuning its capacity to 1000
-pool.ReSize(100000) // Tuning its capacity to 100000
+pool.ReSize(1000) // Tune its capacity to 1000
+pool.ReSize(100000) // Tune its capacity to 100000
 ```
 
 该方法是线程安全的。
