## Submits tasks ## Submit tasks
Tasks can be submitted by calling `ants.Submit(func())` Tasks can be submitted by calling `ants.Submit(func())`
```go ```go
ants.Submit(func(){}) 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: `ants` also supports customizing limited pool. You can use the `NewPool` method to create a pool with the given capacity, as following:
