     4  anywhere. You should be able to take your code and run them without any changes.

     6  ## Creating Lambda Functions
     7  
     8  Creating Lambda functions is not much different than using regular functions, just use
     9  the `lambda-node` runtime.
    10  
    11  ```sh
    12  fn init --runtime lambda-node <DOCKER_HUB_USERNAME>/lambda-node
    13  ```
    14  
    15  Be sure the filename for your main handler is `func.js`.
