     3  ## Which languages are supported?
     4  
     5  Since we use containers as the base building block, all languages can be used. There may not be higher level 
     6  helper libraries like our Lambda wrapper for every language, but you can use any language if you follow the 
     7  base [function format](function-format.md).

     9  ## Where can I run IronFunctions?
    10  
    11  Anywhere. Any cloud, on-premise, on your laptop. As long as you can run a Docker container, you can run IronFunctions.

    13  ## Which orchestration tools does IronFunctions support?

    15  IronFunctions can be deployed using any orchestration tool. Here are some examples:

    19  ## Does IronFunctions require Docker?
    20  
    21  For now we require Docker primarily for the packaging and distribution via Docker Registries, 
    22  but we've built IronFunctions in a way that abstracts the container technology so we can support others as
    23  needed. For instance, we'll eventually add rkt support.
