I just finished to write the tutorial for creating new runtimes with ActionLoop, that is writing a simple read/write loop in the target language. A runtime can be developed in a matter of a few hours.
Here is the draft https://github.com/sciabarracom/incubator-openwhisk/blob/actionloop-documentation/docs/actions-actionloop.md If you have suggestions or comments on it please let me know before I submit the PR. -- Michele Sciabarra [email protected]
