nassh-relay accepts contributions through pull requests on GitHub. After review a pull request should either get merged or be rejected.
When a pull request needs to be reworked, say you have missed something, the pull request is then closed, at the time you finished the required changes you should reopen your original Pull Request and it will then be re-evaluated. At that point if the request is aproved we will then merge it.
Make sure you always rebase your branch on master before submitting pull requests.
