When you're done with developing your mod it's time to release it!
Push all your code/assets to a GitHub repo and create a new release, see this tutorial for help.
When you've published your mod on ParkitectNexus.com. The client will make a request to GitHub and checks all releases on the repository, it will download the latest created release. This means that you can choose your own version numbering style. A best practice is to use the Semantic Versioning style, which means that you use 3 numbers, 1.2.3. Where 1 is a major overhaul, 2 minor changes and 3 is revisions (bug fixes).
See this page on how to release your mod on ParkitectNexus
Please make sure there aren't any copyrighted game assets or dll's in your repository.
