Fork the hello world bot template at https://github.com/tpinecone/hello-world-bot/
By forking the hello world bot template, you'll be able to keep your bot and the changes you make to it separate from the original template repo.
What did we just do?
When you "fork" a GitHub repository, you're taking a project someone else has written (in this case, the hello-world-bot template), and creating a copy of it that you can make changes to. The changes you make on your fork won't affect the original repository. You can read more about forking here.
