As we were looking into the WildFly repository, we realized that we don't have a CONTRIBUTING.md file that can help the new contributors with contribution guidelines for our project.

It appears to be that we already have a similar kind of document present inside the repo here. But as a best OSS practice, the WildFly repo should have a separate CONTRIBUTING.md file and we should also add good first issue filter there.

So, my idea is to create a new fresh document and combine everything together and put it as CONTRIBUTING.md at the repository's root. We have a Jira issue to take care of it.

Please let me know what you think about this.
