This project is intended to be a sandbox for our team to try out and become comfortable with Java 11 and prepare for the certifications.
- Create a Github account
- Clone the project to your local
- Add your home package to the project ex. src/main/java/thefungiz/javacert
- Add a Runner class that has a main method that prints out a message
- Add a README.md file to your home. This will be a place to put notes
- Commit and push
*.md files use markdown syntax and allow you to style your notes. A full description of the markdown syntax can be found here - https://www.markdownguide.org/basic-syntax/
