Submitting a Challenge

When adding a new challenge, please follow these steps:

Note: In this example, the challenge's name is Hello Friend and it is a Stego challenge.

1. Fork this repo to your own account by clicking the Fork button at the top-right of the screen (your fork will stay private).
2. Clone your repo locally (git clone [email protected]:my_github_username/SunshineCTF-2019-Private.git && cd SunshineCTF-2019-Private)
3. Create a git branch with the name of the challenge (git checkout -b hello-friend).
4. Create your challenge directory and the source files.
5. Stage your challenge files to be committed (git add Stego/Hello-Friend && git status).
6. Commit your changes (git commit -m 'Added Hello Friend challenge')
7. Push the branch you created to your fork (git push -u origin hello-friend)
8. Back on the GitHub website for your fork, there should be a new button to create a pull request from the hello-friend branch on your repo to the upstream repo (the one on HackUCF's GitHub). Click that, fill out the details, and submit your pull request.
