put code here if you want to do a thing.
If you want to add code use a "pull request".
To add like a folder rather than flattened files you have to do it from the command prompt:
cd /path/to/files
git init
git remote add origin https://github.com/Innoviox/pico-ctf
git add .
git commit "message"
git push -uf origin master
