# 1. Copy this file to the root of your repository, then rename it to '.travis.yml'
# 2. Replace 'YOUR NAME' and 'YOUR EMAIL'
# 3. Create "Environment Variables" in travis. Make sure to not show them in the output.
#     - FTP_USER: The username for FTP transfer.
#     - FTP_PASSWORD: Password for the user.
# 4. Replace "DOMAIN.TLD" with your FTP domain and maybe the path where to put things.
