## Config

# Under Windows+WSL you'll want to use .exe here.
# Since that's what I use personally it's the default.
# Remove the '.exe' extension to use your native Linux cloudflared binary.
cloudflared_bin = "cloudflared.exe"
# (Or if you're feeling in an extra spicy mood, change it to "docker run --network host erisamoe/cloudflared")
#   (But I don't really recommend that)

## End of config
