I am installing Railgun. And it said I need to install Cloudflare Package from https://pkg.cloudflare.com/, via the following command:
sudo rpm -ivh http://pkg.cloudflare.com/cloudflare-release-latest.el<VERSION>.rpm
But, how to know the latest version so that I can put it to ? On https://pkg.cloudflare.com/, there are no information but only two examples of version 6 and 7.
Also it seems that I do not need to install the GPG key manually, by installing the rpm package, the GPG key will be installed automatically. Is that correct?
