We want to keep the README as small as possible here. Maybe in the documentation Installation guide instead? I'm a bit hesitant though.

Thanks for contributing to the project :)

Is there a reason you're hesitant to add it to the installation guide?

[zanieb]

It's just more content for people to read and it hasn't come up so far.

[joshmcorreia]

It came up for me on a docker container without curl and I created the PR because there wasn't any existing documentation on it. Up to you on if you want to close it or not - at least if someone else faces the same problem as me they'll be able to search "wget" and find this solution.

@joshmcorreia Indeed, I think it's still worth adding possibly as a note in installer.md instead of the repo's README.
