Auto merge of #206 - ajaxm:ajaxm/rustup-update, r=komaeda
Suggest rustup update in readme I'm pretty new to Rust. I tried installing rustlings for the first time and got this error: ``` $> cargo install --force --path . error: `/Users/ajax/projects/rust/rustlings` is not a crate root; specify a crate to install from crates.io, or use --path or --git to specify an alternate source Caused by: failed to parse manifest at `/Users/ajax/projects/rust/rustlings/Cargo.toml` Caused by: editions are unstable Caused by: feature `edition` is required this Cargo does not support nightly features, but if you switch to nightly channel you can add `cargo-features = ["edition"]` to enable this feature ``` I'm not sure if the answer was to run `rustup update` but I noticed that I was running Rust 1.29.0, so updated to 1.36.0 and got it working. If there's a way to specify a minimum required version, pls let me know. Lastly, the whitespace changes were automatic from my editor. What's the convention here for making such updates? Thanks!
