-**Note on [Typhoeus](https://github.com/typhoeus/typhoeus)**: Typhoeus is compatible and will be automatically detected too. However, the latest release (v1.3.1 at the moment of writing this) is not compatible with Faraday 1.0. [It still uses the deprecated `Faraday::Error` namespace](https://github.com/typhoeus/typhoeus/blob/v1.3.1/lib/typhoeus/adapters/faraday.rb#L100). If you want to use it with this gem, we suggest getting `master` from GitHub, since this has been fixed for v1.4.0. We'll update this if/when v1.4.0 is released.a
+**Note on [Typhoeus](https://github.com/typhoeus/typhoeus)**: You need to use v1.4.0 or up since older versions are not compatible with Faraday 1.0.
