 **Important:** You are encouraged to use a dedicated secret key, different than others in use in your application. If several components share the same secret key, chances that a vulnerability in one of them has a wider impact increase. Also, never share your secrets pushing it to a remote repository, you are better off using an environment variable like in the example.
 
 Currently, HS256 algorithm is the default.
-Configure the matching secret and algorithm name to use a different one (e.g. RS256)
+Configure the matching secret and algorithm name to use a different one (e.g. RS256) (see [ruby-jwt](https://github.com/jwt/ruby-jwt#algorithms-and-usage) to see which are supported)
 ```ruby
 Warden::JWTAuth.configure do |config|
   config.secret = OpenSSL::PKey::RSA.new(ENV['WARDEN_JWT_SECRET_KEY'])
