README.md: `gem "sinatra-param"` instead of `gem "sinatra-param", require: "sinatra/param"`

[pjmartorell]

It's not needed to put the require option in the Gemfile, since your gem already requires everything you have in lib folder.

So in your Gemfile you can simply put: gem "sinatra-param"
Instead of: gem "sinatra-param", require: "sinatra/param"
