 # Ripper translation
 
-Prism provides the ability to mirror the `Ripper` standard library. You can do this by:
-
-```ruby
-require "prism/translation/ripper/shim"

-This provides the APIs like:

-```ruby
-Ripper.lex
-Ripper.parse
-Ripper.sexp_raw
-Ripper.sexp

-Ripper::SexpBuilder
-Ripper::SexpBuilderPP
