 === Configuring Erlang/OTP versions to test
 
 To use the CI plugin you must first configure which versions
-of Erlang/OTP will be used. Erlang.mk provides three separate
-configuration variables depending on whether you need a normal
-OTP release, a HiPE-enabled release or an ErLLVM-enabled release.

 At the time of writing, this is how you would test against all
