-Make R speakable\!
+Make R speakable!
 
 The goal of {r2eng} (as in ‘R to English’) is to take an R expression
 and ‘translate’ it to an English sentence.
 
 The package is intended to:
 
-  - improve communication between teachers and learners
-  - make R discussions in English more accessible to non-English
-    speakers
-  - provide an extra audio evaluation tool for users who are blind or
-    have low vision
-  - be of interest to any R user that’s curious about how R expressions
-    might be vocalised
