Welcome to Code Review Stack Exchange
Code Review is a question and answer site for sharing code from projects you are working on for peer review.
It's built and run by you as part of the Stack Exchange network of Q&A sites.
With your help, we're working together to build a library of detailed code reviews.
That wording has been in place since January 2013, and it just echoes the standard formulaic greeting used on most other Stack Exchange sites.
I don't think that the wording suits us. How should be better summarize our mission to newcomers?
