What is the best practice for making suggestions to improve documentation

I’ve read quite a few posts relating to problems with documentation in ember, and encountered a situation where I would want to suggest a change to the documentation Should all server communication happen in the router - #4 by varblob But I’m not sure how to approach this.

  1. I looked at the ember.js website repo and found there were other instances of people suggesting documentation changes, there were also some in the ember.js repo. Which repo should documentation suggestions / requests goto?
  2. I know everyone is busy so the best way to make a suggestion would be to include a pull request but I’m also not really sure if my suggestion is fully inline with current / future ember design. Where is the appropriate place to vet / expand a suggestion?
