 Here's a quick checklist that should be present in PRs:
 
-- [ ] Target: for bug or doc fixes, target `master`; for new features, target `features`;
+- [ ] Add a new news fragment into the changelog folder
+  * name it `$issue_id.$type` for example (588.bug)
+  * if you don't have an issue_id change it to the pr id after creating the pr
+  * ensure type is one of `removal`, `feature`, `bugfix`, `vendor`, `doc` or `trivial`
+  * Make sure to use full sentences with correct case and punctuation, for example: "Fix issue with non-ascii contents in doctest text files."
+- [ ] Target: for `bugfix`, `vendor`, `doc` or `trivial` fixes, target `master`; for removals or features target `features`;
+- [ ] Make sure to include reasonable tests for your change if necessary
 
-Unless your change is trivial documentation fix (e.g.,  a typo or reword of a small section) please:
+Unless your change is a trivial or a documentation fix (e.g.,  a typo or reword of a small section) please:
 
-- [ ] Make sure to include one or more tests for your change;
 - [ ] Add yourself to `AUTHORS`;
-- [ ] Add a new entry to `CHANGELOG.rst`
-  * Choose any open position to avoid merge conflicts with other PRs.
-  * Add a link to the issue you are fixing (if any) using RST syntax.
-  * The pytest team likes to have people to acknowledged in the `CHANGELOG`, so please add a thank note to yourself ("Thanks @user for the PR") and a link to your GitHub profile. It may sound weird thanking yourself, but otherwise a maintainer would have to do it manually before or after merging instead of just using GitHub's merge button. This makes it easier on the maintainers to merge PRs.
