 However, before submitting, please review the following:

- - Please manually confirm that your changes, and all tests, pass in `bash`, `sh`, and `zsh`. We hope to soon automatically run all these tests, but in the meantime, we have to rely on each contributor doing so.
+ - Please manually confirm that your changes work in `bash`, `sh`/`dash`, `ksh`, and `zsh`. Fast tests do run in these shells, but it's nice to manually verify also.

  - Any time you make a change to your PR, please rebase freshly on top of master. Nobody likes merge commits.
