 However, before submitting, please review the following:
 
  - Please include tests. Changes with tests will be merged very quickly.
- - 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.
  - Please maintain consistent whitespace - 2-space indentation, trailing newlines in all files, etc.
  - Any time you make a change to your PR, please rebase freshly on top of master. Nobody likes merge commits.
