All PRs must tick these:

• [ ] I have read the CONTRIBUTING document.
• [ ] All commits signed-off for the Developer Certification of Origin.

With occasional exceptions, all PRs from Progress employees must tick these:

• [ ] Is the code clear? (complicated code or lots of comments--subdivide and use well-named methods, meaningful variable names, etc.)
• [ ] Consistency checked? (user notifications, user prompts, visual patterns, code patterns, variable names)
• [ ] Repeated code blocks eliminated? (adapt and reuse existing components, blocks, functions, etc.)
• [ ] Spelling, grammar, typos checked? (at a minimum use make spell in any component directory)
• [ ] Code well-formatted? (indents, line breaks, etc. improve rather than hinder readability)

All PRs from Progress employees should tick these if appropriate:

• [ ] Tests added/updated? (all new code needs new tests)
• [ ] Docs added/updated? (all customer-facing changes)

Please add a note next to any checkbox above if you are NOT ticking it.
