+# Pull Request
+
+<!--
+The text in these markdown comments is instructions that will not appear in the displayed pull request,
+and can be deleted.
+
+Please submit pull requests against the develop branch.
+
+Follow the existing code style. Check the tests succeed, including lint.
+  npm run test
+  npm run lint
+
+Don't update the CHANGELOG or command version number. That gets done by maintainers when preparing the release.
+
+Commander currently has zero production dependencies. That isn't a hard requirement, but is a simple story. Requests which 
+add a dependency are much less likely to be accepted, and we are likely to ask if there alternative approaches to avoid the dependency.

+## Solution
+
+<!--
+How did you solve the problem? 
+Show the fixed output if appropriate.
+
+There are a lot of forms of documentation which could need updating for a change in functionality. It
+is ok if you want to show us the code to discuss before doing the extra work, and
+you should say so in your comments so we focus on the concept first before talking about all the other pieces:
+
+- TypeScript typings
+- JSDoc documentation in code
+- tests
+- README
+- examples/
+-->
+
+## ChangeLog
+
+<!--
+Optional. Suggest a line for adding to the CHANGELOG to summarise your change.
