Overview

We need to remove references to "good second issue" from CONTRIBUTING.md in order to avoid confusion, since we are no longer creating issues with the label `Complexity: good second issue'.

Action Items

• In your local IDE, navigate to CONTRIBUTING.md and locate Section 2.2
• Remove

* `complexity: good second issue`

• Changes to CONTRIBUTING.md cannot be tested locally, rather they must be tested after pushing the issue branch to your fork of the repository. Push your issue branch in the usual manner, but before creating the Pull Request, check your updates using this test URL. Also store the test URL for use in a later step:

https://github.com/[REPLACE WITH GITHUB HANDLE]/website/blob/[REPLACE WITH NAME OF ISSUE BRANCH]/C- ONTRIBUTING.md

(for example: https://github.com/bonniewolfe/website/blob/issue-branch-1234/CONTRIBUTING.md)

• Create a pull request with your changes. In the Pull Request, after the "Why did you make the changes" section, add this line to help reviewers, replacing the text in brackets (and the brackets) with the test URL from the previous Action Item.

For Reviewers: Do not review locally, rather review changes at [REPLACE WITH TEST URL]

For Merge Team

• Resolve the dependency on this issue in Creating issues to remove all "good second issue" references in CONTRIBUTING.md #4506. If all dependencies have been resolved, close that issue.
