In conversations in Slack @MaineC has shared many great tips about how to keep the number of contributors to a project healthy. Her tips are focused on

1. increasing the number of contributors
2. helping contributors to level up into the role of Trusted Committer

We would like to interview her about these topics, and see how we could turn this content into a pattern.

See our full pattern syntax to understand the type of information we would like to extract by doing an interview.

首先阅读 meta/pattern-template.md，了解所需的模式结构，然后与 MaineC 安排一次访谈，讨论如何招募贡献者并帮助他们成为 Trusted Committers。完成的标准是将访谈内容整理成遵循仓库完整模式语法的模式草稿。
